I don't have the original posting, but if the problem was missing definition of some of the profiling routines, that's due to an EXTERNAL statement in mpif.h. The problem is fixed in the next release, due in January, but for now, you can configure as follows: configure -fc=pgf77 -f90=pgf90 -fflags=-My,124,0x1000 -f90flags=-My,124,0x1000 Also, if you're trying to use mpich compiled with g77, you should read the following: I use g77 to compile the objects in the MPI library. When I use pgf77 to compile and link against the MPI library, I see undefined references during the linking phase. The error messages are of the form: cavit.o (.data+0x170): undefined reference to mpi_send_ The g77 compiler appends an underscore to a global name and appends a second underscore if the name contains an underscore. For example, the routine 'mpi_send' will appear as 'mpi_send__' in the library. By default, pgf77 only appends a single underscore to global names. To direct pgf77 to append the second underscore, add the compile option -Mx,119,0x02000000 In the next release, this option will be named -Msecond_underscore Please send problems to trs@pgroup.com lfm Joachim Worringen writes: >hutch@my-dejanews.com wrote: >> >> I'm trying to install mpich on a redhat 5.1 system using the Portland Group >> fortran 77 compiler.
