what should i do.......help

KDevelop: 3.1.1

Can you post the infowidgetbase.cpp file ? (It should be in plugins/infowidget/)

This file gets generated, and for some reason the ktabwidget.h header doesn't get included. In infowidgetbase.cpp there should be a line like this at the top of the file :

#include <ktabwidget.h>

thanks very much
i added that to the top of the file then everythine was done
now i must say:it's perfect
