OK, same error, so I guess the -j4 flag was not the culprit.
I'll look further into it as I have time.
I tweaked my virtual machine and tried again to build kdebase. Attached is a log.
I did not use any -j process flags. Here are the header includes in my local menutab_impl.h:
========================================== #ifndef __menutab_impl_h__ #define __menutab_impl_h__
#include <stdlib.h> #include <tqlistview.h> #include <kpushbutton.h>
#include "menutab.h" ==========================================
As the last recommended change was to add include '<stdlib.h>' to menutab_impl.h, hopefully the build failing with an error in menutab_impl.cpp is easy to solve. The best I can gather is that MenuTab::connect hasn't been defined, but I don't know how to repair.
