[Pyode-user] pyode trimesh compile issues on Linux

[Christopher F. <chr...@gm...>]

Hello,

For some reason the Ubuntu 8.04 install package gives a segmentation
fault when using to use a trimesh. I tried installing from a source
package on the downloads page on Sourceforge. When I call
triMesh.getTriangle() in python it gives the following error:

python: /build/buildd/ode-0.9.dfsg/GIMPACT/src/gim_trimesh.cpp:183:
void gim_trimesh_locks_work_data(GIM_TRIMESH*): Assertion `res==0'
failed.
Aborted

So I decided to try building the wrapper from the latest CVS source.
Here is the output from setup.py. It seems to build fine despite a
couple of warnings.

INFO: <ode/ode.h> found in /usr/include
INFO: ode_trimesh.c is up to date
INFO: ode_notrimesh.c is up to date
INFO: Installing with trimesh support.

However when I import the file in python it gives the following error:
>>> import ode
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /usr/lib/python2.5/site-packages/ode.so: undefined
symbol: dWorldGetLinearDamping

Any ideas on where to begin? My simulation seems to work in Windows XP
without any problems but I really need to get it working in Linux.

Thanks,
Chris
