- Zookeeper C queue client library
-
-
-INSTALLATION
-
-If you're building the client from a source checkout you need to
-follow the steps outlined below. If you're building from a release
-tar downloaded from Apache please skip to step 2.
-
-This recipe does not handle ZCONNECTIONLOSS. It will only work correctly once ZOOKEEPER-22 https://issues.apache.org/jira/browse/ZOOKEEPER-22 is resolved.
-
-1) make sure that you compile the main zookeeper c client library.
-
-2) change directory to src/recipes/queue/src/c
- and do a "autoreconf -if" to bootstrap
- autoconf, automake and libtool. Please make sure you have autoconf
- version 2.59 or greater installed.
-3) do a "./configure [OPTIONS]" to generate the makefile. See INSTALL
- for general information about running configure.
-
-4) do a "make" or "make install" to build the libraries and install them.
- Alternatively, you can also build and run a unit test suite (and
- you probably should). Please make sure you have cppunit-1.10.x or
- higher installed before you execute step 4. Once ./configure has
- finished, do a "make run-check". It will build the libraries, build
- the tests and run them.
-5) to generate doxygen documentation do a "make doxygen-doc". All
- documentations will be placed to a new subfolder named docs. By
- default only HTML documentation is generated. For information on
- other document formats please use "./configure --help"

-
-# Generate automatic documentation using Doxygen. Works in concert with the
-# aminclude.m4 file and a compatible doxygen configuration file. Defines the
-# following public macros:
-#
-# DX_???_FEATURE(ON|OFF) - control the default setting of a Doxygen feature.
-# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
-# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
-# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
-# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
-# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
-# paper size.
-#
-# By default, HTML, PDF and PS documentation is generated as this seems to be
-# the most popular and portable combination. MAN pages created by Doxygen are
-# usually problematic, though by picking an appropriate subset and doing some
-# massaging they might be better than nothing. CHM and RTF are specific for MS
-# (note that you can't generate both HTML and CHM at the same time). The XML is
-# rather useless unless you apply specialized post-processing to it.
-#
-# The macro mainly controls the default state of the feature. The use can
-# override the default by specifying --enable or --disable. The macros ensure
-# that contradictory flags are not given (e.g., --enable-doxygen-html and
-# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
-# Finally, each feature will be automatically disabled (with a warning) if the
-# required programs are missing.
-#
-# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
-# the following parameters: a one-word name for the project for use as a
-# filename base etc., an optional configuration file name (the default is
-# 'Doxyfile', the same as Doxygen's default), and an optional output directory
-# name (the default is 'doxygen-doc').

+/**
+ * <p>
+ * A leader election support library implementing the ZooKeeper election recipe.
+ * </p>
+ * <p>
+ * This support library is meant to simplify the construction of an exclusive
+ * leader system on top of Apache ZooKeeper. Any application that can become the
+ * leader (usually a process that provides a service, exclusively) would
+ * configure an instance of this class with their hostname, at least one
+ * listener (an implementation of {@link LeaderElectionAware}), and either an
+ * instance of {@link ZooKeeper} or the proper connection information. Once
+ * configured, invoking {@link #start()} will cause the client to connect to
+ * ZooKeeper and create a leader offer. The library then determines if it has
+ * been elected the leader using the algorithm described below. The client
+ * application can follow all state transitions via the listener callback.
+ * </p>
+ * <p>
+ * Leader election algorithm
+ * </p>
+ * <p>
+ * The library starts in a START state. Through each state transition, a state
+ * start and a state complete event are sent to all listeners. When
+ * {@link #start()} is called, a leader offer is created in ZooKeeper. A leader
+ * offer is an ephemeral sequential node that indicates a process that can act
+ * as a leader for this service. A read of all leader offers is then performed.
+ * The offer with the lowest sequence number is said to be the leader. The
+ * process elected leader will transition to the leader state. All other
+ * processes will transition to a ready state. Internally, the library creates a
+ * ZooKeeper watch on the leader offer with the sequence ID of N - 1 (where N is
+ * the process's sequence ID). If that offer disappears due to a process
+ * failure, the watching process will run through the election determination
+ * process again to see if it should become the leader. Note that sequence ID
+ * may not be contiguous due to failed processes. A process may revoke its offer
+ * to be the leader at any time by calling {@link #stop()}.
+ * </p>
+ * <p>
+ * Guarantees (not) Made and Caveats
+ * </p>
+ * <p>
+ * <ul>
+ * <li>It is possible for a (poorly implemented) process to create a leader
+ * offer, get the lowest sequence ID, but have something terrible occur where it
+ * maintains its connection to ZK (and thus its ephemeral leader offer node) but
+ * doesn't actually provide the service in question. It is up to the user to
+ * ensure any failure to become the leader - and whatever that means in the
+ * context of the user's application - results in a revocation of its leader
+ * offer (i.e. that {@link #stop()} is called).</li>
+ * <li>It is possible for ZK timeouts and retries to play a role in service
+ * liveliness. In other words, if process A has the lowest sequence ID but
+ * requires a few attempts to read the other leader offers' sequence IDs,
+ * election can seem slow. Users should apply timeouts during the determination
+ * process if they need to hit a specific SLA.</li>
+ * <li>The library makes a "best effort" to detect catastrophic failures of the
+ * process. It is possible that an unforeseen event results in (for instance) an
+ * unchecked exception that propagates passed normal error handling code. This
+ * normally doesn't matter as the same exception would almost certain destroy
+ * the entire process and thus the connection to ZK and the leader offer
+ * resulting in another round of leader determination.</li>
+ * </ul>
+ * </p>

