Building

Build steps are mostly the same as the original Chromium's one except for compatibility patches.

prerequisites

• macOS 13.3 SDK
  • need a patch for SDK:
    • /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/GameController.framework/Headers/GCDevice.h

  • to build for 10.7, also need patches for SDK:
    • /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Foundation.framework/Headers
      • NSArray.h
      • NSDictionary.h
• Xcode 13+
  • to build for 10.7, need patched clang
• powerful CPUs
  • about 40mins to distributed build from scratch with Ryzen 9 5950X + 2 x Ryzen 9 3950X
  • about 3-4hrs+ to build from scratch with Core i9-9980HK

Note: Setting min build target to 10.9 instead of 10.7 may be necessary if you run into issues with visibility of certain math.h functions like sincospif. (This can also be worked around by modifying SDK to force inline and change visibility).

steps

first setup & build:

# setup working dir
mkdir -pv chromium-project && cd chromium-project

# prepare patched clang
mkdir -pv clang-master && pushd clang-master
curl -LOJ https://github.com/blueboxd/llvm-project/releases/download/main/main.tar.xz
tar xvf main.tar.xz
popd

# setup depot_tools
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git && export PATH=`pwd`/depot_tools:"$PATH"

# setup project dir
mkdir -pv chromium-legacy && cd chromium-legacy
# place this repo as src
curl -OJL https://gist.githubusercontent.com/blueboxd/c1f355fb6fe829e98ff5453880683993/raw/9d97a2c622c206fd7bc03ec891ad89dd58be4004/.gclient


# checkout sources & dependencies
gclient sync -v --no-history

# setup patched skia
pushd src/third_party/skia
git remote add github https://github.com/blueboxd/skia.git
git fetch github && git checkout for-lion && git checkout for-lion -- .
popd

# setup patched angle
pushd src/third_party/angle/
git remote add github https://github.com/blueboxd/angle.git

popd

# setup out dir
mkdir -pv out/release
pushd out/release
# setup args.gn with basic parameters
curl -OJL https://gist.githubusercontent.com/blueboxd/c1f355fb6fe829e98ff5453880683993/raw/9d97a2c622c206fd7bc03ec891ad89dd58be4004/args.gn
popd

# use patched clang
pushd ../clang-master
echo "clang_base_path=\"`pwd`\"" >> ../chromium-legacy/out/release/args.gn
popd

# generate build files
cd src
gn gen ../out/release

# build
time ninja -C ../out/release chrome

# now your build is ready
open -R ../out/release/Chromium.app

to update src:

cd chromium-project
export PATH=`pwd`/depot_tools:"$PATH"

# pull origin/master.lion
cd chromium-legacy/src
