[Problem] Not able to Link APR to my programs
I am new to APR. I am going to use it for developing a Apache like hybrid
architecture for OpenSIPS [www.opensips.org], which an open source SIP[RFC
3261] server.
I have downloaded APR and installed it on my Fedora 9 machine using the
configure and make commands. I tested the installation with testall. But I
am not able to use this in my programs and not able to link to the header
files in APR.
I am using a cat1.c program to run, in which I am using functions of APR
module. I have tried these gcc commands:
gcc -l lapr-1 /cat1.c
*gcc /cat1.c -L. -lapr-1*
my working directory is
*/usr/local/apr/lib*
I am getting following set of errors:
/cat1.c:1:23: error: apr_pools.h: No such file or directory
/cat1.c:2:25: error: apr_file_io.h: No such file or directory
/cat1.c: In function ‘main’:
/cat1.c:8: error: ‘apr_pool_t’ undeclared (first use in this function)
/cat1.c:8: error: (Each undeclared identifier is reported only once
/cat1.c:8: error: for each function it appears in.)
/cat1.c:8: error: ‘pool’ undeclared (first use in this function)

/cat1.c:29: error: ‘bytes’ undeclared (first use in this function)
/cat1.c:29: warning: incompatible implicit declaration of built-in function
‘strlen’
Can some one help me where I am lacking. Can some one track my mistake. I
will be very grateful if someone can do that. :)
Thank You in advance.

find where it installs apr-1-config and look at the help text for
apr-1-config to see which flags you need for compiling and linking (that
will handle finding apr header files)
Re: [Problem] Not able to Link APR to my programs
Posted by SAMEER KUMAR <sa...@gmail.com>.
Thanks to everyone for suggesting the solutions,
I tried, as proposed by various users and developers in response to my
query, using the -I<path of apr-$installedversion-config>. That too did not
work. Finally I managed to serve my purpose using gcc command, executing
apr-$installedversion-config file (ie apr-1-config installed in
/usr/local/apr/bin in my case). I use this file to print the options
required for complition using APR library.
Here is a snapshot of what I used:
[root@a104cc-user86 bin]# gcc $(./apr-1-config --includes) $(./apr-1-config
--libs) $(./apr-1-config --link-ld) $(./apr-1-config --cflags)
$(./apr-1-config --cppflags) /cat.c
The options I have used with ./apr-1-config can be better undestood by
simply executing that file at shell.
Thanks once again for helping us.

You're not finding the installed APR headers. Try adding apr-1-config
--includes to your compiler flags.
(you might need to find where apr-1-config was installed when you built apr)

Maybe that works for you? I could not find the previous post
$> export APR_LIBS="`apr-1-config --cflags --cppflags --includes --
ldflags --link-ld --libs`"
$> export APU_LIBS="`apu-1-config --includes --ldflags --link-ld --

We are trying to modify an existing SIP server, OpenSIPS. SIP is session
Initiation Protocol [RFC3261]. SIP has request methods and response codes
very much like http. It is a protocol for multimedia session handling. I
will consider your advice for writing an Apache plugin.

Do you have a e-book of this? Or any idea from where can I get it? It would
be kind of you if you can help.

I had found that apr_*something*.mk file in my /usr/local/apr/build-1. I had
already tried adding that as -I but still that seemed to be of no use. I
could not locate apr-1-config file. Can you give me a hint where it might be
located with respect to the installatin directory of APR.
Thanks once again for replying.

Sameer:
You are missing the include path, specified with -I; you can get the correct
syntax for your build by using apr-1-config.
That said, if you are planning on building something that resembles a web
server, may I suggest writing an Apache module (plug-in) rather than using
APR to build a web server? You'll get where you want to go a lot faster.
