Basic NIOS II interrupt.

I am now getting

warning: alt_legacy_irq.h: No such file or directory

--- Quote End ---

Ok....

I included

# include "priv/alt_legacy_irq.h"

Now I get warning.....

"passing argument 3 of 'alt_irq_register' from incompatible pointer type"

Prototype for alt_irq_resgister in priv/alt_legacy_irq.h is

extern int alt_irq_register (alt_u32 id,

void* context,

alt_isr_func handler);

As I said my file calls

alt_irq_register(CODEC_SIMPLE_MASTER_2_0_IRQ_INTERRUPT_CONTROLLER_ID, NULL, codec_isr);

codec_isr is handler and is defined as

static void codec_isr(void * context, alt_u32 id)

{

....
