Difference between QtCore4.lib and QtCore.lib

Hi,

I'm using CMake and VS2008. When I use cmake, it links against QtCore4.lib, QtNetwork4.lib etc for Debug versions of my project, and QtCore.lib, QtNetwork.lib for my Release version.

However, I can't link my projects using the QtCore.lib, QtNetwork.lib versions so the release version of my project wont link.

The following two lines -

Code:

---

QApplication a( argc, argv );
return a.exec();

---

give the following link errors -

Code:

---

1>Linking...
1>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __thiscall QApplication::~QApplication(void)" (__imp_??1QApplication@@UAE@XZ) referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: static int __cdecl QApplication::exec(void)" (__imp_?exec@QApplication@@SAHXZ) referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall QApplication::QApplication(int &,char * *,int)" (__imp_??0QApplication@@QAE@AAHPAPADH@Z) referenced in function _main

---

However if I rename QtCore.lib to QtCore4.lib for my relase project then I don't get the link errors.

I have built Qt using the following 2 commands -

C:\Qt\2009.02\qt>configure -no-qt3support -platform win32-msvc2008 -no-libtiff -no-phonon -no-phonon-backend -no-webkit -qt-sql-mysql -l libMySql -I C:\mysql\include -L C:\mysql\lib\opt -static -release

C:\Qt\2009.02\qt>nmake

What is wrong with the QtCore.lib, QtNetwork.lib versions?

Thanks,

Barry
