Locate CUDA installation on Linux

Question

What's the best way? Here are my solutions:

echo $PATH | sed "s/:/\n/g" | grep "cuda/bin" | sed "s/\/bin//g" |  head -n 1
which nvcc | sed "s/\/bin\/nvcc//"
which nvcc | head -c -10

They are all PATH-based. One could locate libraries instead. It would be more robust if there are no CUDA paths in PATH.

I'm using this in a Makefile.

Solution

How does something based onldconfig -p | grep libcuda sound ? Considering an appropriate ldconfig setup is explicitly advised at the end of the installation of the CUDA toolkit, it should do the trick without path nicely, I think.

So that's how one can obtain the pure path: "dirname dirname ldconfig -p | grep libcudart | awk '{print $4}' | head -n 1` | head -c -5". This is more robust than the PATH-based approach. However, it is working on a Linux box but not on a Mac. No ldconfig on MAC?

Oops, I should have asked: Locate CUDA installation path on Unix. For linux this is probably the best way.
