Add unified API support and fix the build mechanism appropriately. #42

@9prady9 : Can you test opencl on linux? For some reason my linux box isn't building libafopencl. It should work as expected though. It does work fine on OSX though :)

fixes #29

…so add a unified example

9prady9 · 2015-10-22T13:06:25Z

src/defines.rs

This enum's value in ArrayFire is 4, this is probably the reason OpenCL is not working. ArrayFIre OpenCL libs will be built but i believe it can't be used if this value is not 4 since ArrayFire's native enum has 4 for this backend.

This was a recent change actually which is probably why it is not working.

arrayfire/arrayfire#1064

9prady9 · 2015-10-22T13:16:18Z

On my home laptop(Linux), only CPU and ~~Linux~~ OpenCL backends ran fine in the unified example. haven't digged down yet, will post here once i have more information.

jramapuram · 2015-10-22T13:26:06Z

Try now, should work. What is 'linux' backend?

9prady9 · 2015-10-22T15:00:40Z

@jramapuram My bad, instead of OpenCL i wrote linux.

jramapuram · 2015-10-22T15:04:40Z

@9prady9 : no worries. Can you pull latest changes & try with:

> git submodule update --init
> rm -rf arrayfire/build

9prady9 · 2015-10-22T15:16:42Z

I did these also after the commands you pasted and it worked fine on my office machine (doesn't have CUDA though). I will have to test CUDA on another machine or later from my laptop.

@9prady9 : added the new function as well fyi

9prady9 · 2015-10-23T12:44:38Z

@jramapuram I have tested on my laptop with cuda device, CUDA backend still doesn't work for me in the unified example. CPU and OpenCL are running fine though.

jramapuram · 2015-10-23T12:48:17Z

@9prady9 : Hmm, not sure what is going on. It is working fine for me on linux and osx. Couple things:

Is your sdk_lib_dir in build.conf specified correctly? It might be lib64 or lib based on your OS
Is your cuda_sdk specified correctly?
Is your LD_LIBRARY_PATH pointing to the correct location of the new libafcuda.so ?
Is there a libafcuda.so in arrayfire/build/package/lib ?

9prady9 · 2015-10-23T13:53:17Z

Sdk path may be the reason, will check it out. I would assume cmkae will
pick Cuda sdk paths from standard location but in any case will check it
out.
