sir ,

   i m new to this driver programming . i m on 2nd chapter of
 "linux device drivers " .

 i tried to do the following :


*********************************************** TEST.C **********


 # define MODULE
 # define __KERNEL__

 # define value 50
 # define EXPORT_SYMTAB

 
 MODULE_LISENCE("GPL");
 
 EXPORT_SYMBOL(value);


 int init_module (void)
 {
 }

 void cleanup_module(void)
 {
 }


*************************************************

i cant compile this with

 gcc -c test.c

MODULE_LISENCE("GPL");
Shouldn't this be MODULE_LICENSE?
 
 EXPORT_SYMBOL(value);
Have you previously declared "value" ?

It would be useful if you gave more specific information than "there is some errors".  What did the compiler say?
