Hi Robert,I created an issue for this in Mantis: http://public.kitware.com/Bug/view.php?id=14122
Best regards, Marcel Loose. On 01/05/13 15:09, Robert Maynard wrote:
It looks like you used the ubuntu cuda package which installs the cuda library to a directory that FindCUDA wasn't expecting. I think we can extend FindCUDA to also use x86_64-linux-gnu as a valid directory to search for libcuda. can you submit a bug on mantis for this, so it doesn't get forgotten?

Can you run CMake --debug-output output enable and see where findCuda is searching? On Mon, Apr 29, 2013 at 11:52 AM, Marcel Loose <lo...@astron.nl> wrote:Hi Robert, I agree that on the CentOS machine the install paths are non-standard. For the Ubuntu system, on the other hand, I have to disagree with that statement. It is a *standard* Ubuntu 12.10 system, so IMHO FindCUDA.cmake should be able to locate libcuda.so on that system.

On Mon, Apr 29, 2013 at 7:38 AM, Marcel Loose <lo...@astron.nl> wrote:Hi all, I noticed that FindCUDA.cmake fails to locate libcuda.so on at least two different platforms: Ubuntu 12.10 and CentOS 6.3 using Cluster Manager v5.2. I can persuade FindCUDA.cmake to search for this library by explicitly setting the environment variable CUDA_LIB_PATH, and then it finds it. However, IMHO, using this trick should only be necessary as a last resort. Is this a bug?
