[Buildroot] busybox error

[Siva Prakash Reddy Nareddy]

Hi,
      I am getting the below errors while executing buildroot for
MPC8323E-RDB development board.

Please specify the Buildroot version you're using, and also your full
Buildroot .config so that we can reproduce the issue.

Thanks,

 You have done some very serious hacking, so don't be surprised if things don't
work.

 busybox runlevel can only be enabled when busybox FEATURE_UTMP is enabled.
However, Buildroot will explicitly disable that option when musl is used as libc
because musl doesn't provide utmpxname (and another one too I think).

 I don't know how you managed to break this, but it must be by manually copying
some files into the build directory. If you do something like that, you're on
your own. It's like pulling a screw out of the engine of your car and going to
your car dealer complaining that something doesn't work.

 Now, I could be mistaken, so if you can reproduce the issue after doing 'make
clean; make', please provide your buildroot .config and busybox .config (if it
was customized).


 Regards,
 Arnout

FWIW, Siva provided me off-list (or rather without Cc'ing the list) his
Buildroot .config file, which selects the glibc C library. But his
build log indeed indicates a toolchain built the musl C library.

Which hints very clearly that Siva didn't do a "make clean all" after
changing the toolchain configuration.

Siva: please read
https://buildroot.org/downloads/manual/manual.html#full-rebuild.

Thanks,

Thomas
