Ubuntu18.04 编译 Android10.0 系统环境，每次搞一个新电脑或环境，编译总要搞半天，虽然知道是环境安装的问题，但确实很烦和耗时，关键是报错各异。
思路： 网上找资料，首先要对齐Ubuntu 版本号，18.04， 20.04等，这个很关键，否则对不上。
最近弄的18.04，kernel都编译正常，一编译Android就挂了，啥错误提示都看不到，找了好多网页，总是好了。用最笨的办法解决。
sudo apt-get install git bc bison build-essential curl flex g++-multilib gcc-multilib gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm zip zlib1g-dev python
sudo apt-get install lib32ncurses5 lib32z1 libc6:i386 libstdc++6:i386
下面这个测试有效果，安装后，一定sudo apt-get update sudo apt-get uprade
sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig kpartx python-mako gcc-arm-linux-gnueabihf libssl-dev
