Custom kernel + old headers ?

merchtemeagle · 11-06-2006, 06:23 PM

I'm trying to get my Slackware running as is described on http://users.piuha.net/martti/comp/s...slackware.html. The purpose is to have a truly minimal Slackware installation and to use pkgsrc for installing all other software.

At one point, the author shows a list of packages that should not be removed. None of the kernel-related packages, not even the kernel-headers are in that list. He then runs following code before building a custom kernel.

Code:

# cd /usr/include
# rm -rf asm* linux
# ln -s /usr/src/linux/include/linux
# ln -s /usr/src/linux/include/asm-i386
# ln -s asm-i386 asm
# ln -s /usr/src/linux/include/asm-generic

However, I've read in another thread that the kernel headers should be the same ones against which glibc was compiled. Is this a flaw in this HOWTO or am I missing something?

The kernel supplies it's own headers. The pkg kernel-headers is used for compiling other software and shouldn't be changed.

Head over to amigolinux.org for your choice of a few hundred programs for the system you are building. There are binary packages and sources also. Try the PkgBuild packaging system:

The 2.6.18.1 kernel I downloaded has a headers_install make target. I don't understand why this is necessary if only the headers glibc was compiled against should be in /usr/include.

You should definitely not run the commands that you posted in that code block!

There is enough information present in this Wiki as well as on the Slackware CD's that tell you what must be in /usr/include as part of the kernel-headers package (linux,asm and asm-386) and why that should not be symlinks to parts of the linux kernel source in /usr/src/linux. That part of the HOWTO you were reading is bad. The thread you linked to has the right info.

I started suspecting something like that. Thanks for the confirmation.
