Compiling and Loading Kernel Modules in FC5

zeeshanhayat · 12-18-2006, 11:47 PM

Well this is my first attempt at creating a kernel module. I went on like that.

#include <linux/module.h> /* Needed by all modules */
#include <linux/kernel.h> /* Needed for KERN_INFO */

int init_module(void)
{
printk(KERN_INFO "The Usual Hello world Program.\n");
return 0;
}

void cleanup_module(void)
{
printk(KERN_INFO "Unloading.\n");
}

The Make File..

obj-m += hello-1.o

all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

Now when i run make i get the problem,

make: *** No targets specified and no makefile found. Stop.

when i run "make MakeFile" i get the following message
make: Nothing to be done for `MakeFile'.

I am running Fedora Core 5.
Any Ideas..

This error occur when the name of your makefile isn't Makefile.. and the second error is because you specify a Makefile to make with this command:"make --makefile=you_makefile" see make --help

But my Make file is named MakeFile

mv MakeFile Makefile
this should works

these is a difference between MakeFile and Makefile.. linux differ Capital letter...
