[Pyode-user] libode.dylib linking issue on macosx + darwinports

[Casey D. <cas...@gm...>]

I had a problem using pyode (from cvs) on MacOS X using python
2.4 and ode 0.7 installed via darwinports. The setup.py was able to
build and install pyode successfully, but I could not import ode:

>>> import ode
Traceback (most recent call last):
 File "<stdin>", line 1, in ?
ImportError: Failure linking new module:
/opt/local/lib/python2.4/site-packages/ode.so: Library not loaded:
libode.dylib  Referenced from:
/opt/local/lib/python2.4/site-packages/ode.so
 Reason: image not found

Looking at the ode.so in site-packages shows that libode.dylib was
linked in with a relative path:

% otool -L /opt/local/lib/python2.4/site-packages/ode.so
/opt/local/lib/python2.4/site-packages/ode.so:
       libode.dylib (compatibility version 0.0.0, current version 0.0.0)
       /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0,
current version 7.4.0)
       /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current
version 1.0.0)
       /usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.3.4)

If I diddled PYLD_LIBRARY_PATH, I could get ode to import, but it
broke other things in the process. Ultimately I was able to fix it be
changing the link to libode.dylib to an absolute path.

% sudo install_name_tool -change libode.dylib
/opt/local/lib/libode.dylib
/opt/local/lib/python2.4/site-packages/ode.so

I'm not sure the best way to fixup setup.py et al to do this
automagically (i.e., just prevent the unqualified link in the first
place). If you do great, if not I can do some more digging and figure
it out.

Ideally pyode would have a darwinport itself, though you'll need to
release what's in cvs first for that to be practical ;^)

Out of curiousity what is the state of the version in cvs? How close
to stable/release ready would you consider it?

Thanks much for this package, I'm a newbie to ode but it looks like a
great tool.
