1 Setup Development Environment

1.1 Using Docker to Cross-Compile

Please refre to docker-cross-compiler-novnc

1.2 Build a cross-compiling environment

1.2.1 Install required packages

Install and run requirements ubuntu 20.04, install required packages using the following commands:

sudo apt-get -y update
sudo apt-get install -y sudo curl
sudo bash -c \
  "$(curl -fsSL https://raw.githubusercontent.com/friendlyarm/build-env-on-ubuntu-bionic/master/install.sh)"

The following cross-compilers will be installed:

Version Architecture Compiler path Purpose
4.9.3 armhf /opt/FriendlyARM/toolchain/4.9.3 Used for compiling 32-bit ARM applications
6.4 aarch64 /opt/FriendlyARM/toolchain/6.4-aarch64 Used for cross-compiling kernel 4.4
11.3 aarch64 /opt/FriendlyARM/toolchain/11.3-aarch64 Used for cross-compiling kernel 4.19 and above (including 5.10, 5.15) and U-Boot
1.2.2 Setting Cross Compiler

Based on the table in the previous section, select the appropriate version of the compiler and add the compiler's path to PATH. For example, if you want to use the 11.3 cross-compiler, edit ~/.bashrc using vi and add the following content to the end:

export PATH=/opt/FriendlyARM/toolchain/11.3-aarch64/bin:$PATH
export GCC_COLORS=auto

Run the ~/.bashrc script to make it effective in the current commandline. Note: there is a space after ".":

. ~/.bashrc

To verify if the installation was successful:

$ aarch64-linux-gcc -v
Using built-in specs.
