× 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 :)

gfortran cannot compile xmrcc.f

this option does work for the build, but unfortunately this does not fix the problem with OpenMP, i.e., OMP_NUM_THREADS is not enforced in the GNU build (# cores always set to 1)

Please use -fallow-argument-mismatch instead. You don't necessarily want the legacy standard.

ah, you're exactly right. I also had to do this for compiling the Dirac program with gcc. I don't think this fixes my problem with OMP_NUM_THREADS however. I had to revert back to my older Intel compiler.
