References

Get the code: Checkout, Build, & Run Chromium

Checking out and building Chromium on Linux

Building old revisions

System requirements

1. Disable IPv6 if behind GFW
2. Setup Docker
3. Docuble check curl, git, lsb_release, python3 and sudo

$ sudo apt install vim curl git
$ sudo apt install fonts-indic fonts-noto fonts-noto-cjk

Install depot_tools

$ cd ~/workspace
$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
$ vi ~/.bashrc
export PATH="$HOME/workspace/depot_tools:$PATH"
$ source ~/.bashrc
$ which fetch
~/workapce/depot_tools/fetch

Get the code

$ cd workspace
$ mkdir chromium
$ cd chromium
$ fetch --nohooks chromium

Install additional build dependencies

$ cd workspace
$ cd chromium/src
$ ./build/install-build-deps.sh

Run the hooks

$ cd workspace
$ cd chromium/src
$ gclient runhooks

Setup the build

$ cd workspace
$ cd chromium/src
$ gn args out/Default
is_debug = false
is_component_build = true
symbol_level = 0
blink_symbol_level = 0
v8_symbol_level = 0

$ gn gen out/Default

Build chromium

$ cd workspace
$ cd chromium/src
$ autoninja -C out/Default chrome

Run chromium

$ cd workspace
$ cd chromium/src
$ out/Default/chrome

Build old revisions

Sync a release tag

$ cd workspace
$ cd chromium/src

# Make sure you have all the release tag information in your checkout.
$ git fetch --tags

# Checkout whatever version you need (known versions can be seen with
# 'git show-ref --tags')
$ git checkout tags/74.0.3729.131
$ gclient sync --with_branch_heads --with_tags

Get compatible depot_tools

# Get date of current revision:
$ cd workspace
$ cd chrome/src
$ COMMIT_DATE=$(git log -n 1 --pretty=format:%ci)

# Check out depot_tools revision from the same time:
$ cd workspace
$ cd depot_tools
$ git checkout $(git rev-list -n 1 --before="$COMMIT_DATE" main)
$ export DEPOT_TOOLS_UPDATE=0

Clean your working directory

$ cd workspace
$ cd chromium/src
$ git clean -ffd

Sync dependencies

$ cd workspace
$ cd chromium/src
$ gclient sync -D --force --reset
$ gclient sync -D --force --reset --with_branch_heads

Warning: gclient sync may overwrite the URL of your origin remote if it encounters problems. You'll notice this when Git starts thinking everything is “untracked” or “deleted”. If this happens, fix and fetch the remote before continuing:

$ cd workspace
$ cd chromium/src
$ git remote get-url origin https://chromium.googlesource.com/chromium/deps/opus.git
$ git remote set-url origin https://chromium.googlesource.com/chromium/src.git
$ git fetch origin