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+ Zookeeper C lock client library
+
+
+INSTALLATION
+
+If you're building the client from a source checkout you need to
+follow the steps outlined below. If you're building from a release
+tar downloaded from Apache please skip to step 2.
+
+1) make sure that you compile the main zookeeper c client library.
+
+2) change directory to src/recipes/lock/src/c
+ and do a "autoreconf -if" to bootstrap
+ autoconf, automake and libtool. Please make sure you have autoconf
+ version 2.59 or greater installed.
+3) do a "./configure [OPTIONS]" to generate the makefile. See INSTALL
+ for general information about running configure.
+
+4) do a "make" or "make install" to build the libraries and install them.
+ Alternatively, you can also build and run a unit test suite (and
+ you probably should). Please make sure you have cppunit-1.10.x or
+ higher installed before you execute step 4. Once ./configure has
+ finished, do a "make run-check". It will build the libraries, build
+ the tests and run them.
+5) to generate doxygen documentation do a "make doxygen-doc". All
+ documentations will be placed to a new subfolder named docs. By
+ default only HTML documentation is generated. For information on
+ other document formats please use "./configure --help"

+# This file is part of Autoconf. -*- Autoconf -*-

+# This file is distributed under the same terms as the Autoconf macro files.
+
+# Generate automatic documentation using Doxygen. Works in concert with the
+# aminclude.m4 file and a compatible doxygen configuration file. Defines the
+# following public macros:
+#
+# DX_???_FEATURE(ON|OFF) - control the default setting of a Doxygen feature.
+# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
+# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
+# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
+# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
+# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
+# paper size.
+#
+# By default, HTML, PDF and PS documentation is generated as this seems to be
+# the most popular and portable combination. MAN pages created by Doxygen are
+# usually problematic, though by picking an appropriate subset and doing some
+# massaging they might be better than nothing. CHM and RTF are specific for MS
+# (note that you can't generate both HTML and CHM at the same time). The XML is
+# rather useless unless you apply specialized post-processing to it.
+#
+# The macro mainly controls the default state of the feature. The use can
+# override the default by specifying --enable or --disable. The macros ensure
+# that contradictory flags are not given (e.g., --enable-doxygen-html and
+# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
+# Finally, each feature will be automatically disabled (with a warning) if the
+# required programs are missing.
+#
+# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
+# the following parameters: a one-word name for the project for use as a
+# filename base etc., an optional configuration file name (the default is
+# 'Doxyfile', the same as Doxygen's default), and an optional output directory
+# name (the default is 'doxygen-doc').

+ * The take_latch structure roughly emulates a Java CountdownLatch with 1 as the initial value.

+ *
+ * This latch is specialized to be used with the queue, all latches created for the same queue structure will use the same mutex.
+ *
+ * The setter thread at some point will call take_latch_setter_trigger_latch() on the thread.

+ * The waiter thread creates the latch and at some point either calls take_latch_waiter_await()s or take_latch_waiter_mark_unneeded()s it.
+ * The await function will return after the setter thread has triggered the latch.
+ * The mark unneeded function will return immediately and avoid some unneeded initialization.
+ *
+ * Whichever thread is last to call their required function disposes of the latch.
+ *
+ * The latch may disposed if no threads will call the waiting, marking, or triggering functions using take_latch_destroy_syncrhonized().

