Greetings all,

I downloaded and configured v1.2.2 this morning on an Opteron cluster using the following configure directives...

./configure --prefix=/share/apps CC=gcc CXX=g++ F77=g77 FC=gfortran CFLAGS=-m64 CXXFLAGS=-m64 FFLAGS=-m64 FCFLAGS=-m64

Compilation seemed to go OK and there IS an mpif90 option in /bin......but it gives me the following error when I try to compile my source file:

/share/apps/bin/mpif90 -c -I/share/apps/include -O3 ft.f
Unfortunately, this installation of Open MPI was not compiled with
Fortran 90 support.  As such, the mpif90 compiler is non-functional.

I am certain that gfortran is installed and working correctly as I tested compilation of a small piece of serial code with it.

Something I am doing wrong?
