1 使用清华的源

1.1 备份sources.list

sudo cp -f /etc/apt/sources.list /etc/apt/sources.list.bak

1.2 用下面的内容替换/etc/apt/sources.list里面的内容

1.3 更新源

sudo apt-get update

2 安装编译环境

  sudo apt-get install curl
  sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib
  sudo apt-get install -y git flex bison gperf build-essential libncurses5-dev:i386
  sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386
  sudo apt-get install git-core gnupg flex bison gperf build-essential
  sudo apt-get install zip curl zlib1g-dev gcc-multilib g++-multilib
  sudo apt-get install libc6-dev-i386
  sudo apt-get install lib32ncurses5-dev x11proto-core-dev libx11-dev
  sudo apt-get install libgl1-mesa-dev libxml2-utils xsltproc unzip m4
  sudo apt-get install lib32z-dev ccache
  sudo apt-get install libssl-dev
  sudo apt-get install dpkg-dev libsdl1.2-dev libesd0-dev -y
  sudo apt install libncurses5 gawk -y
  sudo apt-get install openssh-server

sudo apt-get install repo ssh make gcc liblz4-tool expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support qemu-user-static live-build bison flex fakeroot cmake device-tree-compiler python-pip zstd rsync bc time

若sh 不为bash，请将symlink /bin/sh→dash 更改为/bin/sh→bash。

1. 使用如下命令：

sudo rm /bin/sh

1. 使用如下命令：

sudo ln -s /bin/bash /bin/sh

3 常用编译命令

cd 到项目的根目录 RK3568_ANDROID13R01RKR3

3.1 设置项目的编译命令，环境变量

source build-quec.sh

==这一步是其它编译命令的基础==

3.1 编译所有模块

build-all-image

3.2 编译android

./build -A

3.2 编译kernel

makekernel

3.3 编译uboot

makeboot

3.4 编译android

./build.sh -A

3.5其它编译命令

可以通过

./build.sh -?

来查看：

/RK3568_ANDROID13R01RKR3$ ./build.sh -?
./build.sh: illegal option -- ?
USAGE: [-U] [-CK] [-A] [-p] [-o] [-u] [-v VERSION_NAME]  
No ARGS means use default build option                  
WHERE: -U = build uboot                                 
       -C = build kernel with Clang                     
       -K = build kernel                                
       -A = build android                               
       -p = will build packaging in IMAGE      
       -o = build OTA package                           
       -u = build update.img                            
       -v = build android with 'user' or 'userdebug'    
       -d = huild kernel dts name    
       -V = build version    
       -J = build jobs

编译生成的各种镜像的目录是

\RK3568_ANDROID13R01RKR3\rockdev\Image-rk3568_t
