So in this example you will probably also have symlink with version 1 and version in soname set also to 1. And others will link to version 1 and not 1.11 or 1.10 so both would potentially load with any SO user. If something needs new functions from 1.11 but there is 1.10 in the system it should probably be resolved/updated by the package manager? > > _______________________________________________ > Podofo-users mailing list > Podofo-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/podofo-users >
