This is your build error:

/var/tmp/portage/media-libs/mesa-17.1.8/work/mesa-17.1.8/src/mesa/swrast/s_aatritemp.h:
In function 'rgba_aa_tri':
/var/tmp/portage/media-libs/mesa-17.1.8/work/mesa-17.1.8/src/mesa/swrast/s_aatritemp.h:196:57:
error: implicit declaration of function 'omp_get_thread_num'
[-Werror=implicit-function-declaration]
          span.array = SWRAST_CONTEXT(ctx)->SpanArrays +
omp_get_thread_num();

IIRC openmp provides that function. But his:


cc1: some warnings being treated as errors

mesa has 18 versions in-tree and mesa-17.1.8 is the second oldest. Any
special reason you are stuck so far back? A package.mask you no longr
actually need maybe? My first action would be to use something more
rcent that functions for yu.
