I'm trying to get the madwifi drivers installed for my ath9k wifi card.
When I go to "make" the drivers, I get this error:

make
Code:
./kernelversion.c:14:34: fatal error: generated/utsrelease.h: No such file or directory
compilation terminated.
Makefile.inc:81: *** Cannot detect kernel version - please check compiler and KERNELPATH.  Stop.
Some useful stuff I can think of:

uname -r
Code:
2.6.38-11-generic-pae
apt-get install linux-headers-generic-pae
Code:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
linux-headers-generic-pae is already the newest version.
I'm not sure why make won't work. I'd really like to compile this patch. Any help would be greatly appreciated
