Lua编译错误小结

编译Lua代码， 出现以下错误

/usr/lib/libreadline.so: undefined reference to `PC'
/usr/lib/libreadline.so: undefined reference to `tgetflag'
/usr/lib/ibreadline.so: undefined reference to `tgetent'
/usr/lib/libreadline.so: undefined reference to `UP'
/usr/lib/libreadline.so: undefined reference to `tputs'
/usr/lib/libreadline.so: undefined reference to `tgoto'
/usr/lib/libreadline.so: undefined reference to `tgetnum'
/usr/lib/libreadline.so: undefined reference to `BC'
/usr/lib/libreadline.so: undefined reference t

原因在于lua编译依赖libreadline, 如果libreadline编译没有连接ncurses库(-lncurses), 编译Lua就会遇到这个错误， 解决办法是重装readline, debian下面 apt-get install libreadline

(如果是自己下载readline编译， 要注意加上-lncurses进行编译， 不然依然会有上面的问题）
