This includes adding a new xcbuild-based libutil build to test the waters a bit there.
We'll need to get xcbuild into the stdenv bootstrap before we can make the main build,
but it's nice to see that it can work.
This requires some small changes in the stdenv, then working around the
weird choice LLVM made to hardcode @rpath in its install name, and then
lets us remove a ton of annoying workaround hacks in many of our Go
packages. With any luck this will mean less hackery going forward.
The main changes are in libSystem, which lost the coretls component in 10.13
and some hardening changes that quietly crash any program that uses %n in
a non-constant format string, so we've needed to patch a lot of programs that
use gnulib.
This sort of thing is going to get revamped to be less hackish soon but
for now I want it to work. In this particular case, libc++ 4 (and maybe
earlier) gets very upset if we're imprecise about our const markers, and
I guess libauto was careless. This fixes it (PtrPtrMap) to be correct.
This wasn't being used and it was causing an error when evaluating:
error: attribute ‘CoreOSMakefiles’ missing, at /Users/mbauer/Projects/nixpkgs2/pkgs/os-specific/darwin/apple-source-releases/default.nix:140:71
pkill isn't building because of some missing headers:
- xpc/xpc.h
- os/base_private.h
- _simple.h
They are all available somewhere but not set up correctly in the Darwin
stdenv.
TODO: add pkill back in!
This actually has no effect but it bugged me to keep seeing an old version
in the package names :) and since we're making a bunch of stdenv changes
at once, I might as well.
This reinstates the libSystem selective symbol export machinery we used
to have, but locks it to the symbols that were present in 10.11 and skips
the actual compiled code we put into that library in favor of the system
initialization code. That should make it more stable and less likely to
do weird stuff than the last time we did this.
