cannot compile compate-wirless snapshots

cannot compile compate-wirless snapshots

[Malte Gell]

Hello,

actually I can build the stable compat-wirless-2.6.30.ta.bz2 just fine.

But I get make errors, when I try to build the daily snapshot, see below. I 
use openSUSE on a 2.6.27 kernel.

Thanx, Malte

Hi,

what kernel are you using? It looks to me you are using 2.6.27, but the
2.6.27 mainline kernel does *not* contain the tracepoint infrastructure
and include/linux/tracepoint.h, like your kernel. Did you made some big
 modifications to your kernel or is it the default openSUSE kernel?

Does this file exists in your installation?
/lib/modules/`uname -r`/build/include/linux/tracepoint.h ?

Compat-wireless checks the kernel version and adds some compat code
based on the things the mainline kernel misses in this version, but this
is not working correctly with kernel, because it looks like it contains
some "bad" modifications.

2.6.27.29-0.1 from openSUSE 11.1

Yes ! The kernel tracepoint API is there in openSuSE11.1, but I still cannot 
compile compat-wireless-2.6

 Besides tracepoint thing, does ar9170us require 2.6.29? As said, tracepoint 
does exist in my kernel....

thanx
Malte

Yes, but, look:

cd /usr/src/linux

grep -i tracepoint .config

# CONFIG_TRACEPOINTS is not set

Do I need to set it to yes?

No. You should not manually edit any kernel config file (the
compat-wireless module should be built against a config matching your
running kernel, not a massaged version of it) and what is in
/usr/src/linux is irrelevant , because that is not your running
kernel.

The relevant config is probably /boot/config-`uname -r`, but, please
do *not* modify it.

I already wrote - your best bet is simply deleting all the 'error
redefintion' parts from net/compat-2.6.28.h, since your kernel tree is
somewhere between 2.6.27 and 2.6.28 . (and also delete some part of
net/compat-2.6.28.c when possible later linker error arises).

It should be in /proc/config.gz. (/boot/config-* is an Ubuntuism.)

No -- it is at least that way in Fedora and RHEL as well.

John pointed out Fedora & RHEL does /boot/config-*  . (and don't
provide /proc/config.gz). I don't know which distro does
/proc/config.gz Obviously neither Ubuntu nor Fedora/RHEL; maybe one of
Mandriva/Debian/Suse?

As a point of interest, /boot also contains the init ramdisk, the
kernel symbol map besides the kernel image (beside some
grub/boot-loader files), so it isn't too much to have another kernel
related file. For the purist, building the kernel to have
self-knowledge of its own config under /proc is a neat thing, but
OTOH, it uses kernel memory to provide what is very static unchanging
info under /proc, which is unwise.
