Install instruction gives an error

[olalonde]

On Mac with Python 3, the pip install command doesn't work:

$ pip install git+https://github.com/src-d/kmcuda.git

I'm also getting a build error on mac when trying to compile:

This is weird because it works In Travis. The first error means that there is no setup.py in the root dir. Indeed, it is not after the latest refactoring, at the moment you have to change to src. The second error violates the condition stated in the Readme. Your clang does not support openmp. This has nothing to do with kmcuda, probably Homebrew screwed it up lately. Try to build a sample openmp prog using it.

Ah, I see. I will try to find a workaround. By the way, if the travis build works for OS X, it seems like it wouldn't be that hard to distribute the compiled module for macos as well?

Looks like llvm no longer has --with-clang option. After re-installing llvm, I'm getting a new error:

I tried disabling the openmp check in cmakelist:

And the command now finishes, but I'm later getting another problem:

Ok, so I think my Macbook Pro doesn't even have a CUDA compatible GPU :| Sorry to waste your time.

@olalonde I fixed the pip install cmdline so that the original issue is resolved. The solution is

pip3 install git+https://github.com/src-d/kmcuda.git#subdirectory=src
