[The lldb problem is a: lldb_private::AppleObjCRuntime::GetFoundationVersion() reference via Cocoa.o in liblldb.a . See below.

But this likely will continue for some of my preliminary reports.] On 2017-Jul-23, at 5:00 AM, Dimitry Andric <dim@FreeBSD.org> wrote: > On 23 Jul 2017, at 11:17, Mark Millard <markmi@dsl-only.net> wrote: >>=20 >> [Linking lldb.full via 2.28 of /usr/local/powerpc64-freebsd/bin/ld >> also fails with "exit code 1" (using WIHTOUT_LLD so it gets that >> far).
