高通845代码迁移后开发环境如何搭建及遇到的BUG

一、首先为了不出更多问题使用Ubuntu16.04系统，推荐虚拟机方便一次搭建，迁移方便

首先修改阿里apt源

见帖子ubuntu镜像-ubuntu下载地址-ubuntu安装教程-阿里巴巴开源镜像站

sudo vi /etc/apt/sources.listsudo apt-get update
sudo apt-get upgrade

Make bash in the default shell (Android build scripts contain the bash shell

dependencies that require the system default shell /bin/sh to invoke bash) using

one of the following options:

Reconfigure the package.
Use the following command:sudo dpkg-reconfigure dash
Type No.  Change the symlink /bin/sh→dash to /bin/sh→bash using the following
commands:sudo rm /bin/shsudo ln -s /bin/bash /bin/sh

然后运行下面的脚本配置环境，保存为.sh文件，然后运行两次

#!/bin/sh#Ubuntu 16.04
sudo apt install git -y
sudo apt-get install openssh-server -y
sudo /etc/init.d/ssh restart#ssh-keygen -t rsa -C "tully.wang@goertek.com"

sudo apt install gcc-multilib -y
sudo apt install aptitude -y
sudo apt install subversion -y
sudo apt install htop -y
sudo apt install curl -y

为预防出现错误xmllint: command not found

sudo apt-get install  libxml2-utils

为确保gcc、g++版本为4.9

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 40
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 20
gcc -v

为预防代码默认下载好后，编译路径被记下了，存放在了文件里bootable/bootloader/edk2/Conf/BuildEnv.sh，使用make clean　没办法清掉.

可以验证下，进入报错目录: bootable/bootloader/edk2 使用如下命令

. edksetup.sh

结果

WORKSPACE: /home/sdduser/code/android_O/bootable/bootloader/edk2
EDK_TOOLS_PATH: /local/android_O/bootable/bootloader/edk2/BaseTools
CONF_PATH: /home/sdduser/code/android_O/bootable/bootloader/edk2/Conf

可以看到BaseTools路径:EDK_TOOLS_PATH 还是之前的路径. 解决办法, 在edk2目录下执行:

rm -rf Conf/BuildEnv.sh
unset EDK_TOOLS_PATH
. ./edksetup.sh BaseTools

进入 BaseTools目录:

make clean

就不再报abl 编译错误了

编译7源码时，报错：SSL error when connecting to the Jack server. Try ‘jack-diagnose‘

Remove TLSv1, TLSv1.1 from jdk.tls.disabledAlgorithms in
/etc/java-8-openjdk/security/java.security file
Restart the jack server:
cd /prebuilts/sdk/tools/
./jack-admin kill-server
./jack-admin start-server

source build/envsetup.sh

lunch xx

重新编译: make -j8 2>&1 | tee build.log
注意如果遇到错误但是却找不到哪错了，要用单线程编译，这样就会在错误的地方中断

make -j1 2>&1 | tee build.log

非常方便找到问题
