I'd like to run Open MPI on a cluster of RISC-V machines. These machines are pretty weak cores and so I need to cross-compile. I'd like to do this:
Machine 1, which is x86_64-linux-gnu, compiles programs for machine 2. Machine 2, which is riscv64-unknown-linux, will run these programs. It seems to me like the correct configure line for this might be: ./configure --host=riscv64-unknown-linux --target=x86_64-linux-gnu --enable-static --disable-shared --prefix=/home/ubuntu/src/ben-build/openmpi However, this yields an error: configure: WARNING: *** The Open MPI configure script does not support --program-prefix, --program-suffix or --program-transform-name. Users are recommended to instead use --prefix with a unique directory and make symbolic links as desired for renaming. configure: error: *** Cannot continue Any tips? Will it be possible for me to cross-compile this way with Open MPI? Ben
