Hi,
We routinely build OpenMPI on x86_64-pc-linux-gnu machines from
the sources using gcc and usually everything works fine.
In one case we recently installed Fedora 34 from scratch on an
ASUS G53SX notebook (Intel Core i7-2630QM CPU 2.00GHz ×4 cores,
without any IB device). Next we build
ut of the box anymore.

Hi there,
I already overcame this problem: simply using the gcc version (GCC)
13.2.1 that
comes with the Fedora 39 distribution, the openmpi build is now fine again,
