[mpich-discuss] g95 and mpich2 on new x86_64 MacOS 10.6 machine

[Robert Kerr]

Thanks everyone who helped me do this.  I now have working mpi versions
of everything I need.  Here are the suggestions I got and what I eventually
used.

I have only one question left, which is any recommendations on the proper
F90/F95 compiler to use.

Suggestions:
From:   Anthony Chan <chan at mcs.anl.gov>
Try setting FFLAGS=-m64 and F90FLAGS=-m64 as part of configure command.

From:   Pavan Balaji <balaji at mcs.anl.gov>
% ./configure F77=<64-bit_compiler> F90=<64-bit_compiler>

        From:   Dave Goodell <goodell at mcs.anl.gov>
I passed FFLAGS="-arch x86_64" F90FLAGS="-arch x86_64" to configure.
-m64 might work as well.

THIS is what got me there:
./configure F77=gfortran-4.2 FFLAGS='-arch x86_64' F90=gfortran-4.2
F90FLAGS='-arch x86_64' --prefix=/Users/kerrrobt/mpich2-install 2>&1 |
tee c.txt

The compiler I used was gotten from the following web site:
http://r.research.att.com/tools/
Go to: gfortran-4.2.3.dmg

I also downloaded a g95 compiler.  This was what I tried first.
It probably didn't work due to missing the FFLAGS/F90FLAGS, but
I haven't gone back to see if it would work with these flags set..

I got the g95 compiler from the web site: http://www.g95.org/downloads.shtml
where I downloaded at line x86 OSX by clicking on HTTP.

Any further recommendations on compilers?
