Hi Wood Lotz, I was able to build mpich2 with the absoft 10.1 compiler with following configure variables set: CC=gcc CXX=g++ F77=af77 F90=af90 and to compile/run simple MPI fortran 77 code fine. So it seems that U77 library isn't really needed to build mpich2, so I would think we could leave libU77.a out for users to link in by themselves. Can you confirm that ?
