Also, btw using these two values and make clean, I was able to both
configure and build Open MPI properly. After that I compiled an example
code with -m32 flag and it compiled properly too :D. It remains to be seen
whether my setup of machines run them properly or not.

Ralph, well my --host flag contains i686-pc-linux-gnu and so does --build.

The problem is that you set the build and the host to the -same- architecture -
that indicates it isn't a cross-compile situation. The --host flag should
indicate the arch of the machines that will run the code - in your case, that
would be i386-pc-linux-gnu

Make sure to "make clean", too -- just to clean up any kruft that may be left
over from a prior build that is not necessarily compatible with your new set of
configure/build/link options.

I think you are missing the --host flag, so it still thinks it is building for
the current machine.

I also tried by adding
--host=i686-pc-linux-gnu
alongwith the --build option. Same error :(

Ralph,
As you suggested, I configured with the following options -
./configure --prefix=/home/wolf/openmpi/ CFLAGS=-m32 CXXFLAGS=-m32
FFLAGS=-m32 FCFLAGS=-m32 --build=i686-pc-linux-gnu LDFLAGS=-m32
I'm afraid I am still getting the same error messages while making as I did
last time. Did I
Do ./configure --help and you'll see options for specifying the host and build
target. You need to do that when cross-compiling.
