@c4c @george1421 I can assure you that there should be nothing special that build.sh is pulling or doing. While we have different branches like master (latest official) and dev-branch (development) in the fogproject repo this is not the case in the fos repo. I always use fos master to build stuff. If I do really fance new things I create short temporary branches but merge those into master again as soon as things are ready to go.
One thing I just noticed in George’s desciption is using make -j4 to build. The official manual states that “Buildroot does not support top-level parallel build” (reference). Though I can’t really think of this causing the problem described.
If you work more on this you should also read this part of the manual: https://buildroot.org/downloads/manual/manual.html#full-rebuild - e.g.:
When a package is removed from the configuration, Buildroot does not do anything special. It does not remove the files installed by this package from the target root filesystem or from the toolchain sysroot. A full rebuild is needed to get rid of this package.
