Android 6.0.1源码编译

本文主要记录Android 6.0.1源码编译的过程。

编译环境：Ubuntu 20.04.4、Nexus 5、Android 6.0.1、磁盘空间450G+、内存8G

初始化编译环境

sudo apt install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libncurses5 libxml2-utils xsltproc unzip vim

配置交换内存

sudo dd if=/dev/zero of=/swapfile bs=1M count=8k
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapoff /swapfile

sudo apt install vim
sudo vim /etc/fstab
/swapfile       none    swap    sw      0       3
reboot

配置adb

vim ~/.bashrc
export ADB_PATH=/home/tom/Desktop/Android/platform-tools
export PATH=$PATH:$ADB_PATH
source ~/.bashrc

配置repo

sudo apt install curl
curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o /home/tom/bin/repo
chmod +x ~/bin/repo

vim ~/.bashrc
export REPO_PATH=/home/tom/bin
export PATH=$PATH:$REPO_PATH
export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'
source ~/.bashrc

配置anaconda3

vim ~/.bashrc
export ANACONDA_PATH=/home/tom/anaconda3/bin
export PATH=$PATH:$ANACONDA_PATH
source ~/.bashrc

conda create -n python2.7 python=2.7
source activate
conda activate python2.7

配置git

sudo apt install git
git config --global user.name "tom"
git config --global user.email "tom@outlook.com"

初始化厂库

1 2	repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-6.0.1_r77 repo sync

漫长的等待，一下午and一晚上。

Ubuntu锁屏设置

Settings->Power-Never

配置openjdk

tar -xzf openjdk-7u75-b13-linux-x64-18_dec_2014.tar.gz
mv java-se-7u75-ri/ /home/tom/bin/
sudo vim /etc/profile
export JAVA_HOME=/home/tom/bin/java-se-7u75-ri
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile

sudo update-alternatives --install /usr/bin/java java /home/tom/bin/java-se-7u75-ri/bin/java 3
sudo update-alternatives --install /usr/bin/javac javac /home/tom/bin/java-se-7u75-ri/bin/javac 3
sudo update-alternatives --install /usr/bin/javadoc javadoc /home/tom/bin/java-se-7u75-ri/bin/javadoc 3

vim build/envsetup.sh
# 直接搜索set_java_home 修改JAVA_HOME为/home/tom/bin/java-se-7u75-ri

vim build/core/main.mk
:set number
注释掉171行的终止命令 #$(error stop)

下载、解压和安装驱动文件

地址：https://developers.google.com/android/drivers#hammerheadktu84p

tar -xzf broadcom-hammerhead-m4b30z-21cf8433.tgz 
tar -xzf lge-hammerhead-m4b30z-520d054d.tgz 
tar -xzf qcom-hammerhead-m4b30z-d6c0fe26.tgz 
mv ./*sh /home/tom/Desktop/SourceCode/Android6/

sh extract-broadcom-hammerhead.sh
sh extract-lge-hammerhead.sh
sh extract-qcom-hammerhead.sh

编译异常处理

修改源码art/build/Android.common_build.mk里的内容 ifneq ($(WITHOUT_HOST_CLANG),true) ==> ifeq ($(WITHOUT_HOST_CLANG),false)

设置高速缓存

echo export USE_CCACHE=1 >> ~/.bashrc
source ~/.bashrc

prebuilts/misc/linux-x86/ccache/ccache -M 50G

报错curl: option --no-proxy: used '--no-' for option that isn't a boolean

将/prebuilts/sdk/tools下面的jack第128行以及jack-admin第123行中的--no-proxy改为--noproxy

其它尝试解决报错3用到的命令，可能没什么用..

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx6g"
export LC_ALL=C
export JACK_JAR=./out/host/linux-x86/framework/jack.jar

编译

make clobber
source build/envsetup.sh
lunch
make -j10

历时1h10min，终于成功了
