Lots of errors in unmodified source, what's happening?

SPlatten

This morning I have rebuilt a project that has had no issues and now I'm getting lots of errors which I cannot explain:

In file included from ../clsQtSlider.cpp:7:
In file included from ../../XMLMPAM/clsQtSlider.h:45:
In file included from ../../XMLMPAM/clsMainWnd.h:286:

            1(o->*f)((*reinterpret_cast<typename RemoveRef<SignalArgs>::Type *>(arg[II+1]))...), ApplyReturnValue<R>(arg[0]);

What could explain this?

The backup I made of the source code yesterday which yesterday was building and even earlier this morning was working, now unzipped, does not compile and has the same errors....I've rebooted my system, same issue...why?

If I change the kit to 5.15, it compiles, if I change back to 5.14 if has the errors...I don't understand how this has broken.

Back up and running now....

@SPlatten said in Lots of errors in unmodified source, what's happening?:

/clsQtSlider.cpp:7:

What's at line 7 in that file?
Did you update your compiler in the meantime?

SPlatten

@sierdzio , starting at the top is just shows where headers are included until you get to the bottom where the actually error is, so in the case of my file:

clsQtSlider.cpp

/**
 * File:    clsQtSlider.cpp
 * Notes:   Contains implementation of the overriden signal/slot
 *          helper class for the QSlider control

 */
#include <clsQtSlider.h> //This is line 7

clsQtSlider.h

/**

 * This class overrides the Qt control class QSlider and provides additional

The rest are Qt files.

@sierdzio , I'm doing a Qt update now...deleted Qt 5.14.2 and will reinstall.

sierdzio

Good move, that might help. Also, remember to completely remove build directory to have a clean state for the new build.

Back up and running now....

Nice! Happy coding
