Bug 451084 – x11-drivers/nvidia-drivers: check in pkg_pretend whether driver is compiled against supported kernel version

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description walt 2013-01-09 19:26:55 UTC]

nvidia-drivers-304.64 works nicely with kernel 3.6.11, but the kernel module won't compile yet with 3.7.x

Reproducible: Always




No doubt upstream will fix this before long, but meanwhile it would be nice to add a warning/dependency to the ebuild.

We have no idea if it will or won't work against a newer kernel before the code is written. We'd spend forever updating einfo messages.

Better suggestion xarthisius?

@walt 
with arch ~amd64 
x11-drivers/nvidia-drivers-313.18
compiles nicely against linux-3.7.6

But you need to make a link to new uapi directory:
ln -s /usr/src/linux/include/generated/uapi/linux/version.h /usr/src/linux/include/linux/version.h

pay attention:

new nvidia-drivers give compatibility problems with some old cards.
so is very important to know if old drivers may work with kernel 37.* or not.

Thanks Ulenrich -- this worked for me!

There's a message in pkg_pretend now.
