    Hello, I just installed Qt and wanted to try some examples. I couldn't build many of them. I use Windows 7 and I built for Desktop. I got these errors from Affine Transformations, Arthur Plugin:
    @:-1: error: cannot find -ldemo_shared
    :-1: error: collect2: ld returned 1 exit status
    @

    Plug & Paint gave this:
    @:-1: error: cannot find -lpnp_basictoolsd
    :-1: error: collect2: ld returned 1 exit status@

    Boxes:
    @C:\QtSDK\Demos\4.7\boxes-build-desktop-Qt_4_8_0_for_Desktop_-MinGW__Qt_SDK__Debug..\boxes\qtbox.cpp:-1: In member function 'virtual void QtBox::paint(QPainter*, const QStyleOptionGraphicsItem*, QWidget*)':

    -_MinGW__Qt_SDK__Debug..\boxes\qtbox.cpp:327: error: 'gluPerspective' was not declared in this scope@
