首先准备一个linux环境，本人使用的是ubuntu18.04
1.硬盘空间最好200G＋
2.更新下系统到最新。sudo apt-get update ;sudo apt-get upgrade
3.准备压缩包rk3326sdk8.1-7072-20190121.tar.gz
4.解压出来 tar -zxvf rk3326sdk8.1-7072-20190121.tar.gz. 需要很久17G+的压缩包
5.安装java8 sudo apt-get update;sudo apt-get install openjdk-8-jdk
6.配置java环境
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
7.安装依赖包
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl
zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev
x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils
xsltproc unzip
8.安装lz4c ，解决下图问题 sudo apt-get install liblz4-tool
缺少第三方库
类似问题 sudo apt-get install m4
9.安装交叉编译的库，不然会报错sudo apt-get install gcc-multilib
10.扩展下swap，8g内存一下的会报内存不足，最好交换空间设置16G

11.这个错误的话，改下内存大小
FAILED: out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/with-local/classes.dex
/bin/bash out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/with-local/classes.dex.rsp

GC overhead limit exceeded.
Try increasing heap size with java option '-Xmx<size>'.
解决方案
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server
12.这个错误 _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))’ failed.
解决方案
添加完之后记得source .bashrc 不然不生效

13没有python。。。。
就装个python --------- sudo apt-get install python
花了一天终于编好了，最好用服务器编CPU核越多越好，内存得8G+，硬盘 至少200G，编完只剩30G（删除压缩包的情况）
加油
