glibc and kernel update

glibc and kernel update

[Rik van Riel]

Hi,

I still haven't resolved the problems between glibc, the
2.1 kernel series and pppd :(

Now I got a new idea: Since most of the kernel interfaces
go through glibc, does this mean that I have to get the
glibc source and recompile the whole thing in order to get
working ppp with a 2.1 kernel?

Just what problem are you having?

I just got 2.3.5 to compile with glibc, but I haven't had a chance to
test it yet..

Just tested it on 2.0 but compiled with 2.1.101 headers, and glibc.
I don't see any problems.  Explain your problem or start writing code :)

Pppd dies with "This kernel doesn't support PPP", while it
most certainly _does_. I traced it back to a socket operation
which isn't exported properly through glibc...

It compiles perfectly. It just doesn't run ;(

I just did a second test.
pppd-2.3.5 with glibc-2.0.6 on kernel-2.1.101 (with a few patches)
pppd works here.

The only thing I can imagine is do your /usr/include/linux & /usr/include/asm
point to ``safe'' kernel headers or the real thing.  Mine point to the real thing.

The glibc I have is compiled with a 2.0 kernel. I can
recompile pppd-2.3.5 as much as I like, but it refuses
to work with 2.1 kernels...

It says something like: "This kernel doesn't support ppp",
while that exact same kernel works perfectly with libc5
and the same pppd version :(
