gnu.mk file OPENMP, Undefined reference to `omp_get_ ...
Closed this issue · 2 comments
The mk_make script builds with:
(cd exec/${CONFIG}_${COMPILER} ; make -j 8 OPENMP=Y NETCDF=3 ${COMP} AVX=${AVX} ${BIT} NCEPLIBS="${NCEPLIBS}" -f Makefile_fv3)
which indicates the use of OPENMP=Y. However in the gnu.mk template file
https://github.com/NOAA-GFDL/SHiELD_build/blob/main/site/gnu.mk
it has the openmp flag commented out, for example:
FFLAGS_OPENMP = #-fopenmp
at:
Line 51 in d6581a4
Line 58 in d6581a4
Line 67 in d6581a4
This causes a series of compile-time errors of the type omp_get_ ...
At the moment I'm changing this using:
sed "s/#-fopenmp/-fopenmp/g" < ${BUILD_ROOT}/${TEMPLATE} > OUT \
&& mv OUT ${BUILD_ROOT}/${TEMPLATE}
and the model seems to compile successfully.
Is there a reason for removing the openmp flags?
I do not see any compilation errors associated with the lack of -fopenmp in the gnu.mk template. Regardless, it does make sense to activate it and a future PR will address it.
