Description Coacher 2013-03-17 07:14:48 UTC

I've tried to emerge yafu today, but failed. See build.log attached.

The error message there is about undefined reference to OpenMP functions, but I have openmp USE enabled globally and gcc and gmp-ecm are both built with openmp support. Maybe there is some link flag missing?

Reproducible: Always

Proposed patch that adds `-lgomp` to link flags. After it I was able to succesfully finish `make x86_64` build.
