Makefile error?

[pitorito]

Hi guys
I was trying to install my Genis Webcam, so I downloaded the drivers from http://mxhaard.free.fr/.
I entered with root user and I did all the steps. When I have to execute the MAKE file appears this error:


Building SPCA5XX driver for 2.5/2.6 kernel.
Remember: you must have read/write access to your kernel source tree.
make -C /lib/modules/`uname -r`/build SUBDIRS=/usr/local/src/spca5xx-v4l1goodbye CC=cc modules
make[1]: se ingresa al directorio `/usr/src/linux-headers-2.6.32-22-generic'
scripts/Makefile.build:49: *** CFLAGS was changed in "/usr/local/src/spca5xx-v4l1goodbye/Makefile". Fix it to use EXTRA_CFLAGS. Alto.

make[1]: se sale del directorio `/usr/src/linux-headers-2.6.32-22-generic'

:(

I don't know what to do.
