Hi,
Im using pycuda on arch linux with CUDA 4 and have had problems with the
gcc 4.4 requirement (with arch using gcc-4.6 as default and providing
gcc-4.4 as a separate package).
I am aware of many possible solutions (which all work for me) but it
would be quite nice to change the gcc that nvcc uses via 'nvcc
-ccbin=/usr/bin/gcc-4.4' etc. You can obviously pass this to the compile
function in the wrapper but it would be nice to be able to add some
options at install time (via configure.py etc.) so a PKGBUILD can
configure pycuda to 'work out the box'.
Im not sure if this is already possible or if it would be feasible?
This is not yet possible, but it's easy to patch in. Here's how to do
it: Add a string config option for that to configure.py, defaulting to
just 'nvcc'. Before setup.py call the distutils setup() function, write
pycuda/config.py with the configured value. Add pycuda/config.py to
.gitignore. In pycuda/compiler.py, read the default compiler from that
setting. Test that everything works. Submit patch. :)
HTH,
Andreas
