Hi,

static int __init hello_init(void)
{
? ? ? ?printk(KERN_WARNING "Hello world\n");
? ? ? ?foo(); //defined in anther file

I removed the foo(); call

[root at localhost #] cat Makefile
obj-m += hello_multi.o
hello_multi-objs := helper.o

I removed the "hello_multi-objs := helper.o" line

complied the module, changed all printk's to KERN_INFO and it shows up in dmesg

I think the problem is with the "hello_multi-objs := helper.o" line.
There is something wrong with it.
