I just downloaded QT for the first time. I installed the new 5.0RC2 SDK. I created a new project and set the compiler to mingw C:\MinGW\bin\gcc.exe http://doc.qt.digia.com/qtcreator-2.4/creator-tool-chains.html

But if I try to compile it I get tons of error message that look like this

C:\Qt\Qt5.0.0-rc2\Tools\QtCreator\bin\GL\main.cpp:8: error: undefined reference to `_imp___ZN7QWidget4showEv'

I also set the compiler in kit to mingw and the device type to desktop.

Any ideas what went wrong?

Edit:

Okay I probably know the problem. http://qt-project.org/downloads QT5 is only available for vs2010.( It’s a little bit hidden). I just try QT 4.8 for mingw then.

    try adding this line in the .pro

     CONFIG(release, debug|release): LIBS += "C:\\Qt\\4.8.3\\lib\\QWidget4.a"

    replace the path to the lib folder in yours. and QWidget4.a from similar one that the error says and available in the lib folder.

    this is just a suggestion. have a try.
