Compiling program with ns_initparse() function C linux

I have installed BIND. I am using -lresolv as paramete while compiling in gcc. But it is giving error:

/usr/lib/gcc/i386-redhat-linux/4.3.0/../../../crt1.o:开发者_StackOverflow中文版 In function `_start':
(.text+0x18): undefined reference to `main'
/tmp/cck9LhAK.o: In function `resolvmx':

res.c:(.text+0xda): undefined reference to `__ns_parserr'
res.c:(.text+0x11c): undefined reference to `__ns_sprintrr'

You forgot to add main.o (or main.c) to your link line.
