[Qt-interest] Problems with plugins on macos X

[denebet]

Hello,

I am trying to make qt's own plugins working on mac os.

In my bundle, I have created a plugins folder in the /Contents/MacOs folder.
In my app, I do addLibrayPath(applicationDirPath()+"/plugins")) .
It is ok before relocating my framework (surely because it is using plugins
whose path is hardcoded in qt) but once it is relocated it fails when the
jpeg plugin should be loaded.

QObject::moveToThread: Current thread (0x598d10) is not the object's thread
(0x5fb320).
Cannot move to target thread (0x50ad50)

On Mac OS X, you might be loading two sets of Qt binaries into the same
process. Check that all plugins are compiled against the right Qt binaries.
Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are
being loaded.
QObject::moveToThread: Current thread (0x59ae60) is not the object's thread
(0x1ee28b60).

What I am doing wrong.

Thanks for any help,

Alain
