Hi Warner -- sorry for the delay in replying; this one slipped by in
the holiday rush.
LAM requires that it be configured with the fortran compiler that
you're going to be using to compile applications.
This may not sound right, because you're clearly using a C++ linker to
compile your application below. But I'm guessing that you're mixing
several languages in the final application -- is that right? In this
case, LAM's mpic++ is not automatically linking in the fortran routines
(we only automatically link them when you use mpif77 -- is this why you
added "-llam..." manually? If so, the ordering doesn't look quite
right -- check "mpic++ -showme" for the correct ordering).
So I'm guessing from your output that LAM's fortran routines were
compiled with one fortran compiler, but the .o files in your link step
below contain at least some fortran objects that were compiled with a
different fortran compiler.
Does that help?
