I'm currently trying to write my first linux driver. I'd like to write it as a module.
To begin with something, I wrote a small skeleton with some entry points (open, close, ioctl, etc) and also included init_module() and cleanup_module(). I included calls to printk() in these functions for debugging purpose. I addition, I included the following version definition (taken from another driver):
#include <linux/version.h> char kernel_version[] = UTS_RELEASE;
I then compiled this module as follows:
gcc -Wall -c pl_loopback.c -o pl_loopback.o -D__LINUX__ -DLINUX -D__KERNEL__
Now, if I try to load the module with "insmod pl_loopback", I obtain the following error message:
printk undefined Failed to load module! The symbols from kernel 1.2.13 don't match 1.2.13
So, I presume that I forgot something... Any idea....?
Thanks
