如何编译RK3399？

编译前准备: 环境搭建
安装openjdk8

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk

安装其他依赖库

sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev
  libesd0-dev libwxgtk2.8-dev squashfs-tools build-essential zip curl
  libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 libxml2-utils
  xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev
  lib32readline-gplv2-dev gcc-multilib libswitch-perl

sudo apt-get install gcc-arm-linux-gnueabihf
  libssl1.0.0 libssl-dev
  p7zip-full

安装碰到的问题:
libwxgtk2.8-dev无法安装的解决方法
16.04提供libwxgtk3.0-dev
sudo apt-get install libwxgtk3.0-dev

lib32readline-gplv2-dev无法安装的解决方法
vim /etc/apt/sources.list
结尾添加源地址：deb http://cz.archive.ubuntu.com/ubuntu trusty main
执行sudo apt-get update
然后sudo apt-get install lib32readline-gplv2-dev

使用 Firefly 官方脚本编译

• 单独编译kernel：
  ./FFTools/make.sh -k -j8
  
• 单独编译uboot：
  ./FFTools/make.sh -u -j8
  
• 单独编译android上层：
  ./FFTools/make.sh -a -j8
  
• 同时编译ubooot、kernel、android：
  ./FFTools/make.sh -j8
  
  

手动编译
编译前执行如下命令配置环境变量：可以加到.bashrc里再source一下.
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

• 编译kernel：
  cd ~/proj/firefly-rk3399/kernel/
  make ARCH=arm64 firefly_defconfig
  make -j8 ARCH=arm64 rk3399-firefly.img
  
• 编译uboot：
  cd ~/proj/firefly-rk3399/u-boot/
  make rk3399_box_defconfig
  make ARCHV=aarch64 -j8
  
• 编译android：
  cd ~/proj/firefly-rk3399/
  source build/envsetup.sh
  lunch rk3399_firefly_box-userdebug
  make -j8
  
  

编译tinycap
mmm external/tinyalsa/
编译好后一般在out/target/product/xxx/system/bin/tinycap

编译过程中碰到的问题


0, 编译kernel碰到的问题:

make kernel err

make[1]: *** [scripts/mod] Error 2

make: *** [scripts] Error 2

解决 =========================================
应该是arm-linux-gcc没有安装或者安装版本低于4.9引起.
重新安装
sudo apt-get install gcc-arm-linux-gnueabihf
同时记得进到kernel目录 , make clean一下.

1, - jdk要用openjdk 8 编译7.1的代码

2, jack-server问题: 参考
在编译7.1.1源码的时候，需要检查一下Jack-Server是否已经安装以及启动。
根据机器的RAM设置Jack-Server的VM大小，我机器是16G内存，所以设置8G左右VM。 修改prebuilts/sdk/tools/jack-admin 文件，找到变量JACK_SERVER_VM_ARGUMENTS位置在后面添加，添加参数 -Xmx8000M




进入prebuilts/sdk/tools 运行以下命令：
$ ./jack-admin start-server
如果提示没有安装的话，则运行以下命令,然后再次运行上面启动jack-server的命令。
$ ./jack-admin install-server jack-launcher.jar jack-server-4.8.ALPHA.jar

3, 参考

去除所有本地化的设置，让命令能正确执行，bash 执行：
export LC_ALL=C

4, 编译tinycap过程出现
mmm external/tinyalsa
Couldn’t locate the directory external/tinyalsa
原因是因为当前shell环境是zsh , 切换到bash即可 , 直接运行bash
然后source build/envsetup.sh 再lunch就可以执行mmm命令.

第0个问题，应该是python版本不对，用的python3 ，而应该用python2
