I’m trying to reproduce the Qt example “webbrowser” (from qt-everywhere-opensource-src-4.8.3/examples/activeqt/webbrwowser) with VS2010 ((I work on windows7 x64).

So, I copied all files (.h and .cpp) from webbrowser folder to my project.
Also, in Project properties–>Linker–>input–>additional directives I added the following libraries:

phonon4.lib
QAxServer.lib
Qt3Support4.lib
QtCLucene4.lib
QtCore4.lib
QtDeclarative4.lib
QtDesigner4.lib
QtDesignerComponents4.lib
QtGui4.lib
QtHelp4.lib
Qtmain.lib
QtMultimedia4.lib
QtNetwork4.lib
QtOpenGL4.lib
QtScript4.lib
QtScriptTools4.lib
QtSql4.lib
QtSvg4.lib
QtTest4.lib
QtUiTools.lib
QtWebKit4.lib
QtXml4.lib
QtXmlPatterns4.lib

Now, when I press Debug button, I get these errors:

I solved my problem. I linked libraries for release mode, but I compiled in debug mode. So the right libraries to link are:

     phonond4.lib
    QAxServerd.lib
    Qt3Supportd4.lib
    QtCLucened4.lib
    QtCored4.lib
    QAxContainerd.lib

and so on.
Hope it is of help to someone!
