problems compiling module

[cee124]

Hello, i am new to linux, C, and this forum, but i was hoping to get some help. Im trying to learn how to create kernel modules, its for a school project as well. I got the simple hello world module working, so i tried to make one that took parameters from terminal. It looks like this

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

static char name[] = "name";
module_param(name, char, 0);
MODULE_PARM_DESC(name, "The name of the person being greeted);

int init_module(void)
{

printk(KERN_INFO "Hello %s\n", name);
return 0;
}

void cleanup_module(void)
{
printk(KERN_INFO "Goodbye %s\n", name);
}

the Makefile looks like this

bj -m += hello3.o

all:
make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean

when i run the make command i get no errors, but when i ls the dir afterwards i only see modules.order and Module.symvers. This is my problem, where is the .ko file? What did i do wrong?

I can see three problems here. In the Make file there should be obj-m += hello3.o. In hello3.c module_param should be declared like this:

static char *name = "name";

module_param(name, charp, 0);

And in the MODULE_PARM_DESC() there should be double quote the end
