HPUX DLKM: Error "symbol gio_mod_ops undefined"

[rahuljainbit]

Hi,
I am facing a weird problem. I am able to compile ,install my module but when i give config command, it returns me an error stating: "symbol gio_mod_ops undefined".
I am compiling on PA-RISC2.0 64 bit kernel using 11.11.
I have included all file :
#include
#include
#include
#include
#include
#include
#include
#include
#include

I have defined line "extern struct mod_operations gio_mod_ops;" which is returning error. At the time of linking, it is not able to find the symbol. Also, this symbol is not defined in any fo the files in /usr/conf/sys.

Please provide a solution to my problem.
Thanks in advance.
