Both powerpc and powerpc64 builds are broken in the same way, in

successfully built world and kernel on June 6.

The error seen at this point is:

I've seen this both locally on my G5, and on the Power8 in the FreeBSD cluster.

- What does file say when you run it on libc.so.7?

/usr/obj/usr/src/lib/libc/libc.so.7: ELF 64-bit MSB shared object,
64-bit PowerPC or cisco 7500, version 1 (FreeBSD), dynamically linked,
not stripped
I think a libc linker could try for that command line lives in
/home/chmeee/world/zhabar/home/chmeee/freebsd/head/lib/libc/libc.so
or in
/home/chmeee/world/zhabar/home/chmeee/freebsd/head/tmp/lib/libc.so

But, the reason for your troubles seems to come from the
usr.bin/mkesdb/Makefile.  Why does it explicitely adds LDFLAGS to point
to objdir/.../libc, I have no idea.


Neither me.

Here with this mods it compiles:
