ubuntu 14.04.5 编译Android 4.4.4 r1源码（最新）

本文博客链接：http://www.jb51.cc/article/p-fxftmkft-bpy.html

吐槽：ubuntu系统真是让人又爱又恨，也有可能是VMware Workstation Pro虚拟机的原因；同一个版本的ubuntu系统在Oracle VM VirtualBox上安装很顺利没有多大的问题，但是在VMware Workstation Pro虚拟机上安装，就会出现各种奇葩的问题，为了配置一个自己用的顺手的ubuntu环境真是折腾死人，来来回回不下10次，而且还发现一个问题，按照别人的博客教程，同一个步骤，自己就是不能操作成功，总会出现这样那样的问题，有些作者的博客吧，自己也不实践一下网上照抄过来的，后来实践发现很多教程都是错的甚至是误导人的，只有极少数人是经过实践并分析出原因给出的解决方法。下面就记录一下，基于ubuntu 14.04.5(x64bit) 编译Android 4.4.4 r1源码遇到的坑以及解决的办法。

一、JDK安装

编译Android4.x的源码是不能用OpenJDK，需要用Oracle JDK 1.6，Oracle JDK1.7目前是不支持的；编译Android 5.x版本以后的源码不再能使用Oracle JDK，需要使用OpenJDK 7版本。从下载页http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html#jdk-6u45-oth-JPR，下载Linux x64bit版本Oracle JDK 1.60_45.

将从官网下载的jdk-6u45-linux-x64.bin 拷贝ubuntu 14.04.5系统的/home/androidcode/AndroidDevlop 路径下，执行解压：

cd /home/androidcode/AndroidDevlop
sudo chmod u+x jdk-6u45-linux-x64.bin
sudo ./jdk-6u45-linux-x64.bin

添加 Oracle JDK 1.60_45的路径到ubuntu系统的环境变量中：

sudo gedit /etc/profile

先打开全局环境变量添加文件/etc/profile，将jdk 1.60_45相关的环境变量添加到文件/etc/profile的末尾，然后保存/etc/profile文件，关闭gedit程序：

# 添加java环境变量
export JAVA_HOME=/home/androidcode/AndroidDevlop/jdk1.6.0_45
export JRE_HOME=${JAVA_HOME}/jre
export PATH=$PATH:${JAVA_HOME}/bin
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib

使用source更新下.profile文件：

source /etc/profile

执行命令java -version 看下jdk 1.60_45是否安装成功：

java -version

设置ubuntu系统默认jdk的扩展操作命令：

// 为Oracle jdk创建/usr/bin的符号链接（数字300 表示优先级）
sudo update-alternatives --install /usr/bin/java java /home/androidcode/AndroidDevlop/jdk1.6.0_45/bin/java 300  
sudo update-alternatives --install /usr/bin/javac javac /home/androidcode/AndroidDevlop/jdk1.6.0_45/bin/javac 300  
// 后面两项可以不配置  
sudo update-alternatives --install /usr/bin/javah javah /home/androidcode/AndroidDevlop/jdk1.6.0_45/bin/javah 300  
sudo update-alternatives --install /usr/bin/jar jar /home/androidcode/AndroidDevlop/jdk1.6.0_45/bin/jar 300  

// jdk默认版本切换命令  
sudo update-alternatives --config java
sudo update-alternatives --config javac

// 设置系统默认的JDK/JRE
sudo update-alternatives --set java /usr/bin/java java /home/androidcode/AndroidDevlop/jdk1.6.0_45/bin/java
sudo update-alternatives --set javac /usr/bin/javac javac /home/androidcode/AndroidDevlop/jdk1.6.0_45/bin/javac

update-alternatives命令的使用说明

1.功能作用
update-alternatives是dpkg的实用工具，用来维护系统命令的符号链接，以决定系统默认使用什么命令。
在Debian系统中，我们可能会同时安装有很多功能类似的程序和可选配置，如Web浏览器程序(firefox，konqueror)、窗口管理器(wmaker、Metacity)和鼠标的不同主题等。这样，用户在使用系统时就可进行选择，以满足自已的需求。
但对于普通用户来说，在这些程序间进行选择配置会较困难。update-alternatives工具就是为了解决这个问题，帮助用户能方便地选择自已喜欢程序和配置系统功能

