Building CLASS with CLANG-OMP (install.sh script)
For osx user it's possible to have clang with openmp (to do so you have to install clang-omp with homebrew see class install procedure ), but the file config/Makefile.config have to be modified : every occurance of -lgomp has to be replaced by -fopenmp .
This has to be kept in mind for the creation of a new installation script
