Hi, I am in the process of installing Quantum espresso but, am experiencing issues compiling my OpenMPI. I get the error "configure: error: could not run a simple Fortran 77 program. Aborting."
Am using gcc-4.2.2 and OpenMPI-1.4.2 on CentOS-5.4. The configure instruction isssued appears as below: ./configure --prefix=/opt/openmpi/1.4.2 --with-tm=/opt/torque/2.5.1 CC=gcc CXX=g++ F77=gfortran FC=gfortran -- Regards, EDMUND OCHIENG'.
