Android Kernel Build with Clang

When it comes to building the Android kernel, developers often use a variety of tools to optimize performance and ensure compatibility with different devices. One popular tool for building the Android kernel is Clang, a compiler that provides better code optimization and error checking compared to other compilers like GCC.

In this article, we will discuss how to build the Android kernel using Clang and provide a code example to demonstrate the process.

Why use Clang for Android kernel build?

Clang is known for its superior code optimization and error checking capabilities, which can result in better performance and stability of the kernel. It also provides support for modern C and C++ language features, making it a preferred choice for many developers.

Steps to build Android kernel with Clang

  1. Install Clang on your system:
sudo apt-get install clang
  1. Download the Android kernel source code:
git clone
  1. Configure the kernel build environment:
cd common
make ARCH=arm64 CC=clang defconfig
  1. Build the kernel using Clang:
make ARCH=arm64 CC=clang -j$(nproc)
  1. Once the build process is complete, you will have a compiled kernel image that you can flash onto your device.

Code Example

Here is a simple code snippet to demonstrate building the Android kernel with Clang:

sudo apt-get install clang
git clone 
cd common
make ARCH=arm64 CC=clang defconfig
make ARCH=arm64 CC=clang -j$(nproc)
