[etherlab-users] problems making etherlab (+ other issues)

[Richard Hacker (MSc Eng)]

Hello Dusty

As I read from your mail, the output of the make program states that there is 
a problem in the file kernel-cflags.c

If you had attached this file to your mail, I might have been able to help you 
by now.

Maybe you also want to tell me which kernel version you are using, as well as 
describing your hardware platform (I see you are compiling an SMP kernel).
