Qt Compile Errors?

[magikalpnoi]

I've finished porting my qt3.3 to qt 4.2 code and now I am getting errors on Qt's code. I've already changed the QTDIR and PATH Environmental Variables to the new QT directory. I also changed the Additional Libraries and Dependencies in the Linker of my project to:
$(QTDIR)\lib
--and--
c:\Qt\4.2.0-rc1\lib\qtmaind.lib
c:\Qt\4.2.0-rc1\lib\QtGuid4.lib
c:\Qt\4.2.0-rc1\lib\QtCored4.lib
And lastly, I changed the Additional Include Directories to:
$(QTDIR)\include\
" " and all folders within \include\
C:\Qt\4.2.0-rc1\mkspecs\win32-msvc.net

Can anyone help me figure out why I am getting these QList errors?

Qt made files should not be throwing errors. Thank you so much in advance.

Qt made files should not be throwing errors.
Yes and they don't do it, unless you break them.

What do you have in c:\Documents and Settings\sm135c\Desktop\FitCheck\FitcheckDB.h file on line 26?

[magikalpnoi]

class QList;

Just a forward class declaration. That should be a huge problem right?

[magikalpnoi]

ACTUALLY WAIT! You are a GENIUS! I think that is the error. The QListVariant is a QVariant typedef not QList. Well played sir. Well played.

class QList;
It should be:

template < typename T > class QList;
