SOS:undefined reference to `vtable for<class name>

@qazaq408 said in SOS:undefined reference to `vtable for<class name>:

I guess that's is the point, MOC tools can't prduce moc*.cpp file

Then please do clean all build artefacts, and then compile your project. Paste the compile log here for analysis.

PS: Also make sure that there are no Makefile, *.moc, *.o and other generated files in your source directory! This will lead to the strangest effects possible.

@aha_1980
I had done this....
even I cpoy these three file (Moctst.h,MocTest.cpp,Main.cpp) to another dir,like E:/tk

and use cmd.exe
/////
e:
cd ./tk
moc MocTest.h -o Moc_MocTest.cpp

the system tell me .E:\tk\MocTest.h:1: Note: No relevant classes found. No output generated....
