There are a couple examples in the source how to do this, for example src/kits/interface/Slider.cpp contains some binary compatibility exports. To get the proper mangled name, I usually try to launch an application that was linked against the old symbol and note the missing symbol that the runtime loader spits out. Best regards, -Stephan
