build: Stop using hermetic clang, libc++, etc
This brings our default build config more in line with what is
necessary for some platforms anyway: using the system-installed
toolchain and sysroot to build everything.
We will no longer fetch source or binaries for any specific build
tools, such as libc++, clang, gold, binutils, or valgrind.
The main part of this change is the changing of default gyp settings
in gyp_packager.py. For this, a bug in gyp_packager.py had to be
fixed, in which similar GYP_DEFINE key names (such as clang and
host_clang) would conflict, causing some defaults not to be installed
properly.
In order to enable clang=0 by default, some changes had to be made in
common.gypi:
- compiler macros added to fix a compatibility issue between
Chromium's base/mac/ folder and the actual OSX SDK
- replaced clang_warning_flags variables with standard cflags
settings, plus xcode_settings for OSX
- turned off warnings-as-errors for non-shaka code, rather than
allow-listing specific warning types, since we can't actually fix
those warnings on any platform
- disabled two specific warnings in shaka code, both of which are
caused by headers from our non-shaka dependencies
Also, one warning (missing "override" keyword) has been fixed in
vod_media_info_dump_muxer_listener.h.
Although these changes were done to make building simpler on a wider
array of platforms (arm64, for example), it seems to make the build a
bit faster, too. For me, at least, on my main Linux workstation:
- "gclient sync" now runs 20-30% faster
- "ninja -C out/Release" now runs 5-13% faster
The following environment variables are no longer required:
- DEPOT_TOOLS_WIN_TOOLCHAIN
- MACOSX_DEPLOYMENT_TARGET
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.
The following GYP_DEFINES are no longer required for anyone:
- clang=0
- host_clang=0
- clang_xcode=1
- use_allocator=none
- use_experimental_allocator_shim=0
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.
The following repos are no longer dependencies in gclient:
- binutils
- clang
- gold
- libc++
- libc++abi
- valgrind
The following gclient hooks have been removed:
- clang
- mac_toolchain
- sysroot

This is a placeholder. Shaka Packager depends on an old version of the
|
||||
Chromium build system, which unconditionally adds this folder to the library
|
||||
search path. We no longer fetch a copy of libc++-static, but chromium's
|
||||
common.gypi file can't be configured to exclude this from the linker path.
|
||||
Therefore we just add a placeholder here to silence linker warnings.
