sourceCpp does not work after updating R to 3.4.1

问题

I've just updated R from 3.3.1 to 3.4.1. Now I can't use the plugin sourceCpp() to source C++-code. When trying to source the function rcppfunc I get the error:

clang: error: unsupported option '-fopenmp' make: *** [rcppfunc.o] Error 1

Before updating everything worked as it should.

Has anyone else had similar C++-compiler issues with 3.4.1?

See the following post explaining how to resolve the -fomp error by enabling OpenMP compilations:

In particular, you can obtain the binary installer I made here:

This is based off of the pre-compiled clang4 binary available here:
