[openib-general] using VAPI and CMAPI in kernel module.

Tue Oct 5 05:46:31 PDT 2004

Hi,

I'm trying to compile a kernel module which use the VAPI and (maybe) the 
CMAPI. And when I compile a file with an inclusion of vapi.h I got this :

the file is simply :

#include <linux/module.h>
#include <linux/kernel.h>
#include <vapi.h>

int init_hello(void)
{
    printk(KERN_NOTICE "Hello, world\n");
    return 0;
}

void cleanup_hello(void)
{
    printk(KERN_ALERT "Goodbye, cruel world\n");
}

module_init(init_hello);
module_exit(cleanup_hello);

and the Makefile :

KDIR = /lib/modules/$(shell uname -r)/build/
EXTRA_CFLAGS 
:=-I/usr/src/linux-2.6.7/drivers/infiniband/hw/mellanox-hca/include/ -O2 
-Wall

obj-m += exemple01.o
default:
    $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

clean :
    rm -rf *~ *.o *.ko

If someone tried something like that befor could he send me some very 
simple examples?

I'm using the openIB stack on a 2.6.7 kernel.

Thanks...