+1) This queue interface recipe implements the queue recipe
+mentioned in ../../../docs/recipes.[html,pdf].
+A more detailed explanation is at http://www.cloudera.com/blog/2009/05/28/building-a-distributed-concurrent-queue-with-apache-zookeeper/
+
+2) This recipe does not handle KeeperException.ConnectionLossException or ZCONNECTIONLOSS. It will only work correctly once ZOOKEEPER-22 https://issues.apache.org/jira/browse/ZOOKEEPER-22 is resolved.
+
+3) To compile the queue java recipe you can just run ant jar from
+this directory.
+Please report any bugs on the jira

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+ Zookeeper C queue client library
+
+
+INSTALLATION
+
+If you're building the client from a source checkout you need to
+follow the steps outlined below. If you're building from a release
+tar downloaded from Apache please skip to step 2.
+
+This recipe does not handle ZCONNECTIONLOSS. It will only work correctly once ZOOKEEPER-22 https://issues.apache.org/jira/browse/ZOOKEEPER-22 is resolved.
+
+1) make sure that you compile the main zookeeper c client library.
+
+2) change directory to src/recipes/queue/src/c
+ and do a "autoreconf -if" to bootstrap
+ autoconf, automake and libtool. Please make sure you have autoconf
+ version 2.59 or greater installed.
+3) do a "./configure [OPTIONS]" to generate the makefile. See INSTALL
+ for general information about running configure.
+
+4) do a "make" or "make install" to build the libraries and install them.
+ Alternatively, you can also build and run a unit test suite (and
+ you probably should). Please make sure you have cppunit-1.10.x or
+ higher installed before you execute step 4. Once ./configure has
+ finished, do a "make run-check". It will build the libraries, build
+ the tests and run them.
+5) to generate doxygen documentation do a "make doxygen-doc". All
+ documentations will be placed to a new subfolder named docs. By
+ default only HTML documentation is generated. For information on
+ other document formats please use "./configure --help"

+# This file is part of Autoconf. -*- Autoconf -*-

+# This file is distributed under the same terms as the Autoconf macro files.
+
+# Generate automatic documentation using Doxygen. Works in concert with the
+# aminclude.m4 file and a compatible doxygen configuration file. Defines the
+# following public macros:
+#
+# DX_???_FEATURE(ON|OFF) - control the default setting of a Doxygen feature.
+# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
+# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
+# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
+# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
+# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
+# paper size.
+#
+# By default, HTML, PDF and PS documentation is generated as this seems to be
+# the most popular and portable combination. MAN pages created by Doxygen are
+# usually problematic, though by picking an appropriate subset and doing some
+# massaging they might be better than nothing. CHM and RTF are specific for MS
+# (note that you can't generate both HTML and CHM at the same time). The XML is
+# rather useless unless you apply specialized post-processing to it.
+#
+# The macro mainly controls the default state of the feature. The use can
+# override the default by specifying --enable or --disable. The macros ensure
+# that contradictory flags are not given (e.g., --enable-doxygen-html and
+# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
+# Finally, each feature will be automatically disabled (with a warning) if the
+# required programs are missing.
+#
+# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
+# the following parameters: a one-word name for the project for use as a
+# filename base etc., an optional configuration file name (the default is
+# 'Doxyfile', the same as Doxygen's default), and an optional output directory
+# name (the default is 'doxygen-doc').

- Zookeeper C lock client library
-
-
-INSTALLATION
-
-If you're building the client from a source checkout you need to
-follow the steps outlined below. If you're building from a release
-tar downloaded from Apache please skip to step 2.
-
-1) make sure that you compile the main zookeeper c client library.
-
-2) change directory to src/recipes/lock/src/c
- and do a "autoreconf -if" to bootstrap
- autoconf, automake and libtool. Please make sure you have autoconf
- version 2.59 or greater installed.
-3) do a "./configure [OPTIONS]" to generate the makefile. See INSTALL
- for general information about running configure.
-
-4) do a "make" or "make install" to build the libraries and install them.
- Alternatively, you can also build and run a unit test suite (and
- you probably should). Please make sure you have cppunit-1.10.x or
- higher installed before you execute step 4. Once ./configure has
- finished, do a "make run-check". It will build the libraries, build
- the tests and run them.
-5) to generate doxygen documentation do a "make doxygen-doc". All
- documentations will be placed to a new subfolder named docs. By
- default only HTML documentation is generated. For information on
- other document formats please use "./configure --help"

