I've searched a bit on this forum, but I can't seem to find pointers or clues to my problem.
I'm trying to install the latest ATI linux drivers for Mandrake 10, and here's the message I get:
*** Trying to install a precompiled kernel module.
*** WARNING ***
Tailored kernel module for fglrx not present in your system.
You must go to /lib/modules/fglrx/build_mod subdir
and execute './make.sh' to build a fully customed kernel module.
Afterwards go to /lib/modules/fglrx and run './make_install.sh'
in order to install the module into your kernel's module repository.
(see readme.txt for more details.)

As of now you can still run your XServer in 2D, but hardware acclerated
OpenGL will not work and 2D graphics will lack performance.

failed.
*** Error: no kernel module build environment - please consult readme.
*** Warning ***
The QT based control panel application did not load in any version.

ATI display drivers successfully installed
please run 'fglrxconfig' now

Now, I try to run ... sh make.sh in the dir /lib/modules/fglrx/build_mod - and I get this error message:
ATI module generator V 2.0
==========================
initializing...
Error:
kernel includes at /usr/src/linux/include do not match current kernel.
they are versioned as ""
instead of "2.6.3-7mdk-p3-smp-64GB".
you might need to adjust your symlinks:
- /usr/include
- /usr/src/linux

Now, in /usr/src I have the fhe following link: linux -> linux-2.6.3-19mdk/
Also under /usr/src I have these directories:
drwxr-xr-x 2 root root 4096 Oct 18 23:26 ATI/
lrwxrwxrwx 1 root root 17 Oct 9 17:25 linux -> linux-2.6.3-19mdk/
drwxr-xr-x 19 root root 4096 Oct 9 17:25 linux-2.6.3-16mdk/
drwxr-xr-x 21 root root 4096 Oct 18 22:53 linux-2.6.3-19mdk/
drwxr-xr-x 7 root root 4096 Oct 5 15:05 RPM/

I'm really at a loss now; I don't know exactly how to get these drivers loaded.
I do know that my CPU has HyperThreading enabled; which is the reason why Mandrake loaded a bunch of kernels that come up as options on my lilo.conf file.
Lilo.conf is set to: default="linux"
and
image=/boot/vmlinuz
label="linux"
root=/dev/sda5
initrd=/boot/initrd.img
append="devfs=mount acpi=ht splash=silent"
vga=788
read-only

Hopefully all this information can give you an idea as to what it may be going on with my configuration that it won't allow me to install ATI drivers.

Thanks for your help and time reading this long message.

I remember I had that problem a long time ago and I installed my kernel-source and it solved all the problem. Hopefully it will work with your problem.

I do have kernel-sources loaded - that was my first step when I go this message.
I'm kind of giving up - I have yet to get any 3D drivers to work with any Linux distro

Thanks for your reply.

Ok, I think I found my problem...

2.6.3-7mdk-p3-smp-64GB is reported by uname -r - so this is my default linux image.
Since my computer has HyperThreading enabled, Mandrake configured about 5 different images for LILO, but it appears that 2.6.3-7mdk-p3-smp-64GB is my default image.
Now, 2.6.3-7mdk is the image I just selected and the one that I loaded kernel-sources for and the ATI drivers installed just fine.
I can't find any kernel-sources for 2.6.3-7mdk-p3-smp-64GB, so I'm assuming that's been my problem, but it also means that Linux is not taking advantage of HT feature on my computer.
Any of you know how to go about finding kernel-sources for 2.6.3-7mdk-p3-smp-64GB? I'm sure that if I find those sources and re-install ATI drivers I will have both 3D drivers and HT enabled on my Linux box.

Thanks.