2.位置
/usr/bin/update-alternatives

3.格式用法
update-alternatives [<选项> ...] <命令>

4.主要参数
Commands:
  --install <link> <name> <path> <priority>
    [--slave <link> <name> <path>] ...
                           在系统中加入一组替换项.
  --remove <name> <path>   从 <名称> 替换组中去除 <路径> 项.
  --remove-all <name>      从替换系统中删除 <名称> 替换组.
  --auto <name>            将 <名称> 的主链接切换到自动模式.
  --display <name>         显示关于 <名称> 替换组的信息.
  --query <name>           machine parseable version of --display <name>.
  --list <name>            列出 <名称> 替换组中所有的可用替换项.
  --get-selections         list master alternative names and their status.
  --set-selections         read alternative status from standard input.
  --config <name>          列出 <名称> 替换组中的可选项，并就使用其中哪一个，征询用户的意见.
  --set <name> <path>      将 <路径> 设置为 <名称> 的替换项.
  --all                    对所有可选项一一调用 --config 命令.

<link> 是指向 /etc/alternatives/<名称> 的符号链接>.(e.g. /usr/bin/pager)
<name> 是该链接替换组的主控名.(e.g. pager)
<path> 是替换项目标文件的位置.(e.g. /usr/bin/less)
<priority> 是一个整数，在自动模式下，这个数字越高的选项，其优先级也就越高.

Options:
  --altdir <directory>     指定不同的可选项目录.
  --admindir <directory>   指定不同的管理目录.
  --log <file>             设置log文件.
  --force                  allow replacing files with alternative links.
  --skip-auto              skip prompt for alternatives correctly configured in automatic mode (relevant for --config only)
  --verbose                详尽的操作进行信息，更多的输出.
  --quiet                  安静模式，输出尽可能少的信息.
  --help                   显示本帮助信息.
  --version                显示版本信息.
  
5.应用实例
1、列出可用的候选命令
update-alternatives --list java

2、显示和修改实际指向的候选命令,sudo update-alternatives --config java

3、配置系统上所有的候选命令
sudo update-alternatives --all

4、显示一个命令链接的所有可选命令
update-alternatives --display editor

5、将 <名称> 的主链接切换到自动模式
sudo update-alternatives --auto editor

6、在系统中加入一组替换项
sudo update-alternatives --install x-cursor-theme x-cursor-theme /etc/X11/cursors/Gold.theme 70

二、安装编译依赖的软件

关于编译Android源码需要的依赖库文件和需要的环境条件具体的可以参考google官网的文档https://source.android.com/source/requirements.html。下面的命令是google官网给出的，编译Android 4.4.4 r1源码需要安装的依赖库文件：

sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dri:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 dpkg-dev  
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

在uhuntu的命令行终端执行上面命令，很遗憾，出现下面的错误：

The following packages have unmet dependencies:
 unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
                        Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Error,pkgProblemResolver::Resolve generated breaks,this may be caused by held packages.

博文http://blog.csdn.net/dev_linux/article/details/45276403的作者给出的解决方法给了我启发，后来我发现在命令行终端执行sudo apt-get install libcheese-gtk23 libcheese7 命令，提示libcheese-gtk23 libcheese7已经存在了，只是版本和这里安装需要的版本不符，执行下面的命令就可以解决。但是也有风险，很可能导致ubuntu系统不能进入图形界面因为一些系统的程序文件也被卸载移除了，需要在命令行进行ubuntu图形界面的修复，具体的参考：http://www.jb51.cc/article/p-fxjvvifk-bpy.html。

sudo apt-get remove   libcheese-gtk23 libcheese7
sudo apt-get install  libcheese-gtk23 libcheese7

解决方法：

# I'm just being cautIoUs because the last time I run "sudo apt-get autoremove" it screwed me up.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
# without autoremove command,then,if you get no errors,to install 32bit libraries (as it appears not to drag them in):
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
# then:
sudo apt-get install steam -y

参考链接：https://ubuntuforums.org/showthread.php?t=2268104&page=2

2）出现上文中提到的相同问题的讨论

解决办法1

sudo apt-get install libglew-dev libcheese7 libcheese-gtk23 libclutter-gst-2.0-0 libcogl15 libclutter-gtk-1.0-0 libclutter-1.0-0

解决办法2
也有网友提到是ubuntu的源的问题，采用下面的方法解决的问题：

# So the problem has been with the dependencies,namely
# libegl1-mesa-drivers depending on libglapi-mesa ( = 10.1.3-0ubuntu0.3 ) (maybe should be >=)
# I have added the xorg-edgers PPA again and then properly downgraded with ppa-purge as so:

sudo add-apt-repository ppa:xorg-edgers/ppa && sudo apt-get update
sudo ppa-purge  ppa:xorg-edgers/ppa && sudo apt-get update

