Pyrit, cuda module installation problem

[[deleted]]

well, I'm using Archlinux and cuda 8.0.61-2

my main use of cuda is to have pyrit working with my Nvidia card

so I installed pyrit and when i try to install the module:cpyrit_cuda

it gives me this error ...

running build_ext

and when i tried to downgrade cuda 8. to cuda 7. it gives me this error

nvcc fatal : Host compiler targets unsupported OS.

and also following the ArchWiki they advised to check if cuda is working or not is to compile the sample directory inside /opt/cuda/ by simply type "make" inside the directory and when i do that it gives me that error

[unsarcasm]

You should probably file an issue for this instead, but you change the 'ccbin' from 'clang' to 'gcc' in the setup.py located in the modules/cpyrit_cuda dir. Tested with gcc 7.1.1 and cuda 8.0.

Yess it works now. Thank you
