Benjamin,
unfortunatly, the compiler wrappers (mpicc and friends) will be riscv64
binaries.
fwiw, they will (try to) use the cross compilers on the riscv64 machines (!)
but you can configure with the '--enable-script-wrapper-compilers'
option in order to generate scripts
that can be invo
Yeah, I just noticed that Open MPI was giving me all x86_64 binaries with
the configuration flags
./configure --host=riscv64-unknown-linux --enable-static --disable-shared
--disable-dlopen --enable-mca-no-build=patcher-overwrite
--prefix=/home/ubuntu/src/ben-build/openmpi
and was very confused.
Benjamin,
i noticed you build Open MPI with plain gcc.
is gcc a cross compiler ?
if not, you have to tell configure to use the cross compilers (and cross
assembler and linker too)
for example
configure CC=crosscompiler ...
you might be able to achieve this with standard gcc and the right
There is something odd here.
From the configure.m4 of patcher/overwrite
#if !defined(__i386__) && !defined(__x86_64__) && !defined(__PPC__)
#error "platform not supported"
#endif
My guess is that should fail on your arch.
Can you please compress and post your config.log ?
Meanwhile, you can tr
I have the same error with

With the configure line
./configure --host=riscv64-unknown-linux --enable-static --disable-shared
--prefix=/home/ubuntu/src/ben-build/openmpi
It successfully configures, but I now get the error

Benjamin,
try removing the --target option.
if it still does not work, then try replacing --target with --build
you can refer to

for the details
As far as Open MPI is concerned, note you cannot cross build Fo
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 seem
