Hi,
    I'm trying to compile kernel 2.4.1 on RedHat 6.2 (zoot). After the make xconfig and make dep when I give make bzlilo I get the following error message

gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o 
scripts/split-include
scripts/split-include.c
In file included from /usr/include/errno.h:36,
                 from scripts/split-include.c:26:
/usr/include/bits/errno.h:25: linux/errno.h: No such file or directory
make: *** [scripts/split-include] Error 1

What should I do?
Yours ,

Make sure you have the following symlinks in your /usr/include
directory, assuming you're on an x86 machine:

asm -> /usr/src/linux/include/asm-i386/
linux -> /usr/src/linux/include/linux/

If you're using a different archetecture, check the
/usr/src/linux/include/ directory and make the link with that directory.

Note! You only have to have those symlinks on broken systems such
as Redhat.

Sane systems such as Debian have a copy of the kernel header files
that the C library was compiled against in /usr/include/{linux,asm}
instead of symlinks to the kernel source. Do not play the symlink
trick on those systems.

Before this turns into a flamewar: this has been discussed 20 or
so times before, and both Linus and the glibc developers agree
that you a distribution should do the latter. The headers you use
to compile userland binaries should be the same as the C library
was compiled against.

If you need to compile a standalone module use -I/usr/src/linux/include

This is silly, Red Hat works fine for a great many people.

He probably removed the original kernel-devel package,
which contained the links above, so they would have to
be remade.

I'm glad you admit that Red Hat is every bit as sane as
debian, since the current shipping version does indeed
have the sort of /usr/include/linux hierarchy you have just
described.

Linking them to /usr/src and thus people linking them to current kernel sources
while basically harmless is indeed not the preferred approach. So he's right
that older RH should have put the headers for the kernel that match glibc into
/usr/include directly

< 7.0. 

On RH 6.x you should have a set of 2.2 header includes at /usr/src/linux as
required by the dependancies RPM uses.  (kernel-headers package).

7.0 or higher keeps the glibc includes out of /usr/src

I stand corrected. Thanks.

Wow, I had no idea.  I was following advice I received a long time ago
from a mailing list.  If I remove those symlinks how do I go about
compiling the kernel without receiving the same errors as Srinath?

Thanks for the correction,

Note that he said distributions such as RedHat (pre 7.0 .. I think 7.0
does it correctly). On other distros those headers are/should be
included with the glibc devel stuff.

You could probably copy those dirs into place on the broken distros
without problems.

I've been following this advice for some time, but doing so tripped me up.
My system is RH 6.2, but with kernel 2.4 (and latest modutils etc). I
kept my kernel headers at 2.2.14, i.e. those supplied with the 6.2
kernel-headers RPM.

This breaks XFree 86 4, however, which checks the kernel version you are
*running* and then expects the headers for that kernel to be available. To
build X I had to move the symlink to point at some 2.4 headers so X could
find (IIRC) input.h, and others. 

So what's at fault here? X for looking at the current kernel, me for not
telling X not to do that, or me again for not recompiling glibc and using
the new headers 'legally'?

Chris.
