Building QFreeOpcUaPlugin and QOpen62541Plugin plugins Qt 5.10
-
The libraries from the backend you want to use. i.e.: open62541 or FreeOpcUa.
-
Now I got open62541_backend.dll, open62541_backendd.dll and libs in mingw53_32\plugins\opcua. But when I try to to compile example - project "accontrol" I got an error: E:\PROJECTS\accontrol\accontroltest.cpp:54: QtOpcUa/QOpcUaMonitoredValue: No such file or directory.
QOpcUaMonitoredValue class is missing in the source qtopcua-dev... Any ideas, please... -
Base on this commit, I'd say the example hasn't been update yet.

I am at the same staep as you. I have done the steps qmake, mingw32-make, mingw32-make install.
And then I have the same problem with the open62541 and freeopcua.My question is now, how do you get the open62541_backend.dll, open62541_backendd.dll and libs?
Many thanks in advance!

Hi,
AFAIK, build the corresponding project.

@SGaist You are right. The API is currently settling down. There will be a Tech Preview in Qt 5.11. The examples you currently find on the dev branch are outdated. New examples are in the pipeline. You can find the first here: https://codereview.qt-project.org/#/c/216519/

@N3ff3 please have a look at this article:
https://blog.basyskom.com/2018/want-to-give-qt-opcua-a-try/You should go with the open62541 backend. Open62541 is the more complete implementation and has a much more active community.
Note that open62541 will release their 0.3 version in the next few weeks. We plan to use this release in the Tech Preview in Qt 5.11.

@fmeerkoetter
thank you very much for the information and the link.Now I am testing the QtOpcUa. For this I use the Softing OPC UA .net Demo Server. The Problem is, that I can't connect to the server. I get this error message:
error/client No suitable UserTokenPolicy found for the possible endpointsAfter reading the docs of QtOpcUa, I can't find anything about the Policy.
Is there anything which I can use?
Best regards

I read that open62541 is the most stable and feature complete open source backend presently in Qt OPC UA so you won't experience any difficulties.
