2. Compile environment to build¶

2.1. Ready to compile¶

Compiling Android requires high machine configuration:

64-bit CPU
64GB physical memory + swap memory
250GB of free disk space

To build Android 14, you must use Ubuntu 20.04 or later.
To install required packages for Ubuntu 20.04 or later, run the following command:

sudo apt-get update
sudo apt-get install git-core gnupg flex bison build-essential \
zip curl zlib1g-dev libc6-dev-i386 x11proto-core-dev libx11-dev \
lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig

2.2. Compilation FAQ¶

Because everyone’s PC system version and environment configuration are different, the compilation after installing the software package is not necessarily successful, and it is inevitable that there will be some errors caused by the lack of some software packages, such as:

2.2.1. Q1¶

 OBJCOPY spl/u-boot-spl-nodtb.bin
  CAT     spl/u-boot-spl-dtb.bin
  COPY    spl/u-boot-spl.bin
  CFGCHK  u-boot.cfg
ERROR: No 'dtc', please: apt-get install device-tree-compiler

Don’t worry, we could install the lacking software package(dtc) according to the error message, just like you see:

apt-get install device-tree-compiler
