This configuration applies to Official Release builds only.
Chromium currently provides PGO profiles for Windows x86/x64, MacOS x64/ARM64
and Linux x64. Official builds for these platforms must run automate-git.py with
the `--with-pgo-profiles` command-line flag. Official builds for other platforms
must disable PGO builds by adding `chrome_pgo_phase=0` to GN_DEFINES.
To generate Windows ARM64 builds set the CEF_ENABLE_ARM64=1 environment
variable and pass the "--arm64-build --build-target=cefsimple" command-line
arguments to automate-git.py. We can't build cefclient.exe for ARM64 due to
missing OpenGL library support so build cefsimple.exe instead.
Requires Xcode 12.2 and the MacOS 11.0 SDK. To generate ARM64 builds set
the CEF_ENABLE_ARM64=1 environment variable and replace all usage of
--x64-build with --arm64-build in script command-line arguments.
- CefURLRequest::Create is no longer supported in the renderer process
(see https://crbug.com/891872). Use CefFrame::CreateURLRequest instead.
- Mac platform definitions have been changed from `MACOSX` to `MAC`
(see https://crbug.com/1105907) and related CMake macro names have
been updated. The old `OS_MACOSX` define is still set in code and CMake
for backwards compatibility.
- Linux ARM build is currently broken (see https://crbug.com/1123214).
Split `gclient sync` into separate `gclient sync --nohooks` and
`gclient runhooks` steps so that we can optionally apply patches
from `runhooks.patch` in-between. This is necessary because the
src/tools/clang/scripts/update.py script is run via a hook and has
dependencies on the VS toolchain scripts which must be patched to
properly consider the GYP_MSVS_VERSION environment variable.
- Add new command-line flags:
--chromium-url: Allows overriding the synced Chromium URL.
--no-cef-update: Allows bypassing the step to sync CEF.
--no-chromium-update: Allows bypassing the step to sync Chromium.
--no-depot-tools-update: Allows bypassing the step to update depot_tools.
--distrib-subdir: Allows specifying the subdirectory name of
chromium/src/cef/binary_distrib.
- Add support in make_distrib.py for the --distrib-subdir flag.
- Change CMake requirement from 2.8.12.2 to 2.8.12.1.
- Remove support for SVN checkouts (issue #1577).
- Use new Bitbucket cef.git repo for Git checkouts (issue #1577).
- Windows: Set DEPOT_TOOLS_WIN_TOOLCHAIN=0 to avoid errors while
running Chromium hooks (issue #1533).
- Fix create/restore of out_<branch> directories.
