Subject: Re: [OMPI users] Compiling Open MPI with PGI compilers in 32-bit mode

Ethan,

I agree with Doug. Did you try to build for 64-bit in the same
directory? If so, you need to do a 'make clean' or 'make distclean'
before compiling for 32-bit.

Even if you didn't try to compile for 64-bit yourself, try doing 'make
clean' or 'make distclean'. ;)
