If it helps, my system specs are:

OS: OSX 10.14.2
Python: 3.6.2

Thank you for letting us know. We have just successfully tested installing on mac, but with different OS and python version. We will look into this and keep you updated.

Could you check what version of the Command Line Tools you currently have, and try updating them (see e.g. https://stackoverflow.com/questions/42538171/xcode-command-line-tools-how-to-update). If this does not help, let us know.

Hi @lauri-codes I have Command Line Tools 10.1

Hi @ardunn,

It seems that the issue actually comes from the newer version of Command Line Tools. At least with CLT version 9.4.1 there is no issue. We will try to resolve the issue, in the meantime downgrading CLT should help.

Hi @ardunn,

Could you check if the problem is now fixed in the git master branch or in the newest pypi version (dscribe 0.1.8). I did manage to install everything under OSX 10.13.6, Python 2.7 and CLT: 10.1.

The problems seems to be in the compilation flags distutils uses when compiling the C++ extension included with DSCribe. Newer versions of CLT come with clang that does not support the "-std=c++11" flag used in setup.py. Instead something like "-std=libc++" should be used. I now added the extra compilation argument "-mmacosx-version-min=10.9" which seems to force backwards compatibility with the old flag.

Hi @ardunn,

Did you have time to test if the setup now works in your environment?

Closing this issue for now.

@lauri-codes sorry forgot to respond to this. Yep, pip install works now! Thanks
