Both clang and gcc are installed. Any guidance how get it installed will be hugely appreciated.

bmoscon commented 6 years ago

the instructions are in the error message - use homebrew to install it: brew install llvm

Also, you can install from pypi and there are wheels on there for macOS

stnatter commented 6 years ago

I have llvm installed. conda install llvm. Not using homebrew.

bmoscon commented 6 years ago

then you cannt build from source. Please install the wheel from pypi

stnatter commented 6 years ago

tried: 'pip install clang' which installed clang 5.0. resulting in the same error.

aflag commented 6 years ago

pip install clang will just install python bindings to clang. I think the problem is that you need the actual compiler.

stnatter commented 6 years ago

i do have Xcode installed.

bmoscon commented 6 years ago

you need to install the versions of g++ or clang provided by homebrew (which you can read more about here: https://brew.sh/) The versions that come with xcode do not support openMP and thus will not work. You can install arctic simply by running pip install arctic. This will pull the wheel from pypi and install it

stnatter commented 6 years ago

wow. that worked indeed. my conda was screwed. did a complete clean reinstall of conda earlier today and now pip install arctic worked. thanks soooo much for your patience and help. Much appreciated.
