All,
I took this discussion off line since it's now not relevant to openmpi
directly, but since I started it to get a truly 64 bit ATLAS lib
under leopard you need to configure it with the -b 64 -Fa ac "-L/usr/
local/lib/x86_64 -m64"
Doing otherwise will not lead to a 64-bit file.

Linwei,
It looks like you are getting a mix of 32 and 64 bit code (hence the
'file is not of required architecture' error). Are you using the
command line flag -m64 for some parts of the build and not for
others. You need to use either -m32 or -m64 for all the builds.

Dear sir,
Thanks very much for your detailed guideline~
I'm now trying to follow it out~
I've installed gcc 4.3 & openmpi~
When compiling CLAPACK, I'm trying to use the optimized BLAS
library by ATLAS, so I set the BLASLIB in the make.inc as:
BLASLIB = ../../libcblaswr.a -lcblas
Points to clarify if I may, having gone through this relatively
recently:
g77 and gfortran are NOT one and the same.
gfortran from sourceforge works well, but it is based on gnu gcc 4.3
and not on the gnu gcc 4.0.1 that comes with Leopard.
Your best bet is to download the ENTIRE gcc package fr
Thanks, Jeff, I finally choose to use the ScaLAPACK installer provided
on the website~
with gcc/gfortran and openmpi...it is installed successfully but I
haven't tested the applications..
Thanks for your help.

FWIW, I'm not a fortran expert, but if you built your Fortran
libraries with g77 and then tried to link against them with gfortran,
you might run into problems.
My advice would be to use a single fortran compiler for building
everything: Open MPI, your libraries, your apps. I prefer gfortr
Dear Reeder,
It does not work. I do think they are from the fortran programs
I'm using (they are files included from the BLACS installation
package, not written by my own.
The thing is last time when I was using g77, it caused no problem...
thanks for your help.

Linwei,
Have you tried using -funderscoring with gfortran. I don't think the
trouble you are having is caused by having g77 and gfortran both
installed.
Do you know where the unreferenced symbols (_s_wsle, _e_wsle, etc )
are supposed to be coming from. If they are in your fortran programs
Dear Reeder,
I've tried add gfortran flag "-fno-underscoring", but the same
errors persist...
Is that possible because that I have both g77 and gfortran in my
computer?
Best,

Linwei,
Is there a problem with trailing underscores. Are you linking c/c++
files with fortran. Do the _s_wsle family members need to have a
trailing underscore
where are the unrefernced symbols supposed to be coming from. If they
have a trailing underscore in their names you probably nee
Dear Dr. Simon,
Do I need to remove g77 from my computer then? Since after installing
gfortran (for Leopard), there is some link problem with gfortran..
When I try to build some routines in the BLACS, it gives error like:
Undefined symbols:
"_s_wsle", referenced from:
_MAIN__ in tc_fC

g77 is outated. You have to switch to gfortran (it's descendant).
It should work, and will be far more efficient.
Be carefull to install a version consistent with your gcc.
Keep us in
Dear Dr. Simon,

Dear Doug,
Thanks very much. I installed the latest OpenMPI and BLACS. For
the ScaLAPACK, I had some problem related to
BLAS library. Since in mac, it is in the vecLib, I've no idea how to
set the BLASLIB in the SLmake.inc file for ScaLAPACK.
also, though compiling BLAS succeed, I'm no
Linwei,
mpif.h is the include file for fortran programs to use openmpi. The
apple version does not support fortran. If you want to use openmpi
from fortran you will need to install a version of openmpi that
supports fortran, this will install mpif.h. I suggest you install the
new version
Dear all,
I'm new to openmpi. I'm now trying to use BLACS and ScaLAPACK on
Leopard. Since it has built-in Open MPI, I didn't install any other
versions. I followed the BLACS install guidances in FAQ section, and
it generated errors as:
