Oreilly's linux device driver example code...


I have Oreilly's "Linux Device Driver" 2nd and 3rd version example codes.
But I cannot compile both of them successfully.
(They seems just enter their directory and make...)
Could anyone tell me how to make it?

thanks!

It would help if you paste the error messages you're getting. Make sure you have GCC and your kernel headers, and you should be all set though.
