Hiya I am trying to build a Kernel driver for a WinTV nova card but am getting this output from thr build process !

Linux localhost.localdomain 2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:34:46 EST 2006 x86_64 x86_64 x86_64 GNU/Linux

The kernel devlop package is installed so I am at a loss about this I have the same error from madwifi package as well

Many Thanks

Copy your kernel .config into the kernel source and run make

ok I copied the kernel config from the /boot dir to /usr/src/kernels/2.6.18-1.2849.fc6-x86_64 and reran 'make'

make -C /lib/modules/2.6.18-1.2849.fc6/build SUBDIRS=/home/mythTV/Desktop/v4l-dvb-20060717.tar.gz_FILES/v4l modules

still some problems what is this config.h file for ?

It contains more or less the same info as the .config file you copied from /boot.
Your new error message makes no sense to me, it looks like whatever you're trying to compile expects the kernel's config.h file to be installed in /usr/include/linux, which is bonkers. Which WinTV nova card have you got? What chipset does it have, or. to put that another way, what does lspci say about it?

Create an empty config.h file in <kernel-source-dir>/include/linux. Just

touch /usr/src/kernels/2.6.18-1.2849.fc6-x86_64/include/linux/config.h

Then retry your make.
