Compile helloworldMakefile with linux2.6 driver

Compile helloworldMakefile-Linux general technology-Linux programming and kernel information by using the linux2.6 driver. The following is a detailed description. Taking hello world version 2.6 as an example, we will introduce how to write the linux2.6 driver.

Source program:

# Include
# Include
# Include

MODULE_LICENSE ("GPL"); // description

Static int hello_init (void ){
Printk (KERN_ALERT "Hello, world \ n ");
Return 0;
}
Static void hello_exit (void ){
Printk ("Goodbye, cruel world \ n ");
}

Module_init (hello_init );
Module_exit (hello_exit );

Compile a file (makefile). It is recommended that you do not paste it. If there is a format problem, manually click it. This is a simple form and some judgment statements are omitted.

Ifneq ($ (KERNELRELEASE ),)
Obj-m: = QD01.o
Else
KDIR =/lib/modules/$ (shell uname-r)/build
PWD: = $ (shell pwd)
Default:
$ (MAKE)-C $ (KDIR) M = $ (PWD) modules
Endif

After several days of painstaking search, we finally got it done! Yeah!
