1、报之类的错误

/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'

解决：

由于lua编译依赖readline库，而其依赖ncurses库，但没有指定，所以出现“未定义的符合引用”错误。需要修改${LUA_DIR}/src/Makefile中linux编译target，在SYSLIBS变量中追加‘-lncurses’选项即可。修改后，如下：

linux:

$(MAKE) $(ALL) SYSCFLAGS="-DLUA_USE_LINUX" SYSLIBS="-Wl,-E -ldl -lreadline -lncurses"

2、报cannot
find -lncurses

解决：

说明缺少libreadline-dev依赖包

centos: yum install readline-devel

debian: apt-get install libreadline-dev.
