Neil,
If that does not work, please compress and post your config.log
There used to be an issue with raspberry pi3 which is detected as an
ARMv8 processor but the raspbian compilers only generate
ARMv6 compatible binaries.
If such an issue occurs, you might want to
configure CFLAGS=-march=armv6 LDFLAGS=-march=armv6
and try again
FWIW, I run openSuSE Leap for aarch64 (e.g. native ARMv8 processor) and
have no issue building/using Open MPI
Cheers,
Gilles

If your Linux distro does not have an Open MPI package readily available, you
can build Open MPI from source for an RPi fairly easily. Something like this
(not tested on an RPi / YMMV):
wget https://download.open-mpi.org/release/open-mpi/v3.1/openmpi-3.1.0.tar.bz2
tar xf openmpi-3.1.0.tar.bz2
cd openmpi-3.1.0
./configure |& tee config.out
make -j |& tee make.out
sudo make install |& tee install.out
This will download, configure, build, and install Open MPI into the /usr/local
tree.
You can optionally specify a prefix to have it install elsewhere, e.g.:
./configure --prefix=/path/to/where/you/want/it/to/install |& tee config.out
Then do the make/sudo make again.

I am starting to build a Raspberry pi cluster with MPI and I want to use the
latest Raspian Streach Lite version from the raspberrypi.org website. After a
lot of trials of watching youtubes on how to do this, I have found that the new
version of Raspian Streach LITE is not compatible . I am looking for details
instructions on how to install MPIwith this latest version of Raspian Streach
Lite. I am using the newset hardware,RPI 3 B+ which requires this OS to use the
features on the -new chipset
Thanks
Neil
