Qt OPC UA Open62541-Standalone Application
henrik2016 last edited by henrik2016
I created an OPC UA client in Qt 5.12.4 for Windows. I can start the standalone application on my computer. I've got all necessary libraries for OPC UA (Open62541). Now I want to start my application on a virtual maschine. So I copied my application and all the libraries. Qt is not installed on this maschine. When I start the my application, the QOpcUaProvider can't find any backends. Does Qt have to be installed for OPC UA Open 62541?
EDIT: I think a library is still missing.
EDIT: I re-created OPC UA and looked at the config.log file. Could that be the reason? And what do I have to do now?

EDIT: Now I installed Qt and the QtOPCUA Plugin on the virtual machine and finally it works! Any ideas for the reason?

no, you should find open62541_backend.dll in your app deployment directory under plugins\opcua

In addition to the Qt libraries, I have got Qt5OpcUa.dll and open62541_backend.dll, but it won't work.
