Jump to: navigation, search

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

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

I received this error, after making one tiny mistake: I named my headerfile mainwindow.hpp instead of mainwindow.h Once renamed, everything should work fine.

Tiny hint: if you quickly want to copy the source displayed in this tutorial, but are as annoyed as I am about the line numbering which is copied as well, use the edit function of this site to access the (barebone) sourcecode.
