You need to define the __KERNEL__ and MODULE symbols

#define __KERNEL__
#define MODULE

hello.c Source:

#include "/home/mzhu/linux/include/linux/config.h" 
/*retrieve the CONFIG_* macros */
#if defined(CONFIG_MODVERSIONS) && !defined(MODVERSIONS)
#define MODVERSIONS  /* force it on */
#endif

#ifdef MODVERSIONS
#include "/home/mzhu/linux/include/linux/modversions.h"
#endif

#include "/home/mzhu/linux/include/linux/module.h"

int init_module(void)  { printk("<1>Hello, world\n");  return 0; }
void cleanup_module(void) { printk("<1>Goodbye cruel world\n"); }

Output:

#>gcc -D_KERNEL_ -DMODULE -c hello.c

[This builds the hello.o file. ]

#>insmod hello.o

hello.o : unresolved symbol printk
