Question: Hardware Interface I/O Access

Forum: Device Drivers
Keywords: I/O

From: Terry Moore <tmoore@solbrn.dseg.ti.com> 

I need to write a driver using inb() and outb().
I am struggling with compiling a simple test program
to test these fuctions. 
(1.) If I use gcc -o -DMODULE -D__KERNEL__ -c myfile.c
     I do not understand how to use the resulting file
     created -DMODULE.
(2.) If I use gcc -o tst tst.c the following fail appears. 		
     undefined reference to __inbc
     undefeined reference to __inb

What I expected was a executable program to run from the command line.

Thanks Terry M. tmoore@solbrn.dseg.ti.com
