Compile Sources / compile SDCC

[seeers]

I would like to experiment with the current firmware and perhaps even develop a small feature.
Unfortunately, the attempts to compile the current firmware are already failing.
I made the first attempt with these instructions: https://github.com/atc1441/ZBS_Flasher/tree/main/custom-firmware#compiling-on-windows

Under Linux I had problems compiling the SDCC version.
Is there perhaps an overview of which packages I need to install to successfully complete the SDCC build script?

Or is there possibly a docker container that contains all dependencies?

Thank you very much
