Ubuntu20.4编译AOSP源码实践

本文记录使用Ubuntu20.4编译AOSP的过程以及一些错误解决，使用的编译的分支为 android-8.1.0_r38

参考清华大学开源软件站构建代码仓库，本文采用repo同步的方式进行构建，构建的操作系统是Ubuntu20.4

一.Ubuntu虚拟机配置

主要关注内存和磁盘大小，本文中我分配了8G内存和200G的磁盘空间

二.依赖库安装

需要安装java环境、官方给定的环境依赖，ubuntu20.4自带python环境，如果没有需自行安装，用到的命令如下

# 环境安装
echo "更新apt-get"
sudo apt-get update
echo "安装jdk8"
yes | sudo apt-get install openjdk-8-jdk
echo "安装python2"
yes | sudo apt-get install python
echo "安装curl"
yes | sudo apt-get install curl
echo "安装git"
yes | sudo apt-get install git
echo "安装依赖"
yes |  sudo apt-get 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 ccache libgl1-mesa-dev libxml2-utils xsltproc unzip
echo "设置git账户"
git config --global user.email "Cubeeeeee@qq.com"
git config --global user.name "Cubeeeeee"

三.AOSP源代码同步

使用清华源同步，代码如下

# 源代码同步
echo "需要将脚本放到工作目录下执行"
mkdir -p ~/bin
PATH=~/bin:$PATHsudo curl -k https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo
sudo chmod a+x ~/bin/repo
cd ~/bin/aosp
export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'
# 如需其他分支 修改此处
yes | repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-8.1.0_r38
echo "开始同步AOSP源码"
repo sync

同步成功后如下图

如果同步失败请移步下文错误解决汇总

四.源码编译

涉及到的命令如下，如果出错可以参考下文错误解决

cd ~/bin/aosp
# 如果内存够大可以考虑设置缓存
# prebuilts/misc/linux-x86/ccache/ccache -M 50G 
# 根据自己内存大小调整  默认用6g
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx6g"
make clobber
source build/envsetup.sh
# 版本根据需要修改
# lunch 24
lunch
# 线程数根据处理器数量修改
make -j4

五.错误解决

1.Curl下载Repo报SSL Error

添加-k参数，忽略https证书错误 即修改为

sudo curl -k https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo

2.同步源码出错，git报CA证书错误

server certificate verification failed. CAfile: none CRLfile: none

禁用git的ssl校验即可

git config --global http.sslverify false
git config --global https.sslverify false

3.同步源码出错，无法连接到 https://android.googlesource.com/

未正确配置环境变量，检查~/.bashrc，正确配置如下图

或者在同一终端执行

export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'

4.同步源码出错,python相关错误

修改python优先级，默认使用python3

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150

5.编译报错Jack server(35). Try ‘jack-diagnose’

详细报错内容如下:

[ 10% 538/4980] Ensuring Jack server is installed and started
FAILED: setup-jack-server 
/bin/bash -c "(prebuilts/sdk/tools/jack-admin install-server prebuilts/sdk/tools/jack-launcher.jar prebuilts/sdk/tools/jack-server-4.11.ALPHA.jar  2>&1 || (exit 0) ) && (JACK_SERVER_VM_ARGUMENTS=\"-Dfile.encoding=UTF-8 -XX:+TieredCompilation\" prebuilts/sdk/tools/jack-admin start-server 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update server prebuilts/sdk/tools/jack-server-4.11.ALPHA.jar 4.11.ALPHA 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-4.32.CANDIDATE.jar 4.32.CANDIDATE || exit 47 )"

ninja: build stopped: subcommand failed.
22:32:18 ninja failed with: exit status 1#### failed to build some targets (01:11 (mm:ss)) ####Build android failed!

