Hello, I am a Newbee here,

my system iss a 64bit gnome Backtrack 5 R2

I tried to install Nvidia Cuda drivers for pyrit. by taking some tutorials like this -> http://chee-yang.blogspot.de/2011/11/backtrack-5-accelerate-pyrit-with.html

all works fine until, at the point of the "Setup CUDA for Pyrit" by typing : "python setup.py build"

i have these lines.

root@bt:~/pyrit/cpyrit_cuda# python setup.py build running build running build_ext Compiling CUDA module using nvcc 4.2, V0.2.1221...