# and now I have all packages from xorg-edgers removed and system settings dialog opens up :)

参考链接： http://askubuntu.com/questions/575548/system-settings-stopped-showing-up

Note that：上面提供的解决方法，虽然有些能够解决"libcheese-gtk23" 和 "libcheese7" 不能能安装成功的问题，但是即使解决了这个问题，接下来又会产生新的问题也就是Unmet dependencies for libcheese-gtk23 and libcheese7 会影响到ubuntu 14.04系统的unity-control-center 也就是上文提到的使用sudo apt-get remove libcheese-gtk23 libcheese7和sudo apt-get install libcheese-gtk23 libcheese7解决问题，重启系统会出现不能进入ubuntu系统图形登陆界面，只出现命令行的登陆界面，需要修复ubuntu系统的图形登陆界面，纵然ubuntu系统图形登陆界面修复成功，打开ubuntu系统的system settings 会出现图标变少的情况，原来很多常用的图标都没有了，需要修复，其实这是ubuntu 14.04系统的bug，具体的讨论参考地址：https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1428972。

解决方法：

For Comment #9,I had the same issue when trying to install cuda 7,and doing
sudo apt-get install libglew-dev libcheese7 libcheese-gtk23 libclutter-gst-2.0-0 libcogl15 libclutter-gtk-1.0-0 libclutter-1.0-0
fixed it for me.

再次执行前面安装编译依赖库命令，再次出现下面的错误：

The following packages have unmet dependencies:
 build-essential : Depends: g++ (>= 4:4.4.3) but it is not going to be installed
 g++-multilib : Depends: gcc-multilib (>= 4:4.8.2-1ubuntu6) but it is not going to be installed
                Depends: g++ (>= 4:4.8.2-1ubuntu6) but it is not going to be installed
                Depends: g++-4.8-multilib (>= 4.8.2-5~) but it is not going to be installed
E: Unable to correct problems,you have held broken packages.

经过网络查询发现是依赖库安装源地址旧了的缘故，需要添加下载源地址然后更新安装源地址，具体的可以参考网址： http://askubuntu.com/questions/685669/install-g-ubuntu-14-04-depends-g-4-8-4-8-2-5-but-it-is-not-going-to-b给出的解决方法：

1.执行下面的命令备份原来的安装源sources.list

sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

2.执行lsb_release -a 命令查看当前ubuntu系统的release版本号

lsb_release -a

3.通过上面获取到的ubuntu系统的发布号 14.04 拼接成下面的URL地址，登陆下面这个URL地址，查看该版本的ubuntu有效的安装源地址：

http://wiki.ubuntu.org.cn/Template:14.04source

4.执行sudo gedit /etc/apt/sources.list 命令，打开/etc/apt/sources.list文件，将下面的安装源地址添加到/etc/apt/sources.list文件的末尾，然后保存文件，关闭gedit：

sudo gedit  /etc/apt/sources.list

deb http://cn.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
##测试版源
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse
# 源码
deb-src http://cn.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
##测试版源
deb-src http://cn.archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse
# Canonical 合作伙伴和附加
deb http://archive.canonical.com/ubuntu/ trusty partner
deb http://extras.ubuntu.com/ubuntu/ trusty main

5.更新安装源地址，使其生效：

sudo apt-get update

6.安装g++和g++-multilib

sudo apt-get install g++
sudo apt-get install g++-multilib

再次执行安装依赖库文件的命令，就能执行成功了：

sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dri:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 dpkg-dev  
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

三、编译Android 4.4.4 r1的源码

1）初始化编译环境

. build/envsetup.sh  或  source build/envsetup.sh

2）选择编译目标版本

lunch的方式有很多中，可以使用lunch命令查看，我使用最常用的

lunch 9

3）编译

1.make后面可以更参数：如你的机器时双核，每核双线程的话，使用make -j4,这样速度更快，但编译时使用的内存也更多
2.make失败或停止后，可以使用make -k 继续编译

make -j16

四、后记

前面由于执行sudo apt-get remove libcheese-gtk23 libcheese7可能导致重启ubuntu系统不能进入图形界面的情况，因此需要执行下面的操作进行修复：

