OPC client with Lazarus

[Truffaldino]

Hello, friends!
Has anyone managed to make an OPCUA component for Lazarus?
The wrapper from this topic is good, but the component is better.

Has anyone managed to get the wrapper to work correctly in Delphi? Everything works in Lazarus. In Delphi I can connect, read the values, but I can't add a variable on the server and I can't subscribe.
And even when reading values, if I make a second reading request after more than 30 seconds, I get the error: BadSessionIdInvalid.
I suspect there are differences in the configuration structures, but I haven't figured them out in two days.
I would be grateful for any suggestions.
I use the code: https://github.com/fluisgirardi/fpopen62541
Win32. Dll version: 1.2-RC2, 1.2.6

Hello, I'm also using the wrapper in Delphi, the test application connect to server but secure channel is closed.
connect state after connection : UA_SESSIONSTATE_ACTIVATED/UA_SECURECHANNELSTATE_CLOSED.

Can anyone tell me what I am doing wrong?
The same code is working fine in Lazarus

You must have also others DLLs there (beside libopen62541.dll):
- libgcc_s_sjlj-1.dll,
- libwinpthread-1.dll

Look at http://win-builds.org/1.5.0/packages/ (gcc and winpthreads package) or https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/8.1.0/threads-win32/sjlj/x86_64-8.1.0-release-win32-sjlj-rt_v6-rev0.7z
