Sorry for the delay in replying.
This looks like a problem on your system -- I think Doug is right:
your system seems to be picking the wrong libraries when you specify -
m32. Can you compile any C++ libraries/binaries with -m32 successfully?

Hi,
OS: SLES10 SP1
OFED: 1.3
openmpi: 1.2 1.2.5 1.2.6
compilers: gcc g++ gfortran
I am creating a 32-bit build of openmpi on an Infiniband cluster,
and the compilation gets stuck, If I use the /usr/lib64/gcc/x86_64-
suse-linux/4.1.2/32/libstdc++.so library manually it compiles that
piece of code. I was wandering if anyone else has had this problem.
Or is there any other way of getting this to work. I feel that there
may be something very silly here that I have missed out. but I can't
seem to gather it.
I have also tried this on a fresh install of OFED 1.3 with openmpi
1.2.6
