Problems compiling at91 driver for samutils-0.2.1

Question

Hello All!
I'm having problems compiling the usb driver for sam7 tools. I am receiving the following errors:

Thank you for the reply, I noticed that the post below (its for Ubuntu) shows the gcc version to be 4.0.3
[link]http://www.makingthings.com/documentati … -sam7utils[/link]
I poked around the Makefile in /usr/src/linux-2.6.39 and got rid of "-Wall" and "-Wno-implicit-function-declaration"
it compiled with the following warnings:
make[1]: Entering directory `/usr/src/linux-2.6.39-ARCH'
Building modules, stage 2.

LD [M] /home/bailey/Source/sam7utils-0.2.1/driver/at91.ko
make[1]: Leaving directory `/usr/src/linux-2.6.39-ARCH'
but when I tried to install, the output was
insmod: error inserting 'at91.ko': -1 Unknown symbol in module
Unfortunately, I tried grabbing the package from the AUR, but I ran into the same issues. Seems the only common factor in this process is gcc.
Thanks for the help
