Ubuntu – nvcc compiler setup Ubuntu 12.04

cudanvidia

I successfully installed the nvidia driver and toolkit for cuda 5 (but not the samples) on a 64 bit Ubuntu 12.04 box. The samples failed to install even though I previously ran

sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev

I can't seem to find nvcc. I ran 

export LD_LIBRARY_PATH=/usr/local/cuda-5.0/lib:/usr/local/cuda-5.0/lib64:$LD_LIBRARY_PATH

nvcc -v reports that the compiler is not found: 

nvcc -V No command 'nvcc' found, did you mean:
 Command 'nvlc' from package 'vlc-nox' (universe)
nvcc: command not found

The getting started guide hasn't been of much help here.

What's going on here? Do I need to install the gpu computing sdk samples to get nvcc?

It looks like you installed nvcc but it's not in the executable path.

The libraries are located in /usr/local/cuda-5.0/lib and /usr/local/cuda-5.0/lib64, so the executables are probably located in /usr/local/cuda-5.0/bin. Check in that directory, to see if there is a file called nvcc. If so, add /usr/local/cuda-5.0/bin to your PATH environment variable.

If nvcc is not located there, search the entire /usr/local/cuda-5.0 directory. One way to do that is to run the command:

find /usr/local/cuda-5.0 -name nvcc

Once you find it, you can add the directory that contains it to your PATH variable, or you can make a symbolic link to it in a directory that's in your PATH, or you can invoke it by its full path name (e.g., /usr/local/cuda-5.0/someplace/nvcc).
