Following the instructions in the readme I get the following output when running the tests:

I don't know much about cabal and how unit tests are typically set up in haskell. If you could give me some pointers on how to narrow this down I can try to fix.

Strange that no error message is printed.

  • What happens if you run the VectorAdd example?
  • The next thing to be printed should be "DEBUG: Adding finalizer to CommandQueue"
  • The DEBUG-prints are not inserted for all operations yet (sorry about that)
  • I have not tested it on a machine with more than one platform. I'm using GHC 7.8.3 and OpenCL 1.1 on a GeForce GTX 690, but no OpenCL is installed for the CPU. Might be something there.

Looks like there is some racy printing to cout going on but other than that this seems to work fine?

Which test is being run when I do cabal test? Perhaps I can try to walk through that test in ghci to get a better idea of what is failing.

That's because they are printed by the garbage collector, which runs concurrently, and yeah, not that useful.

I guess the failing tests are the ones in here:
https://github.com/HIPERFIT/hopencl/blob/master/tests/unit/HOpenCL/CommandQueue_Test.hs

The idea of the tests is to test the "createCommandQueue" command and property-functions for each platform and OpenCL device.

I suspect that VectorAdd works because it just selects the first available platform and the first available device for that platform:
