Issue with 10_6_X IB CMSSW_10_6_X_2025-02-02-0000

[Martin-Grunewald]

cmsRun fails for me on a SLC7 PC:

The error message is:

cmsRun RelVal_DigiL1Raw_GRun_MC.py
----- Begin Fatal Exception 02-Feb-2025 11:37:32 CET-----------------------
An exception of category 'PluginLibraryLoadError' occurred while

Last weeks IB ran fine. Any changes since then in the underlying build?

cms-sw/cmsdist#9658 fixes this. IBs and PR tests did not fail as libisal was picked up from our slc7 container [a] but now cms-sw/cmsdist#9658 explicitly deploys isal along with cmssw so libisal is picked up from our externals [b]

@Martin-Grunewald , this should be fixed [a] for CMSSW_10_6_X_2025-02-02-2300 and above . Can you please check this IB on slc7 node?

[Martin-Grunewald]

Yes, this IB works for me fine! Thank you for fixing this, @smuzaffar !
