You would need to be more specific when talking about versions. I know that you were probably talking about names of Fedora packages but for CUDA exact gcc version matters. For example: CUDA 5.5 works with gcc 4.9, CUDA 5.0 required gcc 4.6, the same for CUDA 4.2. The 5.0 situation caused problems for Debian as CUDA required other gcc version that the one used to build NVIDIA kernel modules. > > - PyCuda builds and installs under python3 (using "python3 setup.py > build"), but then fails some tests.