-# This file is part of Autoconf. -*- Autoconf -*-

-# This file is distributed under the same terms as the Autoconf macro files.
-
-# Generate automatic documentation using Doxygen. Works in concert with the
-# aminclude.m4 file and a compatible doxygen configuration file. Defines the
-# following public macros:
-#
-# DX_???_FEATURE(ON|OFF) - control the default setting of a Doxygen feature.
-# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
-# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
-# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
-# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
-# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
-# paper size.
-#
-# By default, HTML, PDF and PS documentation is generated as this seems to be
-# the most popular and portable combination. MAN pages created by Doxygen are
-# usually problematic, though by picking an appropriate subset and doing some
-# massaging they might be better than nothing. CHM and RTF are specific for MS
-# (note that you can't generate both HTML and CHM at the same time). The XML is
-# rather useless unless you apply specialized post-processing to it.
-#
-# The macro mainly controls the default state of the feature. The use can
-# override the default by specifying --enable or --disable. The macros ensure
-# that contradictory flags are not given (e.g., --enable-doxygen-html and
-# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
-# Finally, each feature will be automatically disabled (with a warning) if the
-# required programs are missing.
-#
-# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
-# the following parameters: a one-word name for the project for use as a
-# filename base etc., an optional configuration file name (the default is
-# 'Doxyfile', the same as Doxygen's default), and an optional output directory
-# name (the default is 'doxygen-doc').

-# are controlled by the various DX_COND_??? conditionals set by autoconf.
-#
-# The provided goals are:
-# doxygen-doc: Generate all doxygen documentation.
-# doxygen-run: Run doxygen, which will generate some of the documentation
-# (HTML, CHM, CHI, MAN, RTF, XML) but will not do the post
-# processing required for the rest of it (PS, PDF, and some MAN).
-# doxygen-man: Rename some doxygen generated man pages.
-# doxygen-ps: Generate doxygen PostScript documentation.
-# doxygen-pdf: Generate doxygen PDF documentation.
-#
-# Note that by default these are not integrated into the automake goals. If
-# doxygen is used to generate man pages, you can achieve this integration by
-# setting man3_MANS to the list of man pages generated and then adding the
-# dependency:
-#
-# $(man3_MANS): doxygen-doc
-#
-# This will cause make to run doxygen and generate all the documentation.

-1) This queue interface recipe implements the queue recipe
-mentioned in ../../../docs/recipes.[html,pdf].
-A more detailed explanation is at http://www.cloudera.com/blog/2009/05/28/building-a-distributed-concurrent-queue-with-apache-zookeeper/
-
-2) This recipe does not handle KeeperException.ConnectionLossException or ZCONNECTIONLOSS. It will only work correctly once ZOOKEEPER-22 https://issues.apache.org/jira/browse/ZOOKEEPER-22 is resolved.
-
-3) To compile the queue java recipe you can just run ant jar from
-this directory.
-Please report any bugs on the jira

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
-2006 Free Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package. The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about. Run `./configure --help' for
-details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug. Until the bug is fixed you can use this workaround:
-
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

+1) This source directory contains various Zookeeper recipe implementations.
+
+2) The recipe directory name should specify the name of the recipe you are implementing - eg. zookeeper-recipes-lock/.
+
+3) It would be great if you can provide both the java and c recipes for the zookeeper recipes.
+ C recipes go in to zookeeper-recipes/zookeeper-recipes-[recipe-name]/src/c
+ Java implementation goes into zookeeper-recipes/zookeeper-recipes-[recipe-name]/src/java.
+
+4) The recipes hold high standards like our zookeeper c/java libraries, so make sure that you include
+some unit testing with both the c and java recipe code.
+
+5) Also, please name your c client public methods as
+zkr_recipe-name_methodname
+(eg. zkr_lock_lock in zookeeper-recipes-lock/src/c)
+
+6) The various recipes are in ../docs/recipes.html or
+../../docs/reciped.pdf. Also, this is not an exhaustive list by any chance.
+Zookeeper is used (and can be used) for more than what we have listed in the docs.
+
+7) To run the c tests in all the recipes,
+- make sure the main zookeeper c libraries in
+{top}/src/c/ are compiled. Run autoreconf -if;./configure; make. The libaries
+will be installed in {top}/src/c/.libs.
+- run autoreconf if;./configure;make run-check
+ in zookeeper-recipes/$recipename/src/c

