Ubuntu 18.04.1 编译 Android6.0 源码

Open JDK 安装

1. 每个 Android 版本需要对应的 OpenJDK 版本，Android 6.0 需要对应的是 OpenJDK 1.7.
2. Ubuntu 下载 OpenJDK 1.7

$ sudo add-apt-repository ppa:openjdk-r/ppa
$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk
# 或者[参考](https://blog.csdn.net/wanghuasn911/article/details/80155648)

编译环境依赖包

$ 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 dpkg-dev libsdl1.2-dev 
$ sudo apt-get install libesd0-dev # 这个没装上，找不到包
$ 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

修改源码中编译的条件 ifneq to ifeq, true to false

// line 75
ifneq ($(WITHOUT_HOST_CLANG),true)
// to 
ifeq ($(WITHOUT_HOST_CLANG),false)

开始编译三指令

// cd 到源码跟目录
$ source build/envsetup.sh
$ lunch 
  > aosp_arm64-eng # 选择需要编译的版本
$ make -j8

启动模拟器

# 需要配置源码的 emulator 目录到 PATH
export PATH=$PATH:~/Android-5.0.2_r1/out/host/linux-x86/bin 
export ANDROID_PRODUCT_OUT=~/Android-5.0.2_r1/out/target/product/generic 
# 变量只对当前登录有效

$ emulator
