I give up googled the whole internet and beyond but no avail.

I rebuilded QT 4.2.1 static and that went cleanly. And when I try to recompile my project I keep geeting these errors. Please anyone I'm stuck deep.... Read something about moc'in the source but it seems to be done, so where's the error?

Are you sure you linked with Qt libs? As it looks like you didn't...

I didn't change nothing in my project and when I switch back to the non static build of QT and do a build clean it compiles fine.... When I check the properties they are all there linked...

I got two build of QT 4.2.1: 4.2.1 and 4.2.1-static

Part of the build log:

/OUT:"G:\Visual Studio 2005\Projects\GT-8 FX FloorBoard\Debug\GT-8 FX FloorBoard.exe" /LIBPATH:"C:\Qt\4.2.0-static\lib" /MANIFEST /MANIFESTFILE:"Debug\GT-8 FX FloorBoard.exe.intermediate.manifest" /DEBUG /PDB:"g:\Visual Studio 2005\Projects\GT-8 FX FloorBoard\Debug\GT-8 FX FloorBoard.pdb" /SUBSYSTEM:WINDOWS qtmaind.lib QtCored4.lib QtGuid4.lib QtXmld4.lib winmm.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib


Edit: Tried compiling it at the command line and it compiles fine with the static QT???
But when I import the .pro file and create a new project I still get the error's...
So it must be some setting in Visual Studio. Anyone experience with compiling static in Visual Studio?

I usually 1) update the environment variables (PATH, QTDIR), 2) change to the appropriate build in VS (Tools->Options->Qt), 3) restart VS and then 3) re-open the solution from the .pro file. This all just to avoid complications when switching from Qt build to another.

/LIBPATH:"C:\Qt\4.2.0-static\lib"

This part looks somewhat suspicious. You said you built 4.2.1 right?

So, are there really 4.2.1 libs in c:\qt\4.2.0-static\lib (instead of c:\qt\4.2.1-static\lib)? If not, then fix your paths, or put the libs in there.

And stuff compiles fine from the command line... I just cant get it to work from vs2005 (I must be really dumb :eek: )...

Yes this is looks like VS issue. What I did to fix it:

-created a new .pro file
-open new .vcproj file from .pro using QT Visual Studio integration

After these steps it works for me.

I am using Qt4.4.0 open source with VS 2005 in Window.
I installed Library path and linker data.
Can anybody help me this problem?

Thanks in advance.

Seems like you don't have debug version of Qt. So generate the project file in release mode:

qmake -tp vc -config release

Hi.. Thanks for your answer.
I tried it out in release version

qmake -tp vc -config release

then.. I found error

WARNING: Unable to generate output for C:/Qt/4.4.0/Makefile.Release [TEMPLATE vcapp]
WARNING: Unable to generate output for C:/Qt/4.4.0/Makefile.Debug [TEMPLATE vcapp]


What should I install for right version?
Should I delete and reinstall everything?
Please kindly reply me.

I meant to run that command in the project directory, not in Qt installation directory. That's the command to generate a Visual Studio project out of a qmake project file. That's how you created the Visual Studio project in the first place, right?

Thanks a lot.

I reinstalled MinGw with following components,
* MinGW base tools
* G++ compiler
* MinGW make

then I changed the path and type in VC command prompt
1. qmake -project
2. qmake
3. make
It work out now.
