MTK Android 编译环境搭建总结

MTK Android 编译环境搭建总结

• 环境部署
  基本环境需求：
  硬盘： 大于200G
  内存： 大于16G
  OS: ubuntu14.04， ubuntu16.04， ubuntu18.04
  否则空间或内存不足，导致编译错误或编译时间太长。
  测试平台： MTK P23
  1、添加源/etc/apt/sources.list
  14.04：
  deb http://archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
  deb http://archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
  deb http://archive.ubuntu.com/ubuntu/ trusty-sercurity main restricted universe multiverse
  16.04：
  deb http://archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse
  deb http://archive.ubuntu.com/ubuntu/ xenial-updates main restricted universe multiverse
  deb http://archive.ubuntu.com/ubuntu/ xenial-sercurity main restricted universe multiverse
  18.04：
  deb http://archive.ubuntu.com/ubuntu/ bionic main restricted universe multiverse
  deb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted universe multiverse
  deb http://archive.ubuntu.com/ubuntu/ bionic-sercurity main restricted universe multiverse
  之后更新源：sudo apt-get update
  2、安装package
  sudo apt-get install bison g+±multilib git gperf libxml2-utils make python-networkx zlib1g-dev:i386 zip build-essential build-essential flex mingw32 tofrodos libswitch-perl openjdk-8-jdk
  3、安装jdk以及配置java
  sudo add-apt-repository ppa:openjdk-r/ppa
  sudo apt-get update
  sudo apt-get install openjdk-8-jdk
  sudo update-alternatives --config java
  sudo update-alternatives --config javac
  4、install xrdp
  sudo apt-add-repository ppa:ubuntu-mate-dev/ppa
  sudo apt-add-repository ppa:ubuntu-mate-dev/trusty-mate
  sudo apt-get update
  sudo apt-get install ubuntu-mate-core ubuntu-mate-desktop
  5、开始编译工作，设置环境变量
  source ./build/envsetup.sh
  6、选择编译工程
  lunch
  如选择43，编译t758工程的user版本, full_t758_public_pcba_63_o1-user
  7、编译
  全部编译：make -j8
  编译内核： make -j8 kerenl
  编译LK: make -j8 lk
  清除： make clean
  8、编译输出
  编译成功会提示：
  build success
  输出位置： out/target/product
  OUT 目录接近100G左右。
  9、内存不足提示错误解决方法
  Try increasing heap size with java option ‘-Xmx’
  ninja: build stopped: subcommand failed.
  make: *** [ninja_wrapper] Error 1

一般在命令行执行以下三条语句再编译就行了。

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx16g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server
