[SOLVED]Can't emerge Legacy nvidia-drivers

[daschapa]

Excuse my bad english.
I have a nVidia Riva TNT2/M64. Very old for new drivers, so i need legacy ones.
I've updated to kernel 2.6.23 today and when trying to rebuild my drivers i found that gentoo has changed the some things.
I was using nvidia-drivers-1.0.7185, but now, the only one that looks like being a legacy one is nvidia-drivers-71.86.02 and 71.86.04. All packages prior to version 100.x.x are masked (with package mask), and I had to unmask one.
When emerging, i had the next error

Code: Select all

...
        echo;                                                           \
        echo "  ERROR: Kernel configuration is invalid.";               \
        echo "         include/linux/autoconf.h or include/config/auto.conf are missing.";      \
        echo "         Run 'make oldconfig && make prepare' on kernel src to fix it.";  \
        echo;                                                           \
        /bin/false)

I haven't a clue about what happened. Anyone can help me?

I got the same error message 2.6.24 kernel and 100.14.23 drivers

Try to use genkernel and generate good kernel.

I have found the problem.
1- I have forgot to enable AGP in kernel

Code: Select all

  Device Drivers  --->
    Character Devices  --->
      <*>  /dev/agpgart (AGP Support)

2- As I'm using a legacy drivers, I had masked non-legacy drivers (>=x11-drivers/nvidia-legacy-1.0.8500) in /etc/portage/package.mask. With the new version number, all packages are considered above 1.0.8500, and this must be reformulated to >=x11-drivers/nvidia-drivers-85.00.00.

I hope anyone with the same problem find this helpful.
Thanx guys for your time.
