The fix is to change /usr/lib/python2.5/site-packages/aotcompile.py,
which doesn't put the right pathnames into the object files.
I've attached a patch. gbenson, please look this over. This is my
first ever Python hack, so You Have Been Warned. Input about my
(doubtless execrable) Python style welcome.
I have tested this patch on writer2latex, and I can debug it:
(gdb) b 'writer2latex.Application.main(java.lang.String[])void'
Function "writer2latex.Application.main(java.lang.String[])void" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
(gdb) r -jar /usr/share/java/writer2latex.jar
Starting program: /usr/bin/gij -jar /usr/share/java/writer2latex.jar
