-----------------------

Any ideas? I was planning on a toybox instead of busybox version, but that won't pass this problem either.

thanks

Start with the build commands in the script around line 12 and reproduce `make distclean defconfig` in `busybox-1.30.1`. Read the reported failures in `scripts/kconfig/mconf.c` and the surrounding Makefile targets. Done means the project’s documented build proceeds past `defconfig` without the reported errors.
