This also fixes a missing header in the SDK that rtags needs to work
properly. The underlying cause is that C++ headers got shuffled around a
lot in libc++ 3.8 (I believe) and became more standards-compliant, which
led to a lot of C-compatible passthrough header files being added to it
like math.h, which defines some C++-compatible versions of standard
functions like signbit, while #include_next'ing the system math.h. In
this case, including the SDK was stuffing another math.h in front of the
libc++ shim, which led to all sorts of mysterious failures.
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 is a slightly less ambitious version of the (now reverted) commit
377cef8d16, which had a bunch of issues
that I don't have time to resolve right now.
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
The SDK includes cups header files, but not the libraries. The
`nixpkgs.cups` definition doesn't build on darwin due to the SDK being
too old. This change symlinks the system cups libraries into the old
SDK.
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.
Darwin systems need to be able to find CoreFoundation headers as well as
libc headers. Somehow, gcc doesn't accept any "framework" parameters
that would normally be used to include CoreFoundation in this
situation.
HACK: Instead, this adds a derivation that combines the two. The result
works but probably not a good long term solution.
ALTERNATIVES: Maybe sending patches in to GCC to allow
"native-system-framework" configure flag to get this found.
It's a long build and generally painful to split into smaller commits,
so I apologize for lumping many changes into one commit but this is far
easier.
There are still several outdated parts of the darwin stdenv but these
changes should bring us closer to the goal.
Fixes #18461
Revert a revert of a merge that shouldn't have been in master but was intentionally in staging.
Next time I'll do this right after the revert instead of so far down the line...
This reverts commit 9adad8612b.
This currently only produces a static library, but is a start :) soon we
might be able to incorporate it into our stdenv, but we need to get the
build system to produce a proper .framework first.
We don't actually need the private headers and the private qos.h was
overwriting the public one, causing weird issues downstream (especially
with Swift's CoreFoundation)
I can't submit this in smaller units because the various components all
depend on one another during the stdenv bootstrap, so I think this is
the smallest sensible change I can make.
I also removed the symbol-hiding shenanigans in Libsystem. It might mess
up compatibility with 10.9 but I don't really want to support the added
complexity and I see little evidence of anyone else wanting to support
it. If someone cares, we might be able to revive compatibility, but for
now it'll stay like this.
The AVFoundation framework uses a relative path that presumes that
CoreGraphics is a child framework of ApplicationServices. It is not in
the 10.9 SDK.
This patch makes it one by tweaking the framework derivation generator
with special support to address this problem.
