Presearch Browser

Overview

This repository holds the build tools needed to build the Presearch desktop browser for macOS, Windows, and Linux. In particular, it fetches and syncs code from the projects defined in package.json and src/presearch/DEPS:

• Chromium
  • Fetches code via depot_tools.
  • sets the branch for Chromium (ex: 65.0.3325.181).
• presearch-core
  • Mounted at src/presearch.
  • Maintains patches for 3rd party Chromium code.
• adblock-rust
  • Implements Brave's ad-block engine.
  • Linked through brave/adblock-rust-ffi.

Build for Android

System Requirements

Before you begin, ensure your system satisfies the system requirements. The Android build can only be made on Linux machine. The process described in this instruction uses Ubuntu 20.

Setup build environment for Android

You will need Git, Python 3, the Node.js active LTS (v16+), and npm (v8+ but < 8.6). 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.

Clone and initialize the repo

Once you have the prerequisites installed, you can get the code and initialize the build environment.

git clone https://github.com/PresearchOfficial/presearch-browser-android.git
cd presearch-browser-android
npm install

# the Chromium source is downloaded, which has a large history
# this might take really long to finish

npm run init

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:

# Run this cli into the presearch-browser-android folder
./src/build/install-build-deps-android.sh

Making debug build for Android

presearch-browser-core based android builds should use npm run init -- --target_os=android --target_arch=arm (or whichever CPU type you want to build for)

Or set the target_os and target_arch for init and build using:

npm config set target_os android
npm config set target_arch arm # For 32 bits ARM
npm config set target_arch arm64 # For 64 bits ARM

Build Presearch

The default build type is component.

# start the component build compile
npm run build
