1、构建编译环境
写在开头：因为sync源码一直失败，在网上找了别人汇总的各版本源码，步骤参照1.3，在这里直接下载就好

1.1 虚拟机实现
搭建虚拟机运行环境
这里使用PD虚拟机进行构建的ubuntu 16.04环境
# download
http://mirrors.aliyun.com/ubuntu-releases/16.04/
#安装，配置国内源</pre>
1.1.1 环境配置
sudo apt-get install git
git config –global user.email ""
git config –global user.name ""
# https://github.com/mikecriggs/ez-aosp
git clone git://github.com/mikecriggs/ez-aosp.git ez-aosp
cd ez-aosp
./ez-aosp.sh
EZ AOSP is a simple automated and user input driven tool for Ubuntu Linux LTS 16.04+ for an easy setup of an AOSP (Android Open Source Project) build environment.
1.1.2 AOSP build
- repo
mkdir ~/bin
PATH=~/bin:$PATH
curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o ~/bin/repo #使用tuna的git-repo镜像
chmod a+x ~/bin/repo
vim ~/bin/repo
# 将这行
REPO_URL = 'https://gerrit.googlesource.com/git-repo'
# 改为这行
REPO_URL = 'https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'</pre>
- Aosp 7.1
mkdir aosp
cd aosp
# repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-7.1.2_r36
repo sync
1.2 Docker
docker pull tedwang/aosp-v4:latest
docker search到的应该都是类似的东西，随便jdk版本选择一个pull到本地
Docker门外汉，查看Dockerfile文件应该是直接对ubuntu的公共镜像进行配置，有jdk有g++，可以直接把源码拉过去编译，免去自己配置
# dockerfile一般有以下信息
RUN apt-get update && apt-get install -y make \
gcc-arm-linux-gnueabi gcc lib32ncurses5 \
lib32stdc++6 lib32ncurses5 lib32bz2-1.0 \
lib32z1 u-boot-tools fakeroot libncurses5-dev \
python bison flex xsltproc gperf g++ lzma zip \
libxml2-utils git busybox
ADD jdk-6u31-linux-x64.bin /usr/java/jdk-6u31-linux-x64.bin
- 启动镜像
docker run --name='AOSP_New' -it --rm -v ~/Docker/Android/Aosp4:/aosp fanyinmeng/ubuntu14-android4-build-env-docker
-v 本地文件夹：镜像环境文件夹
将下载的源码复制到本地文件夹，在/aosp中查看
2、 编译
- $ source build/envsetup.sh
root@faf8b93fc475:/aosp/android-4.0.4_r1# source build/envsetup.sh
including device/moto/stingray/vendorsetup.sh
including device/moto/wingray/vendorsetup.sh
including device/samsung/crespo/vendorsetup.sh
including device/samsung/crespo4g/vendorsetup.sh
including device/samsung/maguro/vendorsetup.sh
including device/samsung/toro/vendorsetup.sh
including device/samsung/torospr/vendorsetup.sh
including device/samsung/tuna/vendorsetup.sh
including device/ti/panda/vendorsetup.sh
including sdk/bash_completion/adb.bash
- $ lunch
编译前对部分文件进行修改（我的环境是 tedwang/aosp-v4:latest + android4.0.4.r1；环境不同会出现各种不同的奇奇怪怪的错误，参见https://blog.csdn.net/zhangwenhaojf40it/article/details/78110106）
make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o] Error 1
make: *** Waiting for unfinished jobs....
$ vim build/core/combo/HOST_linux-x86.mk
修改源码目录下/build/core/combo/HOST_linux-x86.mk文件：
将以下语句
HOST_GLOBAL_CFLAGS+= -D_FORTIFY_SOURCE=0
修改为
HOST_GLOBAL_CFLAGS+= -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libMesa_intermediates/src/glsl/linker.o] Error 1
make: *** Waiting for unfinished jobs....
$ vim external/mesa3d/src/glsl/linker.cpp
Add '#include <stddef.h>' to list of includes
make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/liboprofile_pp_intermediates/arrange_profiles.o] Error 1
make: *** Waiting for unfinished jobs....
$ vim external/oprofile/libpp/format_output.h
Remove 'mutable' from 'mutable counts_t & counts;' on line 94:
make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libgtest_host_intermediates/gtest-all.o] Error 1
$ vim external/gtest/include/gtest/internal/gtest-param-util.h
添加：#include <cstddef>
make: *** [out/host/linux-x86/obj/EXECUTABLES/test-librsloader_intermediates/test-librsloader] Error 1
make: *** Waiting for unfinished jobs....
$ vim external/llvm/llvm-host-build.mk
add "LOCAL_LDLIBS := -lpthread -ldl"
- $ make -j4
核心数*2
编译了2天，终于是完成了，各种错误。
$ mmm development/tools/idegen/
$ sh ./development/tools/idegen/idegen.sh
获得 android.iml android.ipr
Tips
命令删除所有以前编译操作的已有输出：
make clobber
Docker环境中中断需要重新执行下列命令，不然会报 not found
$ source build/envsetup.sh
$ lunch
