Arch Compile Env

Arch Linux编译Android rom的环境

---

环境包准备

首先，我们得用bash, 像zsh这样的会在out过程出错，只推荐在编译时至少用bash
先声明自己

git config --global user.name "$urusername"
git config --global user.email "$urmailaddr"

其次，安装需要的基本的包

yay -S base-devel multilib-devel gcc repo git gnupg gperf sdl wxwidgets-common wxwidgets-gtk2 squashfs-tools curl ncurses zlib schedtool perl-switch zip unzip libxslt bc rsync ccache lib32-zlib lib32-ncurses lib32-readline ncurses5-compat-libs lib32-ncurses5-compat-libs ttf-dejavu lib32-gcc-libs flex bison  xml2 lzop pngcrush imagemagick lineageos-devel aosp-devel libxcrypt-compat
