I am trying to compile 4diac forte on raspberry pi 4 from the develop branch. But when connecting sysfs, an error occurs (compilation error.png).
When running multiple times setup_posix.sh the error disappears, but the QX and IX function blocks are not created(run develop.png). Can you tell me how to fix the error?

Sorry for the late reply. When I saw your message I checked and thought it will be a quick fix. Unfortunately during one of the updates the process interface for sysfs was broken. This would need a bit of work for which I haven't found time yet.

Sir, please fix one of the module, sysfs or i2c as an example and I will try to fix the others. Thank you.

Unfortunately the situation is not so easy. Several of these IO systems still implement the old IO interface and should be migrated to the new modular IO system. Examples for these are modbus_ng or wago modular. The new IO subsystem would be much better suited and deliver better performance compared to how it is currently implemented. Therefore I'm not sure if it makes sense to just fix it.

I completely understand that there may still be many things that need to be improved. Thank you for your response.
