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

解决方式是改动${LUA_DIR}/src/Makefile中linux编译target=linux。在SYSLIBS变量中追加‘-lncurses’选项就可以。例如以下：

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

此时又一次运行：

[root@~/software/lua-5.2.3]# make linux install
cd src && make linux
make[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/5.2
cd src && install -p -m 0755 lua luac /usr/local/bin
cd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp /usr/local/include
cd src && install -p -m 0644 liblua.a /usr/local/lib
cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1

至此，lua-5.2.3成功安装：

[root@~/software/lua-5.2.3/src]# /usr/local/bin/lua -v
