    Hello, today i have installed qt 4.7.0 for mingw and tried to launch example "chapter6-plugins" from "Tutorial: Writing QML extensions with C++" and i've got nothing.

    @Application output - Starting e:\progr\Qt\4.7.0\bin\qmlviewer.exe -I e:/progr/Qt/4.7.0/imports E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/app.qml
    file:///E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/app.qml:45:5: PieChart is not a type
    PieChart {
    ^
    @
    I have not modified an example. The same situation under Qt 4.7.1 for mingw. What am i doing wrong?

      Do you have PieChart.qml file included on your project?

        Have you compiled the plugin?

          Milot, PieChart is QDeclarativeExtensionPlugin. Yo can go to $QTDIR/examples/declarative/tutorials/extending/chapter6-plugins and look on this example.

          Kxyu, I have installed qt-win-opensource-4.7.0-mingw.exe where all examples are already compiled.

            Strange enough. I just tried compiling the example on Mac and it works!

            Also I was able to open the QML file with QMLViewer, can you try the same?

                Can you post the compiler error? The above error is QMLViewer error...

                  i do not compile this example, it was already compiled when i've installed qt.

                  qmlviewer gave me follow output "file:///E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/app.qml:45:5: PieChart is not a type

                      Strange enough!

                      Do you have contents (any lib, dll or something) under lib directory?

                      Here I have .dylib library for Mac OS.

                          Strange again.

                          Maybe someone who faced the issue can help us here, I will try that on the meantime on Windows.

                              That can work, and this is a bit an issue with not working examples, most of the developers are facing this issue which is also specified in "this article.":http://www.pluggd.in/nokia-qt-297/
