 building mpich1.2.7p1 with gcc4.0.2/gfortran

I am trying to install mpich1.2.7 on my box, and I want to use the
compiler I built from source myself (instead of using the /usr/bin/f77)

So, I configure in this way, but it seems that it failed to build mpif77
mpif90 (any fortran related mpi compiler). Any suggestion?

Please upgrade to at least gfortrn 4.1.1.  4.0.2 is
extremely brokenly.  I know for a fact that MPICH2
works fine with gfortran 4.2.0 (ie mainline) and it
should work with 4.1.1.

Thanks for the reply. First to follow the answer, do you think it's the
compiler's problem(instead  that I used a wrong configuration option?)
I guess I may not have used a correct configuration, for example, the
path of lib option "[-lib=LIBRARY] [-mpilibname=MPINAME] " looks quite
related to a non-standard configuration.

(see http://spin.magnet.fsu.edu/local/mpi_install/node4.html)

What makes me hesitate to try another version is: I tested some
functionality under this version for a while.

Regard,
Sean

Hi Sean,
the gfortran version doesn't make any difference. The problem is that
mpich configure fails to determine the way gfortran provides command
line arguments to f90 programs. What you have to do is:

export F77_GETARGDECL=" "

before running configure.
Hope it helps.

Alternatively, I would expect that:
configure F77_GETARGDECL=" " <other options>

would work as well, with the added benefit that the command line will
show up in the configure output.

Thanks a lot for the help!
It still does not work. Here I paste some log that I think may give some
hints--("cannot run Fortran 77 compiled programs.")

You should use F90, FC and CC environment variables to specify your
compilers instead of the -fc -f90 and -cc configure flags.

 building mpich1.2.7p1 with gcc4.0.2/gfortran
I was able to compile mpich1.2.7p1 with gcc4.0.3/gfortran with the
following

CC=gcc-4.0.3 -O2  (I don't know how "incorrect" it is to specify the
optimizations like this, but it works:))

CXX=g++-4.0.3 -O2

F90 = gfortran -ff2c  (I'm pretty sure you need the -ff2c flag)
FC = g77    (I think this is your problem, my would not work if I used
gfortran for the f77 compiler.  So I used the g77 found in gcc 3.x.x.

I also used the following options for config:
--enable-f90 --enable-f77 --enable-sharedlib

Hope this helps

Cheers

Hello - I had problems myself building mpich with gfortran, before I
found this nice thread. I want to add my experience, since it still
required some work until I found a working solution. I used the
following environment variables:

FC="gfortran-4.2 -O2 -ff2c -fno-underscoring"
F77_GETARGDECL=" "
CC="gcc-4.2 -O2"
CXX="g++-4.2 -O2"-
F90="gfortran-4.2 -O2 -ff2c -fno-underscoring"

I could compile mpich and run a F90 parallel code (after compiling it
with -ff2c -fno-underscoring).

Hope it helps,
Biagio
