A Cross-Compilation Environment Based on the Ubuntu 22.04 ARM64-bit System

Because the author needs to compile related feature packages for the rk3588, there will be some software packages related to the rk3588 in the root filesystem; however, this does not affect any other functionality.

Install the cross-compilation toolchain

sudo apt update
sudo apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu qemu-user-static binfmt-support

Build a cross-compilation environment rootfs

git clone https://github.com/kaylorchen/rk3588_dev_rootfs.git
cd rk3588_dev_rootfs
bash ./build-rootfs.sh

Compile your code using the cross-compilation environment

Following the steps above, a file named "toolchain-aarch64.cmake" will be generated in the current directory. You will need to use it in your CMake project. For example:

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=/opt/data/orangepi/rk3588_dev_rootfs/toolchain-aarch64.cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON ..
make 

/opt/data/orangepi/rk3588_dev_rootfs/toolchain-aarch64.cmake is an absolute path

Update your rootfs

When we compile code, sometimes we find that some dependency packages are missing. We need to update our rootfs.

1. edit config.sh, add a new package named "aaa":

#!/bin/bash
apt update
apt install -y --no-install-recommends vim libopencv-dev g++ gcc \
fakeroot devscripts libspdlog-dev libsystemd-dev libcap-dev liblz4-dev \
libgcrypt-dev libzstd-dev debhelper rknpu2-dev librockchip-mpp-dev librga-dev \
libstb-dev libturbojpeg0-dev libjpeg-turbo8-dev kaylordut-dev aaa

kaylordut-dev is my private library, you can find it via https://github.com/kaylorchen/kaylordut

2. update rootfs

./update.sh
