OsX error when installing: OpenMP not currently supported with the clang compiler! #37

Open davidbp opened 8 years ago

davidbp commented 8 years ago

Hello again,

I was trying to install pyviennacl by cloning the git repo and then follow the instructions.

When I write python setup.py build

I get the following...

NB: OpenMP not currently supported with the clang compiler!

Please delete siteconf.py and run ./configure.py --no-use-openmp After that your build via python setup.py build should work.

Hello Karl,

I'm sorry for writing so much! It's a pity the last version is not available with pip install, installing with pip was super easy.

Now I get the following error:

Hmm, the compilation error is weird, because it indicates that the output file cannot be written (yet the return value is zero??). Could you please try switching to Clang via

export CC=clang
export CXX=clang++
./configure --no-use-openmp
python setup.py build

you may also try to create the destination folder, maybe that helps:

mkdir build/temp.macosx-10.5-x86_64-2.7/src/_viennacl/
