it appears for mysqlc just a -DRTL_DISABLE_FAST_STRING is enough to get something that should run already on 3.6 too: > master > readelf --version-info > /work/lo/master/solver/unxlngx6/lib/mysqlc.uno.so | grep LIBO_UDK > 01c: a (LIBO_UDK_3.6) 4 (UDK_3_0_0) 2 (UDK_3_0_0) 4 (UDK_3_0_0) > 0x0050: Name: LIBO_UDK_3.6 Flags: none Version: 10 committed in 34faec549ef33f77c4f866a4094d9fcf447025ee there seems to be another C++ extension "Presentation Minimizer" but for that one it didn't help, it still needs LIBO_UDK_4.1 (but i think we bundle this "extension" so probably not much need to fix that). _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
