problems going from 4.3.x to 4.4.0

[Ovis]

Hi

I'm having some problems compiling an application that work perfectly fine under 4.3 but when I started using 4.4 all hell broke loose.

The application is originally developed in linux, but I'm are trying to move it over to windows. I'm using vs2008 so the release of 4.4 was greatly appreciated, if only I could get it to compile.

The error I'm getting is various forms of this

Line 44 refers to my code, but its a normal


class CAutoTuneModelEngine : public QObject {
Q_OBJECT;
//lots of other stuff,
vector<int> m_predMdlSingleList;
};



And I'm also getting reports like this, with no errors pointing to my code

Any help is GREATLY appreciated.....

You should try to break down the error - minimize your class until the error disappears to see what's triggering the error so we can see the real cause of the problem.

I am having the same compile errors as Ovis. Has anyone found a solution to this problem? Could this in any way be related to the compile issue between Qt and Visual Studio 2005 SP1? http://support.microsoft.com/kb/930198

EDIT:
I tried the hotfix and it did NOT resolve the compile errors I am getting.

It appears this is caused by having the Common Language Runtime project setting set to "Common Language Runtime Support (/clr)". Does Qt not support this compile option?

Hmm Ovis I see that you have "dotcomma - ;"(what is the name calling of this on English :P ) after the Q_OBJECT declaration, you must remove it. :)
