System Requirements

Before you begin, ensure your system satisfies the system requirements.

Install additional build dependencies

You will need Git, Python 3 and Node.js active LTS (v20+). You may need to make python3 the default if Python 2.7 is default for your OS. Also, if you don't have anything named python on your machine and only have python3, you will need something like python-is-python3.

If you are using Ubuntu, additionally install:

apt-get install build-essential python-setuptools python3-distutils

You are now ready to clone and initialize this repo. After npm run init is finished, there is one final step to finish installing build dependencies. This shell script only works on Debian and Ubuntu but check system requirements for other distros:

./src/build/install-build-deps.sh # for Linux

You might also want to try ./src/build/install-build-deps.sh --unsupported if above command gives an error about using a non supported Linux distribution.

Use ./src/build/install-build-deps.sh --android for Android builds.

Build Acceleration

Internal developers can find more information on remote build execution here

Build Configuration

Please refer to this document for information about setting up .env build configuration.

Troubleshooting

Check out the upstream Checking out and building Chromium on Linux docs before filing an issue.

Known issues

On debug build for Android lint may crash with error java.lang.OutOfMemoryError: Java heap space. Solution is to set environment variable export JAVA_OPTS="-Xmx10G -Xms1G".

Making debug build for Android

In order to make sure output format is apk, add --target_android_output_format=apk to build command:

npm run build -- Debug --target_os=android --target_arch=arm --target_android_output_format=apk

To change target SDK level, add --target_android_base, e.g.:

npm run build -- Debug --target_os=android --target_arch=arm --target_android_output_format=apk --target_android_base=mono

Installing a build on Android

Both for devices and if you have a started emulator:

./src/build/android/adb_install_apk.py ./src/out/android_Debug_x86/apks/Bravex86.apk

Or

adb install ./src/out/android_Debug_x86/apks/Bravex86.apk

If you have an aab file:

bundletool build-apks --connected-device --bundle=out/android_Debug_x86/apks/Bravex86.aab --output=out/android_Debug_x86/apks/Bravex86.apks
bundletool install-apks --apks=out/android_Debug_x86/apks/Bravex86.apks

Getting crash dumps for Android

adb logcat -d | third_party/android_platform/development/scripts/stack --output-directory out/android_Component_arm
