I found the problem. It is in the build process which passes -fdefault-real-8 (among other flags) to the compiler:
mpif90 -fdefault-real-8 foo.F90 ➜ mpirun -n 1 ./a.out 0.0000000000000000 0.0000000000000000 Cheers, Jan _______________________________________________ devel mailing list devel@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/devel
