Here's the one I built the other day if you want to test. Not sure of the actual version besides it being the latest.
Edit: Is there an ICU legacy package?
There is libicu-legacy.4.2.1-2.oc00.i686, but that's by all accounts a fairly old thing.
Re: the build you provided, deployed it in a running system (so no reboot, but I did the 'repmod -u' thing), OO started up fine, but then died when I sylected the About dialog...I was just poking here and there to see if standard functionality was good.
Here is what I found in POPUPLOG.OS2:
03-26-2026 20:59:41 SYS2070 PID 01e6 TID 0001 Slot 0131
G:\APPS\GENERAL\OPENOFFICE417\PROGRAM\SOFFICE.BIN
I18NPOOL->ICUUC.__ZN3icu22RuleBasedBreakIterator5resetEv
127
I'll re-try following a reboot as there may always be some other DLL dependancy thing that's playing havoc here.
Thank you, as always!
