Hello,
i had installed cuda driver and pycuda on mac, it looks working ok after
testing it with tests in NVDIA installation guide.
when I try to run a mod = SourceModule ()
I run into this error which looks to have problems with nvcc compiler.
I cannot figure out where the problem may be.
I check PATH for finding nvcc and looks ok...
echo $PATH
/Developer/NVIDIA/CUDA-6.5/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin/ruby
echo $DYLD_LIBRARY_PATH
/Developer/NVIDIA/CUDA-6.5/lib:

*pytools.prefork.ExecError: error invoking 'nvcc --version': [Errno 20] Not

As example, I use:
mod = SourceModule("""
__global__ void process(char **dest, char **line)
{
int tID = threadIdx.x ;//+ blockIdx.x * blockDim.x;
dest[tID] = line[tID];
}
""")
from this example
