Unable to create value change subscription

[apoorvcn47]

I am trying the example code giving here
https://github.com/FreeOpcUa/freeopcua/blob/master/src/examples/example_client.cpp

Server in this case is a fanuc robot. My code exits while I try to create value change subscription with following log

[2021-07-22 12:31:26.779] [UaClient] [info] ua_client | creating session ...

I know everything with server is fine because I can create value change subscription with python free opcua. Any idea?

Hello !

I'm a beginner in OPC UA and with that kind of programming.

I'm a bit lost with all that file but I can see you manage to build a project. I'm trying to set up the "example_server.cpp".

I'm using Visual Studio 2019 where can I begin?

Thanks a lot!

I haven't worked with windows in a long time, but all you have to do, is link .h,.so/.lib and .dll. You can do a simple google search to learn how to link these 3 kind of dependencies and its pretty straight forward
