背景

编译6.0.1版本自己刷机到nexus 5x中

代码下载

这一步忽略，方法很多，我们直接开始编译遇到的问题。

遇到问题和解决方法

编译6.0系统需要openjdk 7

编译5.1系统需要jdk7，如果需要编译5.1的后面再出文章吧。

编译前提

删除源码目录下所有git

find ./ -name ".git" | xargs rm -rf

//大小
du -sh -BG

下载openjdk7

信不过网盘的可以去这里下

sudo tar zxvf openjdk-7u75-b13-linux-x64-18_dec_2014.tar.gz -C /opt
# 修改profile文件
sudo gedit /etc/profile

# 加入下面的配置
export JAVA_HOME=/opt/java-se-7u75-ri
export JRE_HOME=${JAVA_HOME}/jre 
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib 
export PATH=${JAVA_HOME}/bin:$PATH

# 更新profile文件
source /etc/profile

继续修改其他mk文件

sudo gedit build/envsetup.sh
# 搜索  ANDROID_SET_JAVA_HOME
# 将刚才解压的jdk路径粘贴到下方的 JAVA_HOME 变量中

比如我的修改之后

sudo gedit build/core/main.mk

注释这一句，让脚步正常，不能断。

图片描述

继续修改：

在源代码的根目录下找到 build/core/clang/HOST_x86_common.mk文件，打开文件找到 CLANG_CONFIG_x86_LINUX_HOST_EXTRA_ASFLAGS 的定义，在后面增加一行

1
-B$($(clang_2nd_arch_prefix)HOST_TOOLCHAIN_FOR_CLANG)/x86_64-linux/bin

编译之后，可能遇到的错误，但是这是我的，错误后面有解决方法。。

虚拟机配置了8g内存，几年前的台式机配置编译1.5小时这样。

如果配件都装好了，命令流程就这样的。
