Compiling failed due to 'undefined reference to vtable ...'

When compiling, cmake failed during the linking process. undefined reference to `vtable for MainWindow'

Simply add the following line to the mainwindow.cpp:

  1. include "mainwindow.moc"

Also add this line to your CMakeLists.txt near the top: include (KDE4Defaults)

I don't exactly know why this happens to me, but I suspect the fact that I have not built any special environment for working on KDE4 applications (as described here.

Can someone who understands the process please add the appropriate steps to the main tutorial?
