The release notes for the latest version of LibreOffice (24.2) state that
"The minimum requirements for building and running LibreOffice on Linux have been raised from Red Hat Enterprise Linux 7/CentOS 7 to Red Hat Enterprise Linux 8/CentOS 8 (or equivalent)".
Since Red Hat/CentOS 8 does not have a 32-bit edition, I wonder if my problems compiling for 32-bit are due to a possible lack of support.
Tumbleweed Opensuse is 32 bit bleeding edge.
CWSIV Opensuse since 7.0 / 10.0 / 11.4 / 15.5 the last three are still on working machines.
