Qt OPC UA plugin

beecksche

Hi,
I've installed the Qt OPC UA module. I can run the Viewer example without any problems in Qt Creator, but if I delpoy the application it shows the error message: No Plugin available.

The example is deployed with windeployqt, I also copied the open62541_backend.dll from the plugins directory to the application directory manually .

My Steps:

git clone https://code.qt.io/qt/qtopcua.git
cd qtopcua
git checkout 5.13.1
qmake
nmake
nmake install

Why does the example run in Qt Creator and not after deploying?

@beecksche Have you run your app with the environment variable QT_DEBUG_PLUGINS set? That will print additional messages and could indicate what goes wrong.
