Can you provide the output of "nm wsjtx.exe" too please? That should hopefully show the problem. Sounds like a name mangling issue. You should have something like this: 004d9b60 T __ZN13Configuration4impl27on_font_push_button_clickedEv C++ does horrid name mangling which can make tracing link problems like this a PITA. Fortunately there should be only one function with this name in here.
The hex number in ldd is the load address of the library..it may vary from run to run. I think you should be able to see the mapping in "cat /proc/<pid>/maps" -- it's not very useful or relevant since wsjtx is statically linked with its own functions.
