CUDA toolkit error for MAC: cannot open output file 'vectorAdd.o' :, Access denied

Question

I try to run the CUDA toolkit on a MAC, but when I compile the CUDA sample programs, I get this error:

cannot open output file 'vectorAdd.o': 'Error opening output file' vectorAdd.o ': Permission denied'

I checked the environment variables and driver installation, and everything seems to be OK.

Do you have any clue what might be the problem?

Thank!

If you copy the entire sample folder and its contents to your home directory, you can compile the samples without sudo.

( ), sudo. , samples :

sudo chown -R your-user-name /Developer/NVIDIA/CUDA-7.0/samples