1、进入了命令行界面，输完用户名和密码
2、重装gdm，sudo apt-get install gdm
3、设置启动界面的风格：dpkg -reconfigure gdm
4、重启reboot可登录。

ubuntu登陆界面修复成功以后，进入ubuntu系统，打开命令行终端，执行下面的操作，恢复ubuntu最初的登陆界面：

sudo apt-get install  lightdm
dpkg -reconfigure lightdm

基于前面的原因ubuntu系统的system setting中的图标可能会消失，需要修复，执行下面的命令：

sudo apt-get install unity-control-center

五、谷歌官方给出的编译Android源码的说明

怪不得自己编译Android源码各种出错呢，原来是根本就不看谷歌官方网站给出的各种说明，到头来各种出错找不到原因。

Hardware requirements

Your development workstation should meet or exceed these hardware requirements:

A 64-bit environment is required for Gingerbread (2.3.x) and newer versions,including the master branch. You can compile older versions on 32-bit systems.
At least 100GB of free disk space for a checkout,150GB for a single build,and 200GB or more for multiple builds. If you employ ccache,you will need even more space.
If you are running Linux in a virtual machine,you need at least 16GB of RAM/swap

Software requirements

TheAndroid Open Source Project (AOSP)masterbranch is traditionally developed and tested on Ubuntu Long Term Support (LTS) releases,but other distributions may be used. See the list below for recommended versions.

You workstation must have the software listed below. SeeEstablishing a Build Environmentfor additional required packages and the commands to install them.

Operating system

Android is typically built with a GNU/Linux or Mac OS operating system. It is also possible to build Android in a virtual machine on unsupported systems such as Windows.

GNU/Linux

Android 6.0 (Marshmallow) - AOSP master: Ubuntu 14.04 (Trusty)
Android 2.3.x (Gingerbread) - Android 5.x (Lollipop): Ubuntu 12.04 (Precise)
Android 1.5 (Cupcake) - Android 2.2.x (Froyo): Ubuntu 10.04 (Lucid)

Mac OS (Intel/x86)

Android 6.0 (Marshmallow) - AOSP master: Mac OS v10.10 (Yosemite) or later with Xcode 4.5.2 and Command Line Tools
Android 5.x (Lollipop): Mac OS v10.8 (Mountain Lion) with Xcode 4.5.2 and Command Line Tools
Android 4.1.x-4.3.x (Jelly Bean) - Android 4.4.x (KitKat): Mac OS v10.6 (Snow Leopard) or Mac OS X v10.7 (Lion) and Xcode 4.2 (Apple's Developer Tools)
Android 1.5 (Cupcake) - Android 4.0.x (Ice Cream Sandwich): Mac OS v10.5 (Leopard) or Mac OS X v10.6 (Snow Leopard) and the Mac OS X v10.5 SDK

Java Development Kit (JDK)

Please note,since there are no available supported OpenJDK 8 packages for Ubuntu 14.04,the Ubuntu 15.04 packages must be installed manually. SeeJDK for Ubuntu LTS 14.04for precise instructions.

The master branch of Android in AOSP: Ubuntu -OpenJDK 8,Mac OS -jdk 8u45 or newer
Android 5.x (Lollipop) - Android 6.0 (Marshmallow): Ubuntu -OpenJDK 7,Mac OS -jdk-7u71-macosx-x64.dmg
Android 2.3.x (Gingerbread) - Android 4.4.x (KitKat): Ubuntu -Java JDK 6,Mac OS -Java JDK 6
Android 1.5 (Cupcake) - Android 2.2.x (Froyo): Ubuntu -Java JDK 5

Key packages

Python 2.6 -- 2.7 frompython.org
GNU Make 3.81 -- 3.82 fromgnu.org; Android 3.2.x (Honeycomb) and earlier will need torevert from make 3.82to avoid build errors
Git 1.7 or newer fromgit-scm.com

谷歌官方参考链接： https://source.android.com/source/requirements.html

Installing required packages (Ubuntu 14.04)

You will need a 64-bit version of Ubuntu. Ubuntu 14.04 is recommended.

$ sudo apt-get install git-core gnupg flex bison gperf buildessential \
 zip curl zlib1gdev gccmultilib g++-multilib libc6devi386 
 lib32ncurses5dev x11protocoredev libx11dev lib32zdev ccache 
 libgl1mesadev libxml2utils xsltproc unzip

Note:To use SELinux tools for policy analysis,also install thepython-networkxpackage.

Note:If you are using LDAP and want to run ART host tests,0); line-height:14px">libnss-sss:i386package.

