4.1.6: test suite fails with `-Wincompatible-pointer-types`

[kloczek]

When is used aatest glibc snapshot and in $CFLAGS is passed -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 some pragmas in glibs headers turns some warnings into errors

Here is test output:

I am also trying to build the 4.1.6 SRPM on RHEL 10.0 and I am also seeing similar issues with opal_datatype_t

gcc (GCC) 14.2.1 20250110 (Red Hat 14.2.1-7)

Is there any easy workaround for this?

[ggouaillardet]

I was able to build Open MPI 4.1.8 on CentOS Stream 10.
Can you try this version instead?

[jsquyres]

@ggouaillardet beat me to it by just a few minutes. 😄

FWIW, I am able to build Open MPI 4.1.8 and 5.0.7 with the inbox gcc-toolset-14 RPM on Alma 9 with -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3.

That being said, make check fails with the described errors on v4.1.8. Especially since make check succeeds in these conditions in 5.0.7, it's unlikely that we'll fix this; the v4.1.x series is in maintenance mode -- we'll only do work on v4.1.x if there's an urgent need. All of our effort is on v5.0.x and the upcoming v6.0.0 these days.
