Android AOSP 源码编译 android5.1.1，并刷入手机

必备：

linux（本次使用centos7）

aosp（android5.1.1）

二进制驱动（官网下载）

设备：nexus5 LMY48M

openjdk 1.7.x

centos和ubuntu基本一样，均可用一下方法来完成编译

一、编译

1.驱动下载地址：https://developers.google.com/android/drivers#hammerhead

按照你的版本号来选择对应的驱动 LMY48M，如下图;

下载完成之后的到三个压缩包

解压这三个压缩包，得到三个.sh文件

将这个三个文件放到你的源码根目录，直接运行即可

执行以下命令：

./extract-broadcom-hammerhead.sh

之后，会提示没有权限，给它权限，执行下面命令：

chmod u+x extract-broadcom-hammerhead.sh

再运行

./extract-broadcom-hammerhead.sh

执行之后会让你阅读那些协议什么的，你只管拉倒最后即可，直至看到下面这行话

你再此句话后面，输入I ACCEPT 确认即可

其他两个.sh文件执行方法和这个一样，执行完成后，源码目录下会多处一个目录：vendor

2.进入aosp源码目录，执行下面命令，意思就是给他一个写内存，保证他可以顺利编译，当然不执行下面命令也是可以的，你内存如果多的话，不妨给他，有舍有得嘛。

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

3.也是在当前目录下，不用切换，执行以下命令：

source build/envsetup.sh

4.执行lunch，会出现以下列表

lunch

5.选择你的设备，我就选19了，执行命令：

6.开始编译（mack -jx的话，看你cup核数情况了，按照网上说的是来两倍为宜，我的配置不高，所以就-j2了）

mack -j2

编译后输出的文件都放在了源码根目录下的`out`文件中

二、刷机

1.将手机连接电脑，然后执行以下命令，确认已经连接上

adb devices

如图：即为连接上

如果显示以下证明已经连接上，可以进行后续操作了。

2.进入bootloader模式，执行以下命令

adb reboot bootloader

3.解锁

fastboot oem unlock

然后，按上下音量键选择YES选项，再按电源键确认就解锁成功了喽

如果提示你已经解锁，那么继续下一步

4.刷入镜像

fastboot -w flashall

然后就静静的等待，完成之后，手机会重启，这次时间会久一点，等待开机就可以了，刷机也就完成了

完成截图如下：

三.等待编译完成，编译过程中，会遇到各种各样的问题，比如

（1）：这个问题具体叫啥也不好说，我就不命名了，反正也不是很清楚

ninja: build stopped: subcommand failed.
make: *** [ninja_wrapper] error 1

这个问题首先你要确定你有没有jack-server，一半你刚下载下来的源码中，是没有的，你安装就可以。

怎样确认你有没有安装呢，你可以进入你源码的这个目录

cd prebuilts/sdk/tools

然后执行,意思是停止服务

./jack-admin stop-server

如果执行后，提示你
编译的时候可能会出现这个错误，第一次编译的话，它是没有安装jack-server的

所以你就要安装它。如果安装后，还是有问题，那就看问题三了，一般都会解决的。

2.fatal: fork: Cannot allocate memory

[  4% 2326/47944] host C++: libLLVMBitRead...lvm/lib/Bitcode/Reader/BitstreamReader.cppninja: fatal: fork: Cannot allocate memory
make: *** [ninja_wrapper] 错误 1

这个的话是无法分配内存，你把你虚拟机的内存调整下，调大点，还有，你的电脑也要保持做的运存空间，运存使用最好不要超过92%。

3.安装编译需要的依赖库，这个很重要的，这个能解决大部分错误，不然会有各种错误爆出，导致编译中断

centos的话使用yum安装即可：

$ sudo yum install -y gcc make libstdc++.i686 libstdc++-devel.i686 zlib-devel openssl-devel perl cpio expat-devel gettext-devel autoconf glibc.i686 glibc-devel.i686 zlib-devel.i686 libstdc++.i686 libX11-devel.i686 ncurses-devel.i686 ncurses-libs.i686 gperf flex gcc-c++ bison patch

如果你是Ubuntu的话执行下面的，前面的sudo的话看你在什么账户下的，root账户下的话，就不用了

sudo apt-get install -y git flex bison gperf build-essential libncurses5-dev:i386
sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib
sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386

sudo apt-get install lib32z-dev ccache

，这个问题因为已经到了86%了，处理问题一次，就需要好几小时时间，所以很坑。