解决方案为修改/etc/java-8-openjdk/security/java.security文件，取消TLSv1, TLSv1.1 禁用，修改后内容如下

6.编译报错，Python相关错误

错误内容

system/core/libsysutils/EventLogTags.logtags system/core/logcat/event.logtags system/core/logd/event.logtags system/core/storaged/EventLogTags.log
tags”
File “build/tools/merge-event-log-tags.py”, line 51
except getopt.GetoptError, err:
^
SyntaxError: invalid syntax
[ 0% 6/89331] Ensuring Jack server is installed and started
Jack server already installed in “/root/.jack-server”
Server is already running
ninja: build stopped: subcommand failed.

错误原因是编译时需要使用python2.7(源码同步时使用python3.8)，只需修改python优先级，优先使用python2.7即可

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 150
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 100

7.编译报错Jack server(52). Try ‘jack-diagnose’

错误示例

[ 76% 69866/91547] Building with Jack:...k_intermediates/with-local/classes.dex
FAILED: out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/with-local/classes.dex 
/bin/bash out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/with-local/classes.dex.rsp
Communication error with Jack server (52). Try 'jack-diagnose'
[ 76% 69869/91547] //art/compiler:liba...izing/code_generator_x86_64.cc [linux]
ninja: build stopped: subcommand failed.
06:32:11 ninja failed with: exit status 105:16:52.810: INFO: com.android.jack.server.JackHttpServer: Jack 1.3-rc7 'Douarn' (445000 d7be3910514558d6715ce455ce0861ae2f56925a by N/A) available in ./jack/jack-1635487485073-0.jar
05:16:52.811: INFO: com.android.jack.server.JackHttpServer: Starting service connection server on /127.0.0.1:18076

解决方案是设置 JACK_JAR环境变量，在同一终端执行export命令或者写入~/.bashrc即可解决，

如果仍未解决可以尝试同时修改

$HOME/.jack-settings和$HOME/.jack-server/config.properties

中的端口号（比如都改为8386/8387）

8.编译报错 Aborted (core dumped)

错误内容如下

flex-2.5.39: loadlocale.c:130: _nl_intern_locale_data: Assertioncnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed. Aborted (core dumped)

执行

export LC_ALL=C

去除本地化设置

9.编译报错缺少libncurses.so.5

缺少依赖

sudo apt-get install libncurses*

六.脚本整合

为了便于使用，我将上述过程整理成了几个自动化脚本文件，在Ubuntu20.4下可以自动进行环境配置、源码同步、源码编译

envinstall.sh 环境安装

# 环境安装
echo "更新apt-get"
sudo apt-get update
echo "安装jdk8"
yes | sudo apt-get install openjdk-8-jdk
echo "安装curl"
yes | sudo apt-get install curl
echo "安装git"
yes | sudo apt-get install curl
echo "安装依赖"
yes |  sudo apt-get 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 ccache libgl1-mesa-dev libxml2-utils xsltproc unzip
echo "设置git账户"
git config --global user.email "Cubeeeeee@qq.com"
git config --global user.name "Cubeeeeee"
# 修改java配置文件 否则jack会报 35错误
sudo cp /etc/java-8-openjdk/security/java.security /etc/java-8-openjdk/security/java.security.bak
sudo rm /etc/java-8-openjdk/security/java.security
sudo cp java.security /etc/java-8-openjdk/security/java.security

repo.sh 拉取代码

# 源代码同步
echo "需要将脚本放到工作目录下执行"
mkdir ~/bin
temp=$(pwd) | PATH=$temp:$PATH
# 同步源码时使用python3
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150
sudo curl -k https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo
sudo chmod a+x ~/bin/repo
export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'
# 如需其他分支 修改此处
yes | repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-8.1.0_r38
echo "开始同步AOSP源码"
repo sync

compile.sh 编译

# 编译时使用python2
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 150
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 100
echo "正在清理"
make clobber
source ./build/envsetup.sh
# 版本根据需要修改
echo "选择编译版本"
lunch 24
# lunch
# 线程数根据处理器数量修改
echo "开始全量编译"
make -j4
