[Development] Problems with QmlEngine and importPath

[Wehmer, Matthias]

Hi everybody,

After I've been given a clue about some test features in Qt5 I tried out the qqmlmoduleplugin test in tests/auto/qml in the Qt source directory.
It turned out that this test failed with the same symptoms we've observed in out project. I send you a shortend version of the output.
There seems to be a problem with the loading of dll's in windows.
Is anyone addressing this problem or should I report a bug? Is here anyone else using Qt with Windows XP or any other Windows version?

Thanks for your help.

Greetings
Matthias

Hi everybody,

we are currently suffering from the following problem: We fail to change the default directory for our custom qml plugins, that we have written in C++, and that we want to import (e.g. via import custom_plugin 1.0). That is the only directory our QML applications find the plugins is in the default import directory from the Qt5 directory. What is also strange is that the Qt Creator recognizes our plugin (i.e. the syntax highlighting works) in an arbitrary directory as long as the QML_IMPORT_PATH is set.

We are using Qt5 with the angle project and the Qt Creator.

That is what we've tried so far:

 1.  changing the QML_IMPORT_PATH: although this results in syntax highlighting in the Qt Creator, our application still doesn't find the plugins  2.  using QmlEngine::addImportPath( dest ) : the path is in the importPathList now, we've checked that, but the plugins can't be found anyway  3.  varying the qmldir files: doesn't work either

Is this a known problem or is there an error in our application?
Thank you in advance for your help.

Greetings
Matthias
