building JCC on Python 2.4

[Felix Schwarz <fe...@web.de>]

Hey,

I'm trying to build JCC on Python 2.4.3 (CentOS 5). However during the
compilation I get this error:
gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fPIC

jcc/sources/JArray.cpp:1213: error: expected `}' at end of input
jcc/sources/JArray.h: In constructor 'JArray<T>::JArray(_jobject*)':

Well, I could work around that one with a patch (see attached) but afterwards
compilation still fails:
gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector

_jcc/java/lang/Class.h:49: error: ISO C++ forbids declaration of 'JArray' with
no type
_jcc/java/lang/Class.h:49: error: expected ';' before '<' token

I'm using GCC 4.1.2:
gcc-4.1.2-52.el5_8.1
gcc-c++-4.1.2-52.el5_8.1

Any idea what I'm doing wrong? Do you need more info?

That worked, thank you.

Thank you for your patch !

I integrated it after indenting a few more things and published the site.
http://lucene.apache.org/pylucene/jcc/features.html

It would be nice to figure out how to get the JCC subsite to inherit the 
style sheet used by the rest of the entire site.

If you don't tell me what error, it's that much harder to help you.

I took a quick look and your changes did not have much effect.
Please test your changes using the CMS build system.
For example, it seems that your addition of ``` line 23 in features.mdtext 
had no effect.

It's going to be very difficult to do this blind.

Did you follow all the steps listed in in LUCENE-2748 comment I sent you a 
link to, in particular, what's described at 
http://www.apache.org/dev/cmsref.html#local-build, especially these steps 
listed there ?
$ cd /path/to/cms/build/tree
$ export MARKDOWN_SOCKET=`pwd`/markdown.socket PYTHONPATH=`pwd`
$ python markdownd.py

Thanks for trying but if I end up spending more time debugging what you send 
me than doing it myself, the situation is even worse and going nowhere :-(

Cheers !

Hi,

Attached is an diff update to the mdtext files with jcc documentation.

I didn't manage to get the site build system to work, I think a perl markdown module is needed, which I get build error when installing.

However there are some mdtext editors around, so I just updated some of the text in there, please check that it looks ok before activating.

Best Regards

The new site's source is checked into svn:
   http://svn.apache.org/repos/asf/lucene/cms/trunk

Check this out into a directory of yours.
The pylucene directory is under content/pylucene.

To build a copy of the site to review and debug your edits, please refer to 
this comment in the Lucene issue tracking the transition, LUCENE-2748:
https://issues.apache.org/jira/browse/LUCENE-2748?focusedCommentId=13080471&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13080471

Once you're satisfied with your changes, send a patch to the pylucene-dev 
mailing list and I'll apply them.

Thanks !

Andi..

Please, don't hijack a thread, start a new one when switching topics. Your questions below have nothing to do with building on Python 2.4.

Use dir() on the wrapper class to see what got wrapped. But to get a definite answer you need to look at the generated source code to know about all the overloads of a Java method that got wrapped.

No, only if it is used by any of the classes or jars you explicitely asked be wrapped.

Yes, the software behind the site was switched and a bunch of work is needed to fix the content up. Volunteers are welcome to help out with this. If you'd like to contribute I can send you instructions.

Dear Andi,

I am trying to clean up my wrap script and comes to some questions. 

Is there a way to see if a method or constructor is now wrapped due to that any of its inputs/outputs are not wrapped? (to make sure that I haven't missed any --package)

If i "--package java.io" does that mean that all classes in that package such as "java.io.InputStream" is automatically packaged?

BTW, it seems like the formatting of the docs has become a bit corrupted at: http://lucene.apache.org/pylucene/jcc/readme.html 

Many thanks
/Petrus

In your patch, instead of including "functions.h", add this to JArray.h 
after the #include "macros.h" line:

#if PY_VERSION_HEX < 0x02050000
typedef int Py_ssize_t;
#endif

I don't have a Python 2.4 install readily available to test this so I hope 
this just works.
