Hey there I tired to compile a program using autotools. I realized that during the configure autotools is trying to compile "mpif77 -f77=gfortran -c -g conftest.f". The compilation fails with: configure:18975: mpif77 -f77=gfortran -c -g conftest.f >&5 gfortran: error: unrecognized command line option '-f77=gfortran' configure:18975: $? = 1 configure: failed program was: | program main | | end configure:18983: result: no witch leads the whole configure to fail. I tried to compile the sample program on the command line unsing "mpif77 -f77=gfortran test.f" and I got the same result (test.f containing just "program main \n \n end"). According to the man page of MPICH v3.2 "-f77" should choose the used Fortran compiler? It looks like the option is passed to fortran itself? I tried it with MPICH v3.2 as well as with the latest version form the git. MPICH 3.1 is working fine. Has there something changed between MPICH 3.1 and 3.2? Best Andreas -- M.Sc.
