I use python setup.py install to install WMAP likelihood. Then I face the following error during the procedure.

It seems that I don't have libwlik file, but I don't where it is or how to create that.

Does anyone know this ?

Hi,

This is a MacOS problem (and not a MontePython problem). The problem seems to be with the clang compiler (in general, if you are using CLASS as well we do actually recommend switching to gcc instead of clang). Have you seen if this is something you can install via brew or anaconda? If not, I would see if switching to a different compiler solves the problem.
