Jeff,
Then you'll be happy to know I've been building OpenMPI for years and I
never had any complaints about your configure/build system. Of course,
I'm a pro who gets paid to build open-source software all day long, but
I have to say I've never had any issues with configure, make, or 'make
check' with any version of OpenMPI.
Keep up the great work!
Prentice

Woo hoo! I love getting emails like this. We actually spend quite a
bit of time in the design and implementation of the configure/build
system so that it will "just work" in a wide variety of situations.
Thanks!

Hi Lana
I’m a Open MPI newbie too, but I managed to build Open MPI 4.0.4
quite easily on Ubuntu 20.04 just following the instructions in
README/INSTALL in the top level source directory, namely:
mkdir build
cd build
../configure CFLAGS=“-O3” # My CFLAGS
make all
sudo make all
sudo make install
It just worked. My small cluster happily runs Open MPI over TCP/1GB
Ethernet.
The make install step installed everything into /usr/local. I did
forget to ldconfig initially, which confused me. Other than that it
just worked.
