1 Setup Development Environment
1.1 Method 1: Using docker to cross-compile
Please refre to docker-cross-compiler-novnc
1.2 Method 2: Setup build environment on the host machine
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 \ "$(curl -fsSL https://raw.githubusercontent.com/friendlyarm/build-env-on-ubuntu-bionic/master/install.sh)"
The following cross-compilers will be installed:
| Version | Architecture | Compiler path | Purpose |
|---|---|---|---|
| 4.9.3 | armhf | /opt/FriendlyARM/toolchain/4.9.3 | Can be used to build 32-bit ARM applications |
| 6.4 | aarch64 | /opt/FriendlyARM/toolchain/6.4-aarch64 | Can be used to build kernel 4.4 |
| 11.3 | aarch64 | /opt/FriendlyARM/toolchain/11.3-aarch64 | Can be used to build kernel 4.19 or higher and U-Boot |
1.2.2 Setting the compiler path
Based on the table in the previous section, select the appropriate version of the compiler and add the compiler's path to PATH. For example, if you want to use the 11.3 cross-compiler, edit ~/.bashrc using vi and add the following content to the end:
export PATH=/opt/FriendlyARM/toolchain/11.3-aarch64/bin:$PATH export GCC_COLORS=auto
Run the ~/.bashrc script to make it effective in the current commandline. Note: there is a space after ".":
. ~/.bashrcTo verify if the installation was successful：
$ aarch64-linux-gcc -v Using built-in specs.
