This replaces the asserts in execFromPlugin by fatal messages with the reason. - A failed dlopen of libO2G4Setup and friends stopped at assert(libHandle), without the error from dlerror(). - The message now gives the dlopen error, e.g. a missing static TLS reserve for Geant4 built with the initial-exec TLS model. - The library is opened once, with the platform suffix from DLLoaderBase.h. - A fair::FatalException follows the fatal message, since LOG(fatal) ends the process only when a fatal handler is installed. https://its.cern.ch/jira/browse/O2-7305 Co-Authored-By: Claude Opus 5.5 <[email protected]>

A failed dlopen of the engine setup library (
libO2G4Setupand friends) stopped atassert(libHandle), without saying why. The message now gives the dlopen error, for example when Geant4 is built with the initial-exec TLS model and the static TLS reserve is too small:The library is opened once, with the platform suffix from
DLLoaderBase.h. Afair::FatalExceptionfollows the fatal message, becauseLOG(fatal)ends the process only when a fatal handler is installed.https://its.cern.ch/jira/browse/O2-7305
