Hi All:

I wasn't quite certain the appropriate list for this,  but hopefully this will be found as needed. I know I have seen for several packages where building from source has failed on the Mac because of an error from using "-f openmp" in the compile options,  because the clang on the Mac didn't have openmp.

Now there is an R compatible version of clang with  openmp,  see:


I just ran into this in trying to compile the latest version of the package "bssm".  Installing that version of clang solved the compilation errors.
