libgpuarray test script fails

[folagit]

During the make process, I get the following warnings, which I assume result in some of the failed tests:

CMake Warning at src/CMakeLists.txt:159 (add_library):

  files in some directories may conflict with libraries in implicit
  directories:

I've tried suggestions to update $LD_LIBRARY_PATH and run ldconfig but this does not resolve the issue.

I am running Ubuntu 16.04, with CUDA 8.0, CUDANN 5.1.5. gcc and g++ all point to alternate versions suggested by theano install documentation.

Any help with this issue will be greatly appreciated.

thanks.

I think it is a duplicate of #247. We don't have time to work on the openCL back-end. Many things are missing. We need people outside our group to come and help finish it.

The CMake warnings have nothing to do with the failures and should be harmless. The problem with the tests is that you didn't specify GPUARRAY_TEST_DEVICE or DEVICE as an environment variable to specify on which device to test (or you did and it gets removed because of sudo).

Try running DEVICE=cuda0 make test

abergeron's suggestion helped to resolve this. Thank you.
