Hello.
After updating from ROOT 5.22 to 5.26 (5.27) my C++ application does not work any more.
When I try to run it I get the following error message:
dlopen error: /usr/local/lib/root/libGX11.so: undefined symbol: _ZNK9TVirtualX13GetFontAscentEv
Load Error: Failed to load Dynamic link library /usr/local/lib/root/libGX11.so
Error in TCint::AutoLoad: failure loading library libGX11.so for class TGX11
Error in TPluginHandler::SetupCallEnv: class TGX11 not found in plugin GX11
