About

AOSP created build.sh to compile their kernels but deprecated it in Android 13 and used kleaf instead

This project aims to maintain build.sh and ensure compatibility with all kernel trees

Setup

1. Clone this repo to build directory in your kernel source
2. Run scripts from the parent directory of build (see Manual)

bulid.config file

A build configuration file must be specified in the BUILD_CONFIG variable when invoking any script. If not, you will be prompted to select a config file (if found)

See variables.md for a full list of build options

This file will be sourced by build.sh and functions like a shell script

Note: All variables in this file are exported and available to build.sh sub-processes (e.g. Make)

Manual

build.sh

Usage

build/build.sh <make options>*

To define custom out and dist directories:

OUT_DIR=<out dir> DIST_DIR=<dist dir>build/build.sh <make options>*

To use a custom build config:

BUILD_CONFIG=<path to the build.config><make options>*

Examples:

To define custom out and dist directories:

OUT_DIR=output DIST_DIR=dist build/build.sh -j24 V=1

To use a custom build config:

BUILD_CONFIG=common/build.config.gki.aarch64 build/build.sh -j24 V=1

To use a CC wrapper:

build/build.sh CC="ccache clang"