-1) This source directory contains various Zookeeper recipe implementations.
-
-2) The recipe directory name should specify the name of the recipe you are implementing - eg. lock/.
-
-3) It would be great if you can provide both the java and c recipes for the zookeeper recipes.
-The c recipes go in to recipe-name/src/c and the java implementation goes into recipe-name/src/java.
-
-4) The recipes hold high standards like our zookeeper c/java libraries, so make sure that you include
-some unit testing with both the c and java recipe code.
-
-5) Also, please name your c client public methods as
-zkr_recipe-name_methodname
-(eg. zkr_lock_lock in lock/src/c)
-
-6) The various recipes are in ../../docs/recipes.html or
-../../docs/reciped.pdf. Also, this is not an exhaustive list by any chance.
-Zookeeper is used (and can be used) for more than what we have listed in the docs.
-
-7) To run the c tests in all the recipes,
-- make sure the main zookeeper c libraries in
-{top}/src/c/ are compiled. Run autoreconf -if;./configure; make. The libaries
-will be installed in {top}/src/c/.libs.
-- run autoreconf if;./configure;make run-check
- in src/recipes/$recipename/src/c

-/**
- * <p>
- * A leader election support library implementing the ZooKeeper election recipe.
- * </p>
- * <p>
- * This support library is meant to simplify the construction of an exclusive
- * leader system on top of Apache ZooKeeper. Any application that can become the
- * leader (usually a process that provides a service, exclusively) would
- * configure an instance of this class with their hostname, at least one
- * listener (an implementation of {@link LeaderElectionAware}), and either an
- * instance of {@link ZooKeeper} or the proper connection information. Once
- * configured, invoking {@link #start()} will cause the client to connect to
- * ZooKeeper and create a leader offer. The library then determines if it has
- * been elected the leader using the algorithm described below. The client
- * application can follow all state transitions via the listener callback.
- * </p>
- * <p>
- * Leader election algorithm
- * </p>
- * <p>
- * The library starts in a START state. Through each state transition, a state
- * start and a state complete event are sent to all listeners. When
- * {@link #start()} is called, a leader offer is created in ZooKeeper. A leader
- * offer is an ephemeral sequential node that indicates a process that can act
- * as a leader for this service. A read of all leader offers is then performed.
- * The offer with the lowest sequence number is said to be the leader. The
- * process elected leader will transition to the leader state. All other
- * processes will transition to a ready state. Internally, the library creates a
- * ZooKeeper watch on the leader offer with the sequence ID of N - 1 (where N is
- * the process's sequence ID). If that offer disappears due to a process
- * failure, the watching process will run through the election determination
- * process again to see if it should become the leader. Note that sequence ID
- * may not be contiguous due to failed processes. A process may revoke its offer
- * to be the leader at any time by calling {@link #stop()}.

- * Guarantees (not) Made and Caveats
- * </p>
- * <p>
- * <ul>
- * <li>It is possible for a (poorly implemented) process to create a leader
- * offer, get the lowest sequence ID, but have something terrible occur where it
- * maintains its connection to ZK (and thus its ephemeral leader offer node) but
- * doesn't actually provide the service in question. It is up to the user to
- * ensure any failure to become the leader - and whatever that means in the
- * context of the user's application - results in a revocation of its leader
- * offer (i.e. that {@link #stop()} is called).</li>
- * <li>It is possible for ZK timeouts and retries to play a role in service
- * liveliness. In other words, if process A has the lowest sequence ID but
- * requires a few attempts to read the other leader offers' sequence IDs,
- * election can seem slow. Users should apply timeouts during the determination
- * process if they need to hit a specific SLA.</li>
- * <li>The library makes a "best effort" to detect catastrophic failures of the
- * process. It is possible that an unforeseen event results in (for instance) an
- * unchecked exception that propagates passed normal error handling code. This
- * normally doesn't matter as the same exception would almost certain destroy
- * the entire process and thus the connection to ZK and the leader offer
- * resulting in another round of leader determination.</li>
- * </ul>

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
-2006 Free Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package. The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about. Run `./configure --help' for
-details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug. Until the bug is fixed you can use this workaround:
-
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.
