This is a kernel issue and should be fixed in kernel unless we want
to do something in <sys/sysctl.h>.

You should not include kernel headers from userspace.

Old story I know but I dont think binutils would use kernel headers if it
doesnt need it.

<sys/sysctl.h> includes <linux/sysctl.h>. That is what I meant by "do
something in <sys/sysctl.h>."

I know. and <linux/sysctl.h> is a kernel header libc shouldn't include.
So you want to do something to <sys/sysctl.h>, namely get rid of it's
depency on kernel headers.

Wouldn't this result in glibc-kernel inconsistency in headers?

How so?  If the sysctl values change you're screwed anyway.

Heh that was what I mean like what if glibc header and kernel header differs a
lot. Its bringing more harm than goodness but including linux/sysctl.h in
sys/sysctl.h makes two header synchronised.

Wondering what glibc guys think to solve this ? Ulrich Drepper or some other
glibc hacker make a comment please?

1. 2.5.69 - Nothing gets installed in /lib/modules/2.5.69/kernel

Hello,

I downloaded linux kernel 2.5.68 tarball, move 2.5.68 to 2.5.69,
patched it with patch-2.5.69 and then the latest cset. And after a
little struggle, got module-init-tools also installed. The "make
install" runs smoothly but no modules are installed under
/lib/modules/2.5.69/kernel.

I checked if modules are getting built. So I checked under fs/smbfs to
see if there were any .o files as I had selected smbfs to be built as
a module. But no .o files there.

Any indicators as to be what could be the problem?

I am running all this on Mandrake 9.1.

TIA,

Siddhartha
