Nvidia and kernel-2.6.29.1_rt4

Question

hey, which nvidia-rt-173xx driver works? I keep getting errors...
*** Unable to determine the target kernel version. ***
make: *** [select_makefile] Error 1
install: cannot stat `nvidia.ko': No such file or directory
I've tried 173.14.12 and 173.14.18
do I need kernel-firmware from testing??
I removed the kernel-firmware when I tried rt1
this was mentioned, thanx to fackamato...
Yeah it fails because it can't find the kernel sources/headers... I had to manually do sudo sh NVIDIA-driver.sh --with-kernel-source=/path/to/kernel26-rt/src/linux-2.6.29.1 .
185.19 works for me this way. I guess something should be changed in the PKGBUILD in order for this not to be needed...
one problem, can you explain this: "--with-kernel-source=/path/to/kernel26-rt/src/linux-2.6.29.1"
that fails with this command: sudo sh NVIDIA-Linux-x86-173.14.18-pkg1.run

Answer 1

thanx Ranguvar but this is the PKGBUILD I'm using that I got from AUR and edited for the latest kernel26rt.
pkgname=nvidia-rt-173xx
pkgver=173.14.18

  cd usr/src/nv/

  sed -i -e "s/KERNEL_VERSION='.*'/KERNEL_VERSION='2.6.29-rt'/" $startdir/*.install
Where am I going wrong?
