Hi,
I'm trying to wrap the LingPipe library (http://alias-i.com/lingpipe/web/download.html
) using JCC.
I've had a couple of problems - one seems to be fixed by simply
excluding a class that I don't think I need (I can also post
separate info about that problem if anyone's interested) but the
other is trickier.
I'm running OS X 10.5 with macpython 2.5, java 1.6.0_15, and GCC
4.0.1, although I get a very similar problem on Ubuntu 9.04 64 bit
with python 2.6 and GCC 4.3.3.
I'm using the following command line (obviously the lingpipe jar is
in the parent dir):
python -m jcc --jar ../lingpipe-3.8.2.jar --build --python lingpipe
--version 3.8.2 --files 4 --exclude com.aliasi.xml.XHtmlWriter
Things go fine apart from a few warnings until it dies with the
following:
/Library/Python/2.5/site-packages/JCC-2.4-py2.5-macosx-10.5-i386.egg/

I can build PyLucene fine on both test systems.
Does anyone have any idea what's going on here?
Someone reported a similar error recently with the same
get_iterator_next template. I wasn't able to reproduce it, though.
Maybe a way to sidestep the problem -or to get a better clue as to
what the bug is - would be to try to use JCC from svn trunk. This
template has changed there.
Another thing to try could be to increase the number of files to
generate thus generating smaller ones and then maybe avoiding some
compiler limit that may be triggering this.
Of course, there is also the possibility of a JCC bug that, for
example, could be leaving out a required header file. The way to test
for this condition is to generate one .cpp file per class via the "--
files separate" option and watch for errors. Come to think of it, this
is what I would try first.
