Hi Gus:
 
Thank you for the advice.
But it still doesn't work. :(

Hi all:

I use the following command to configure a x86 version mpich2 on a x86_64
Linux Box (Feroda Core 10 x86_64)

./configure CFLAGS="-m32 -fPIC" CXXFLAGS="-m32 -fPIC" FFLAGS="-m32 -fPIC"
LDFLAGS="-m32" --enable-sharedlibs=gcc --enable-mpe --with-pm=smpd
--with-pmi-=smpd

The configure step is OK.

But when doing make, I get the following error...

/usr/bin/ld: i386 architecture of input file `.tmp/ibsendf.o' is
incompatible with i386:x86-64 output
...


Does anyone know the way to build x86 version mpich2 on x64 Linux Box ?
Thanks.



On Fedora 10 you have 2 options involving building rpms (I'm assuming
you know how to build rpms). Grab the MPICH2 rpm spec file for Fedora
10 from http://cvs.fedoraproject.org/viewvc/rpms/mpich2/F-10/, modify
the configure options to suit your needs, and then rebuild the source
rpm.
i. Install mock and then run; 'mock  -r  fedora-10-i386
--resultdir=./my-results  /path/to/your.mpich2.src.rpm'
ii. Run 'setarch i386 rpmbuild --rebuild /path/to/your.mpich2.src.rpm'
(Assuming you have all the right 32bit buildchain installed)

Option (i) is more likely to get the job done for you easily.

Cheers,
Deji

Hi Seifer

Two guesses.
Have you tried a "make distclean" before "configure"?
You may have leftover x86_64 object files from previous builds
hanging around.
You may need also F90FLAGS="-m32 -fPIC".

I hope this helps,
