kernel headers?


Hi everyone,
I am building a lfs machine using instructions in the book version 6.0.
One thing that puzzles me is that you have two kinds of "kernel headers": one from the linux-libc-headers package (I used linux-libc-headers-2.6.8.1/include/linux and linux-libc-headers-2.6.8.1/include/asm-i386), and another extracted from the linux kernel archive (I used linux-2.6.8.1/include/{asm-i386 | asm-generic | linux} folders).

What are the differences between these headers? Why is it necessary to use both sets? I have a look inside the folders and many file names (*.h) are the same.

Could someone with the knowledge give me some leads? I'd be very grateful.

Thanks a lot,
Krappy

The linux-libc headers are the ones that your glibc are built against. These should not be changed unless you want to rebuild glibc. The headers that come with the kernel source are used to build modules and the like, and as such, they must change to match your kernel.

PS: this isn't just with LFS, all distros are like this
