Hi,


Thanks for the prompt reply. This might be basic but typically where is the 32 bit ofed libs? I think the default install prefix is /usr and my guess is the 64 bit libs is in /usr/lib64 . Where do I look for the 32 bit ofed libs? I remembered during the ofed build that passing 32 bit build argument failed - will it still install an OFED 32 bit libs?

You probably need to add --with-openib-libdir=/path/to/your/32/bit/ofed/libs.  I'm guessing that the system installed the 64 bit libs in the default location and the 32 bit libs in a different location.  If that's the case, then --with-openib-libdir will tell OMPI specifically where to look for those libs and use those instead.

Hi,


I've been trying to install openmpi 1.2.5 on my cluster system running RHEL 4 (x64) with OFED 1.3. I need openmpi 1.2.5 (32 bit) and OFED seems to only install 64 bit version. I tried to build OFED with 32 bit support but it failed so I figure it's best to just compile 32 bit openmpi. I followed the FAQ and few user experience on the web.

I ran this command:
./configure --prefix=/usr/mpi/gcc/32bit --with-openib=/usr CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 FCFLAGS=-m32

and after few scrolling lines, it stops here:

configure: error: Aborting.


What went wrong? From the error it says early OFED version which is not the one I'm using (running OFED 1.3 now).

Any advice is greatly appreciated.
