Apart from post-COVID syndrome there were some other setbacks lately, but those were mostly software-centered. Like the fact that I can not build a 32bit Chromium package for instance.
But also the realization that the latest LibreOffice 24.2.0 can no longer be compiled on Slackware 15.0 – its gcc 11.2.0 compiler is considered “too old”.
With the help and insight of Pat Volkerding I was able to compile LibreOffice on Slackware 15.0 anyhow:

I need to test the resulting binaries, and I still need to see whether I can repeat this on 32bit Slackware of course… but it looks promising.
More to follow.

Update 2024-Feb-21:

Wed Feb 21 12:41:50 UTC 2024
libreoffice: updated to 24.2.0 for Slackware 15.0 and -current.
Depends on openjdk17.
openjdk17: added v17.0.10_7 for Slackware 15.0 and newer.
Only install one version of Java!

Cheers, Eric
