Support clang on OS X 10.9

[seibert]

On OS X 10.9, clang is the only compiler shipped with XCode. Clang doesn't yet support OpenMP, so it might make sense to disable OpenMP backend was disabled when clang was detected. I'm also seeing various warnings or errors about compiler options for some examples, like invalid argument '-bundle' not allowed with '-dynamiclib'.

If I manually switch to the CUDA backend, I see the error ld: unknown option: -Wl, followed by the stack trace:

eriv(Rosenbrock):
Traceback (most recent call last):
  File "rosenbrock.py", line 25, in <module>
    print "Deriv(Rosenbrock):", rosenbrock_derivative(x)
  File "/work/mobi/parakeet/parakeet/frontend/decorators.py", line 20, in __call__
    return run_python_fn(self.f, args, kwargs, backend = backend_name)

  File "/work/mobi/parakeet/parakeet/cuda_backend/run_function.py", line 17, in run
    compiled_fn = CudaCompiler().compile_entry(fn)

    linker_flag_prefix = self.linker_flag_prefix)
  File "/work/mobi/parakeet/parakeet/c_backend/compile_util.py", line 271, in compile_module_from_source
    if not compiler_is_gnu(compiler):
  File "/work/mobi/parakeet/parakeet/c_backend/compile_util.py", line 209, in compiler_is_gnu
    return (compiler.endswith("gcc") or
AttributeError: 'list' object has no attribute 'endswith'

I am going to try installing gcc 4.8 next to see if that solves these problems.

Hi Stan,

I'm going to disable clang as a compiler option until I have some way to
integrate it into regular testing. For now it was just a longshot "if all
else fails..."

Also, thanks for reporting the bug in "compiler_is_gnu", it will be fixed
in the next release.

Hi I am actually not sure if this is related, but on my Mac (OSX 10.9) I get compilation errors (for instance during test/compiler/test_optimizations.py)

I have checked the closed issue: "NPY_ARRAY_OWNDATA error", but I don't seem to have a double numpy installation, I am however using clang as compiler... Is this a no go for now?

          PyArray_CLEARFLAGS(fresh_array, NPY_ARRAY_OWNDATA);

Hey Gerdus,

Sorry I don't yet have a better way to check multi-platform compile bugs. Do you mind seeing if the latest release works for you?

Thanks,
Alex
