BUILD-FROM-SOURCE.md

Building from source

• Even though it is well-explained, building from source requires skill, internet and time.

• You can try building on Android with Termux, but no support will be included for it.

• It is recommended to clone the PojavLauncher repository before starting Setting Up JRE

• git clone https://github.com/PojavLauncherTeam/PojavLauncher

Setting up JRE

• You can download it from CI Auto Builds if you don't want to/can't build.

• Source: PojavLauncherTeam/android-openjdk-build-multiarch

Android

• Clone the git repository of PojavLauncherTeam/android-openjdk-build-multiarch

git clone https://github.com/PojavLauncherTeam/android-openjdk-build-multiarch

• Change the directory to the cloned repository

cd android-openjdk-build-multiarch

• Download Android NDK r10e from here and place it in this directory with a file explorer. (Can't automatically download because of EULA)

::: warning Do not attempt to build using a newer or older NDK, it will lead to compilation errors. :::

iOS

• Get the latest Xcode (tested with Xcode 12).

./getlibs.sh

./buildlibs.sh

Clone JDK, run once

./clonejdk.sh

Configure JDK and build

Updating translations

• Updating translations is easier thanks to language list updater scripts

• Just run this command and it'll be automatically updated from Crowdin.

scripts\languagelist_updater.bat

chmod +x scripts/languagelist_updater.sh
bash scripts/languagelist_updater.sh

Build GLFW Stub

./gradlew :jre_lwjgl3glfw:build
