Subject: Re: [OMPI users] configure:25579: error: No atomic primitives available for ppc74xx-linux-gnu

Thanks so much..

I only had to use --disable-mpi-f77 and --disable-mpi-f90 in addition to
the --host=powerpc-unknown-linux-gnu to have configure work
successfully. Ie.

/home/MPI/openmpi-1.2.6/configure
--prefix=/home/MPI/openmpi-1.2.6-install-7
448 --host=powerpc-unknown-linux-gnu --disable-mpi-f77 --disable-mpi-f90

--host should be formated in the output of config.guess, which would be
something along the lines of processor family-vendor-os. Note that
processor family gets lumped together in pretty large chunks. I'm
guessing that if you could run config.guess on your machine (it requires
a working compiler in some instances), you'd find it would return
something
like: powerpc-unknown-linux-gnu. If you pass that as --host, I'm pretty
sure you'll get what you need. If your cross-compilers are named
ppc74xx-linux-gcc, you'll have to then set CC, CXX, FC, and F77
explicitly.
