Build CoreELEC in a docker container

Following this guide GitHub - CoreELEC/coreelec-builder and perform a “sudo apt-get upgrade” before “make image” i’m getting this error:

CMake Error at cmake/StdFilesystem.cmake:22 (message): Toolchain doesn’t support std::filesystem with nor without -lstdc++fs

I think there is a problem with the Ccache version 4.10.2. I’m not an linux expert. Can anyone help / update the guide please?

cert

You have to be more clear when you get this error.

I tested here locally and I see no issue.
