Re: [O-MPI devel] Back to 32bit on 64bit machines...

Actually, I think that mpicc is doing exactly the Right Thing. If you don't specify -m32, the underlying compiler is going to default to 64 bit builds (and libraries), so it naturally tries the /usr/lib64 stuff. But when you supply -m32, it knows that you want to do 32 bit builds and uses

FYI, this worked and OMPI compiled but mpicc tries to use the 64bit libraries. Doesn't appear that -m32 is being passed in the configure or whatever down into mpicc. Once I dropped -m32 on my mpicc I was able to do 32bit compiles using mpicc on a 64bit machine. Looks like there's definately

This looks like it *might* be a libtool problem -- it's picking up the /usr/lib64/libstdc++.so when you're compiling in 32 bit mode (and therefore barfing). Can you send the libtool command that immediately preceded this link line? As a workaround, you should be able to --disable-cxx to d
