CM12.1/13.0编译教程

环境搭建

1.安装64位Ubuntu系统（实体安装、虚拟机安装均可）

注意：要求机器至少4G内存（虚拟机至少分配4G内存），硬盘至少100G空间（源码20G+，编译后整个目录约60~70G）
安装方法请百度~

2.更新系统至最新版本，在终端下输入

sudo apt-get update
sudo apt-get upgrade

 3.安装编译必需软件包

sudo apt-get install

For both 32-bit & 64-bit systems, you'll need:

bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these:

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

libwxgtk2.8-dev → libwxgtk3.0-dev
openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

• CyanogenMod 7 - 9: Sun/Oracle Java SE 1.6
• CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
• CyanogenMod 10.2 - 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
• CyanogenMod 12.0 - 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

1. Obtain OpenJDK 1.7 from the openjdk-r PPA
2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: 

3. export EXPERIMENTAL_USE_JAVA8=true

4.建立repo命令

mkdir -p ~/bin

curl https://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

chmod a+x ~/bin/repo echo "export PATH=~/bin:$PATH" >> ~/.bashrc

注意，第二行要从谷歌那里下载repo小程序，国内网络你懂的，可以在浏览器上面挂个代理通过以下地址下载好，拷贝到~/bin/repo，再执行第三行和第四行命令,当然，最好的办法是：

更新/替换系统 hosts，轻松访问国外站点

同步源码

1.新建一个储存源码的文件夹，这里以~/android/cm为例

mkdir ~/android/cm
cd ~/android/cm

2.初始化源码目录

repo init -u git://github.com/CyanogenMod/android.git -b cm-12.1

若初始化失败，请参考http://www.cnblogs.com/dinphy/p/5669384.html

3.添加红米3专用文件目录

mkdir ~/android/cm/.repo/local_manifests
gedit ~/android/cm/.repo/local_manifests/ido.xml

把以下内容复制进去

<?xml version="1.0" encoding="utf-8"?>
<manifest>
    <!-- Device repos -->
    <project name="dinphy1205/android_device_xiaomi_ido-cm12.1" path="device/xiaomi/ido" revision="cm-12.1" remote="github" />
    <project name="dinphy1205/proprietary_vendor_xiaomi_ido-12.1" path="vendor/xiaomi" revision="cm-12.1" remote="github" />
    <project name="dinphy1205/android_kernel_xiaomi_msm8916-12.1" path="kernel/xiaomi/ido" revision="cm-12.1" remote="github" />
    <project name="CyanogenMod/android_device_qcom_common" path="device/qcom/common" revision="cm-12.1" remote="github" />
    <!-- Other --> 
    <project name="CyanogenMod/android_external_mm-dash" path="external/mm-dash" revision="cm-12.1" remote="github" />
</manifest>

13.0的复制如下：

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
    <!-- Device repos -->
    <project path="device/xiaomi/ido" name="dinphy1205/android_device_xiaomi_ido-1" revision="cm-13.0" />
    <project path="kernel/xiaomi/ido" name="dinphy1205/android_kernel_xiaomi_ido" revision="cm-13.0" />
    <project path="vendor/xiaomi/ido" name="dinphy1205/android_vendor_xiaomi_ido-1" revision="cm-13.0" />
　　    <project path="device/qcom/common" name="CyanogenMod/android_device_qcom_common" revision="cm-13.0" /> 
    <!-- Other --> 
    <project path="external/sony/boringssl-compat" name="CyanogenMod/android_external_sony_boringssl-compat" revision="cm-13.0" /> 
    <project path="external/stlport" name="CyanogenMod/android_external_stlport" revision="cm-13.0" /> 
</manifest>

4.针对国内网络环境的处理（略自己使用VPN或者SS，教程请百度）

5.拉取代码（需要下载约十几个G的内容，花费时间参考各自网速）

repo sync -c -f -j8 --force-sync --no-clone-bundle

如果中间断网了，或者出错了，重新repo sync一下就可以继续了~

6.获取预编译的部分文件

cd ~/android/cm/vendor/cm
./get-prebuilts

如果已经有了，这步跳过

编译ROM
1.初始化编译环境

cd ~/android/cm
. build/envsetup.sh
lunch cm_ido-userdebug

2.编译ROM（我笔记本下面虚拟机花费时间约2小时，取决于个人电脑性能）

mka ido

or

brunch cm_ido-userbug

注意：目前编译刚开始出现下面几行是正常现象，不影响的~

1. find: 'src': No such file or directory
2. find: 'phone/java': No such file or directory
3. find: 'dummy': No such file or directory

再次编译
1.建议每次编译都要把上一次编译的内容清除，否则有可能出现莫名其妙的问题

1. make clobber

2.再次同步源码到最新版本

repo sync -c -f -j8 --force-sync --no-clone-bundle

3.初始化编译环境

. build/envsetup.sh
lunch cm_ido-userdebug

4.编译ROM

mka ido

一点贴士

1、机型文件device、kernel、vendor放置路径

1）device

device/xiaomi/ido

2）kernel

kernel/xiaomi/msm8916

3）vendor

vendor/xiaomi/ido

2、开启ccache，加速编译过程

$ echo "export USE_CCACHE=1" >> ~/.bashrc
$ ~/cm/prebuilts/misc/linux-x86/ccache/ccache -M 50G
