Hello All,
I'm very excited to use PyCuda and have been struggling to get it
working. Finally I have 0.92 compiled (0.93 doesn't compile at all for
me) and installed but the tests do not seem to work. I've read the
mailing list archive a few times but may have overlooked the answer to
this.
Jan Acosta had a similar problem with getting test_driver.py to work.
The solution for him was to add the proper boost library path (one in
his home directory) to LD_LIBRARY_PATH. The output of ldd shows it is
pointing to my local installation of boost-1.38.
J-Pascal suggested using the version of boost that comes with the
distribution. I'm using the latest Mint which is based on Ubuntu 8.10.
The libboost-python-dev in the repos is 1.34, but the pycuda main site
says to use 1.35 or greater, so I rolled my own.
I compiled pycida-0.92 with the CXXFLAGS option as described in the
FAQ because i am using gcc41 since CUDA 2.1 seems to have some trouble
with gcc43.
I am fairly sure the cuda sdk and toolkit are installed properly since
the demos that come with cuda work fine.
Below is output from test_driver.py, ldd, my LD_LIBRARY_PATH, and
proof nvcc is found and in the path.
Sorry for the length of the email. Just trying to cover the bases
discussed in previous install problem emails. I wouldn't be too
surprised if it's some sort of a config issue, but I've been at this
for a few days now and can't seem to find the solution. Maybe somebody
knows what's up? Any help will be appreciated.
Best Regards,
Rayjan
