Hm, for some reason path for moc'ed file is not wrapped with quotes. You wrote makefile by yourself or generated it with qmake/cmake? If first doublcheck it for paths.

szh1

It is generated by Qmake.

DenisKormalev

can you post it here? maybe there are some problems.

DenisKormalev

oops, I meant .pro file :)

I don't see anything wrong with it. It built fine until today. I just moved the project to a different location on my hard drive.

I remember having this problem once, but I don't remember how I fixed it.

DenisKormalev

Try to remove .pro.user file at new location and open project again in QtCreator.

szh1

I tried that. Same.

szh1

I just uninstalled and reinstalled the Qt SDK, but it didn't change anything. I also tried copying the files again, even to a different place. It is still not building.

szh1

I created a new empty project, imported the old files, and now it's working!

Your Build directory path must not contain spaces.. In your case `C:/My Dropbox/Extreme Image Converter/ExtremeImageConverter-build-desktop’ contains spaces..

I know this is a very old post but I've just bumped into it. This could be helpful.
This kind of errors:
[debug/moc_mainwindow.cpp] Error 1
[debug/moc_*cpp] Error 1

might come when declaring class data members in the slots / signals section by mistake.

Remove your file from project (not permanently) than add again with "Add Existing Files"

In my case I've got the same error: I use enum members of 3.h file in 1.cpp file, the 3.h file wasn't included into 1.cpp file (and no warning from Qt Creator 12.3.1). Also, when I have the same enum in 1.h and in 3.h files and use it in 1.cpp file.
