这是因为lua编译依赖readline库，readline库依赖ncurses库，但没有指定，就会出现“未定义的符合引用”错误。

解决方案是修改${LUA_DIR}/src/Makefile中linux编译target=linux，在SYSLIBS变量中追加‘-lncurses’选项即可。如下：

105 linux:106         $(MAKE) $(ALL) SYSCFLAGS="-DLUA_USE_LINUX" SYSLIBS="-Wl,-E -ldl -lreadline -lncurses"

此时重新执行：

[root@~/software/lua-5.2.3]# make linux installcd src && make linuxmake[1]: Entering directory `/root/software/lua-5.2.3/src'make all SYSCFLAGS="-DLUA_USE_LINUX" SYSLIBS="-Wl,-E -ldl -lreadline -lncurses"make[2]: Entering directory `/root/software/lua-5.2.3/src'make[2]: Nothing to be done for `all'.make[2]: Leaving directory `/root/software/lua-5.2.3/src'make[1]: Leaving directory `/root/software/lua-5.2.3/src'cd src && mkdir -p /usr/local/bin /usr/local/include /usr/local/lib /usr/local/man/man1 /usr/local/share/lua/5.2 /usr/local/lib/lua/5.2cd src && install -p -m 0755 lua luac /usr/local/bincd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp /usr/local/includecd src && install -p -m 0644 liblua.a /usr/local/libcd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1

至此，lua-5.2.3安装成功：