Installing required packages (Ubuntu 12.04)

You may use Ubuntu 12.04 to build older versions of Android. Version 12.04 is not supported on master or recent releases.

 install git gnupg flex bison gperf build
 zip curl libc6dev libncurses5:i386 x11protodev 
 libx11i386 libreadline6i386 libgl1glxdev gmultilib mingw32 tofrodos 
 pythonmarkdown libxml2utils xsltproc zlib1gi386
$ sudo ln s /usrlibi386linuxgnulibGL.so.1 so

The following instructions to build the Android source tree apply to all branches,includingmaster. The basic sequence of build commands is as follows:

Note:If you're building Android 6.0 or later,please seeCompiling with Jackfor information on this new default toolchain.

Obtain proprietary binaries

AOSP cannot be used from pure source code only and requires additional hardware-related proprietary libraries to run,such as for hardware graphics acceleration. See the sections below for download links andDevice binaries requirementsfor additional resources.

Download proprietary binaries

You can download official binaries for the supported devices running tagged AOSP release branches fromGoogle's Nexus driver page. These binaries add access to additional hardware capabilities with non-open source code. To instead build the AOSP master branch,use theBinaries Preview for Nexus Devices. When building the master branch for a device,use the binaries for themost recent numbered releaseor with the most recent date.

Extract proprietary binaries（如何将google提供的设备驱动相关的文件 添加到Android源码中参与编译）

Each set of binaries comes as a self-extracting script in a compressed archive. Uncompress each archive, run the included self-extracting script from the root of the source treethen confirm that you agree to the terms of the enclosed license agreement.The binaries and their matching makefiles will be installed in thevendor/hierarchy of the source tree.

Clean up

To ensure the newly installed binaries are properly taken into account after being extracted,delete the existing output of any prevIoUs build using:

$ make clobber

Set up environment

Initialize the environment with theenvsetup.shscript. Note that replacingsourcewith.(a single dot) saves a few characters,and the short form is more commonly used in documentation.

$ source buildenvsetupsh

$  buildsh

Choose a target

Choose which target to build withlunch. The exact configuration can be passed as an argument. For example,the following command:

$ lunch aosp_armeng

refers to a complete build for the emulator,with all debugging enabled.

If run with no argumentslunchwill prompt you to choose a target from the menu.

All build targets take the formBUILD-BUILDTYPE,where theBUILDis a codename referring to the particular feature combination.

The BUILDTYPE is one of the following:

Buildtype	Use
user	limited access; suited for production
userdebug	like "user" but with root access and debuggability; preferred for debugging
eng	development configuration with additional debugging tools

For more information about building for and running on actual hardware,seeRunning Builds.

Build the code

Running Buildsfor detailed instructions on building Android.

Build everything withmake. GNU make can handle parallel tasks with a-jNargument,and it's common to use a number of tasks N that's between 1 and 2 times the number of hardware threads on the computer being used for the build. For example,on a dual-E5520 machine (2 cpus,4 cores per cpu,2 threads per core),the fastest builds are made with commands betweenmake -j16andmake -j32.

$ make j4

Run it!

You can either run your build on an emulator or flash it on a device. Please note that you have already selected your build target withlunch,and it is unlikely at best to run on a different target than it was built for.

Note:Remember toobtain proprietary binariesor your build will not boot successfully on your target hardware. If you obtain binary blobs at this point you will need to unpack them,make clobberand rebuild.

Flash with fastboot

To flash a device,you will need to usefastboot,which should be included in your path after a successful build. SeeFlashing a devicefor instructions.

Emulate an Android Device

The emulator is added to your path automatically by the build process. To run the emulator,type:

$ emulator

六、Ubuntu虚拟机系统VMware Tools的安装（顺便记录一下）

1.通过VMware Workstation Pro虚拟机的菜单栏虚拟机(M)--->安装VMware Tools(T)，点击安装VMware Tools虚拟机增强工具，此时在ubuntu studio 16.04.1 64bit系统的桌面，会生成一个VMware Tools的图标，点击进去会发现VMware Tools的安装包VMwareTools-10.0.0-2977863.tar.gz如下图，将其拷贝一份到ubuntu studio 16.04.1 64bit系统的桌面上。

2.打开终端对VMwareTools-10.0.0-2977863.tar.gz 进行解压

命令：

tar -xzvf VMwareTools-10.0.0-2977863.tar.gz

3.进入VMwareTools-10.0.0-2977863.tar.gz解压后的文件目录vmware-tools-distrib，su权限执行./vmware-install.pl ，按照VMwareTools的安装提示一路回车直到VMwareTools安装完成，然后reboot重启系统。

命令：

cd vmware-tools-distrib
sudo ./vmware-install.pl

reboot
