Some distributions even use headers which are derived from 2.4 kernels.

When this work is finished, it will be the right thing to do. But this is still way in the future - I would not expect this to work really well before the end of the year. -- [EMAIL PROTECTED] mailing list

As it turns out, I am using 2.6.20-r2 headers and they work for me.

Thanks for the explanation. As replied just now, my understand was
wrong.
Or have you been reading the stuff in /usr/src/linux/Documentation about
how you shouldn't put kernel sources in /usr/src/linux?
OOPS...

You don't. Really. The kernel headers which come with the source tarball are not a good choice for userspace. Don't do it, you don't have a compelling reason. And if you have a very good reason for the in-kernel headers (like app X needs them), it is a bug. -- [EMAIL PROTECTED] mailing list -- [EMAIL PROTECTED] mailing list

Why do you want to do that?
The kernel and kernel headers are completely different things and have
nothing to do with each other, except that the headers came out of a
kernel tarball once.
The kernel source is the kernel source, it's a free-standing compilable
block of C.
The kernel-headers are there so the *user*apps*and*libs* know what
definitions of data structures to use. In very broad terms, someone
takes the .h files out of a kernel release that are known to be stable
and work well and make them available to user-space compilation. Gentoo
puts them in /usr/include/{asm,linux}. Leave them there.
Or have you been reading the stuff in /usr/src/linux/Documentation about
how you shouldn't put kernel sources in /usr/src/linux?

[gentoo-user] Touble with linux-headers
Hello, I would like to install my own version of the kernel (2.6.18.3) which i have compiled and installed. This is working fine. But when I try to do 'emerge system', portage is trying to emerge linux-headers also. How can I prevent it ? Also , when using a homebrew source, how do I install the linux-headers in /usr/include ? just copy the directory from the kerenl source, or symlink it ? To prevent portage from trying to install its own version I have added the homebrew-sources-2.6.99.ebuild to the /usr/local/portage. When I do 'emerge homebrew-sources' I get the following. I am confused as to what to do next. In the homebrew-sources ebuild, the function are just dummy (returnning true) any pointers ? thanks sathish - Emerging (1 of 1) sys-kernel/homebrew-sources-2.6.99 to / * checking ebuild checksums ;-) ...
