Post by nano on Error building Extension SDK Linux code ^{CODESYS Forge talk (Post)}
Hey schnepper, when i look into your c-file, i would say that only the main-function is declared with cext-addendum in your codesys-library-project. all yöur funtions in library has to be the cext-addendum when the external implementation is activ. if i remeber right, methods and other subelements dont need that, but every base-elements

Is there any update on this? Running codesys 3.5.19.70 proj = projects.open(project_path, primary=True, update_flags=flags) This gives an error only when using --noUI exception System.NullReferenceException: Traceback (most recent call last): File "C:\Project\ci\build.py", line 14, in <module> SystemError: Object reference not set to an instance of an object. Exit code: 1</module>

Some developers export ST code manually and edit it in VSCode, then copy it back. However, a more practical approach might be using automation scripts (PowerShell, Python) to extract and inject code into the CODESYS project. You could also check if CODESYS Automation Server or CODESYS API allows better ST access for external tools. https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html Network drive issues are particularly painful. As a mitigation, you could try using local project storage with periodic cloud sync instead of directly saving to a network drive. Using Rsync or Syncthing for automatic but safe synchronization might reduce risks of file corruption.

An other approach is to split the application into a hard real-time part running in CODESYS and the business logic running in Python asyncio. The business logic part is usually bigger and changes more often. As Python code is pure text, vscode and git are your friends. A performance example on YouTube (CODESYS SoftMotion + Python): https://www.youtube.com/watch?v=BT-L0H_4Aic Docs and code on GitHub: https://github.com/arwie/controlOS_demo/blob/main/docs/codesys_python_link.md Real-time variable exchange between a CODESYS application and a Python application running in parallel, using POSIX shared memory.

Solved. Enable this feature by editing C:\ProgramData\CODESYS\Devices\89\0000 0005\4.4.0.0\device.xml (config params 9105 and 9106).

That solved it, thank you for the swift resolution! :) It would be fantastic ,if bandwidth permitting, the placeholder 'C:/temp' could be updated to 'C:\Program Files\CODESYS 3.5.19.60\GatewayPLC'. Anyway, thanks again for your assistance!

Yes, it's very tedious, especially since Codesys 4 is a custom web development... At Rex Automatisierungstechnik GmbH, we've invested a lot of time in the Python interface to enable something like CI/CD, but also to export the code and re-import it after making clean modifications. Also, the fact that a class/function block is just a single file containing all the methods, props, etc. Yes, and right now I’m building my own VS Code extension with a clean LSP (Language Server Protocol) for ST, as well as an st-validator, st-formatter, st-linter, codesysPackage.json, and codesys_modules folder... Best regards, Steven Schalm / Sharok6130
