Hi, Thanks a lot for your reply. But this (AC_LANG) is making make to crash. Copying your configure.ac, I am getting: $./configure checking for gfortran... gfortran checking whether the Fortran compiler works... yes checking for Fortran compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU Fortran compiler... yes checking whether gfortran accepts -g... yes checking for gfortran option to support OpenMP... -fopenmp OPENMP_FCFLAGS = -fopenmp configure: creating ./config.status $make Makefile:15: *** missing separator.
