Hello all, Following up on the above post. I've had pycuda working successfully on ubuntu 12.04 laptop using an Optimus card using Nvidia and Intel graphics cards.
I then upgraded to 14.04 but have subsequently found Bumblebee to be a bit broken and am now using nvidia-prime as the nvidia driver. Trying to keep everything tidy, I thought I'd install python-pycuda using apt-get and it was very pleasing to see all the cuda toolkit automagically install. Great work. I'm not too fussy about being on the latest cuda toolkit since I'm a bit of a hobbyist. However, I think I've determined that the opengl part of the python-pycuda package hasn't been enabled properly. Normally when you install pycuda from the tar package and run configure you need to pass the ---cuda-enable-gl option. I note in pycuda 2014 that has changed to --no-cuda-enable-gl I find on my machine I can import pycuda.driver as cuda_drv import pycuda.compiler as Source_module etc but I cannot import pycuda.gl I've downloaded the ubuntu source deb package with a view to recompiling to enable gl but I get so many compilation errors I thought it best to describe the issue on this mailing list. Reading the debian/rules it seems as though the --cuda-enable-gl is selected for so I'm not really sure where to proceed. A lot of modifications have been made to the ubuntu source package. I should add that code that doesn't rely on pycuda.gl compiles and runs fine. Thanks for all the packaging work. Cheers and regards, Chris O'Halloran
