WARNING: "setup_irq" [/home/misbah/driver_Hwtimer/omap_timer.ko] undefined!

Hi all,

I am compiling a driver code which is giving the compilation error for "setup_irq" function not defined. I am including all the header file for for its declaration. Other inbuilt drivers which are already there with the kernel source is also giving error if i compile seperatly.

I have no idea why it is not able to find the setup_irq function where in it has the extern declaration in the file /linux/irq.h

Insted if this function if i use request_irq to hook the interrupt it compiles but it does not gets the interrupt

can any one suggest me where am i going wrong :(

What could be the possible reason to such problem ...
