Hmmm, to get a decent fortran compiler for my AlphaServers, I have to
compile my own GCC compiler set (the default with CentOS is not good
enough). Hence, I have gcc/g++/gfortran both in /opt/gcc/bin and /usr/bin.
I'd like to set CC=/opt/gcc/bin/gcc, FC=/opt/gcc/bin/gfortran etc. However,
instead I must do CC=gcc, FC=gfortran and manually let the path point
to /opt/gcc/bin such that it first searches in /opt/gcc/bin.
However, by default /opt/gcc/bin is not in my PATH, because in general
I'd like to use the original GCC compiler set that comes with the OS.
Then, what happens when I compile my MPI code "mpif90 mycode.f90"?
Does OpenMPI remember to use the compilers in /opt/gcc/bin, or will
it then erroneously use the ones in /usr/bin ?
Even better: is there a patch available to fix this in the 1.2.1 tarball, so that
I can set the full path again with CC?
(is it only the CC macro, or also F77, F90, CXX, CPP and CXXCPP?)
Thanks,
Rob.
