QT Creator doesn`t create main.moc.

[Zlatomir]

Thank you very much. It works. Question is : Why QT creators didn`t include it like you?

Because it should work without specification of the path to that file, on linux it works, on windows it worked when the generated files where in the project folder, i guess that the mingw compiler search for that file only in project folder and can't find it because now the generated files (and .exe ...) are in a different folder. I didn't use this include very often, that is why i recommended you to split the example code in more files (a .h and a .cpp for that class) and in that case you don't need to include the .moc file

PS:sorry for double post

That's what we have "-I" compiler directive and DEPENDPATH and INCLUDEPATH qmake variables. It should all work regardless of which platform you use unless you have a broken project file. Otherwise Qt itself wouldn't build.

Wysota, thanks for the information, you are right it's only that "project" that doesn't work (i created a new one and it goes well)

Looks like the example project builds if we delete the "Release" and "tmp" folders form the project folder "appchooser", the compiler will generate the new ones in the folder "appchooser-build-desktop"

I still can't understand why in case of separate folders the old ones break the build, but when Qt Creator start to behave "strange" i think the deletion of old build files is what should be done first. Anyway i never had this problem with not finding a moc file because of the old build files.

It's not Creator that causes the behaviour - it is just a text editor, nothing more. It's the compiler (drived by (n)make) that decides what to process and how.
