INCLUDEPATH how it works ?

[tonnot]

I'm using QT Creator ...

Then rerun qmake under Qt Creator.

Press Right Mouse button -> clean project -> Run qmake. Should working.

[tonnot]

Qmake does :

Starting: "d:/qt/2010.04/qt/bin/qmake.exe" d:/c++/plug1/plug1.pro -r -spec win32-g++
The process "d:/qt/2010.04/qt/bin/qmake.exe" exited normally.
And nothing more... (My application is not launched)
Then, if I do click on 'run' project all the building process is launched again with the same errors.

Tonnot, please do me a favour. Go through the basic Qt programming tutorial available in Qt documentation. Then get a decent book on C++ programming and read it. We're not here to teach you programming. And you obviously lack the basic knowledge regarding software development.

Yes, because of it I am here (newbie)
Sincerely, I dont know what is happen.
And my main question (the errors I get If I have the INCLUDEPATH ok but not have the .h file added at .pro file) is still without solution ...
Thanks

This is a Qt forum. We're helping with Qt issues. Not with I-don't-know-how-to-program issues. The "newbie" forum is for Qt newbies, not programming newbies. You have to learn by yourself how a compiler works, what are include files, etc.

Excuse me, but I think that I am not making so basic questions.
Of course, I'm learning c++ but I am not asking about how to declare a variable....

Ok, I'll treat you as a "programming grown-up" then.

Your problem is the implementation of the offending functions is provided by a precompiler that is ran on header files in search of the Q_OBJECT macro. Classes containing the macro are then scanned for keywords and definitions that later form the meta-object for the class which should then be included in the compilation and linked with the rest of object code. If qmake handles your build process then it pre-scans all files added to the variable containing the list of headers and if Q_OBJECT is spotted in any of them, the file is fed to moc and its result included in the compilation. So to solve your problem you need to make sure that moc preprocesses the files and its result is included in the rest of the compilation.

Uppps Sorry I didn`t see answer from wysota....

Qmake is kind of tool which can generate Makefiles. When you see into your build folder, there are files like Makafile.Debug, Makafile.Release(propably).
In that files there is a "kind of informction" what will be compiled and how(See ####### Compile). Maybe you should analyze this file, than some problems with compilation will be more clearly, maybe
