编译 zsh

编译 zsh

0. 安装依赖 ncurses：

   sudo yum install ncurses-devel
   

1. 在 zsh.sourceforge.io 下载源码

2. 编译：

   ./configure --prefix=$HOME/.local
   make -j$(nproc)
   make install  # 如果安装到系统目录则要使用 sudo
   

Troubleshooting

No terminal handling library was found on your system

configure: error: in `/usr/local/src/zsh-5.9':
configure: error: "No terminal handling library was found on your system.
This is probably a library called 'curses' or 'ncurses'.  You may
need to install a package called 'curses-devel' or 'ncurses-devel' on your
system."
See `config.log' for more details

需要编译 ncurses 库，并将库安装路径添加到 LDFLAGS 环境变量：

export LDFLAGS="-L$HOME/.local/lib $LDFLAGS"

conflicting types for ‘boolcodes’

这是我在 CentOS 7 服务器上遇到的问题，这个问题我没能解决。后来想出了一个 workaround：建立一个本地的 CentOS 7 虚拟机，在虚拟机上编译并安装 zsh，然后将安装目录上传到服务器即可。
