If you run into troubles, it is always a good habit to report the following information:

the way build.mrcc was invoked
the output of build.mrcc
compiler version (for example: ifort -V, gfortran -v)
blas/lapack versions
as well as gcc and glibc versions

as well as the value of the relevant environmental variables, such OMP_NUM_THREADS, etc.

This information helps us a lot when figuring out what is going on with your compilation

Possible bug in build.mrcc spoils OMP build was created by SBehnle

Dear MRCC support team,
there is probably an error in the file "mrcc.build" of the latest release (2017-04-12). In line 714, the variable $ompopt is missing, hence the linking step of dmrcc fails as the linker doesn't find the OpenMP library. After adding $ompopt, the build succeeds (although i can't see dmrcc spawning threads)

Dear Prof. Kallay,
Thank you for the quick answer.
i used the GCC 7.2.0 suite.
The build command was "build.mrcc GNU -d -pOMP"
