Summary:                    madwifi-cvs fails to build under 2.6.19.1 kernel
Description: 
I'm successfully running a 2.6.18.5 kernel with madwifi-cvs installed.

I've just built a 2.6.19.1 kernel, rebooted, and tried to rebuild the
madwifi-cvs module, but it fails. I've tried 'lin kernel-headers-2.6'
under the new kernel, but it makes no difference. The madwifi-cvs build
fails with (the full compile log is attached)

/usr/src/madwifi/ath_hal/ah_osdep.c:44:26: linux/config.h: No such file or
directory

Is this a kernel config problem; a new module that needs to be installed
first, or a problem with madwifi-cvs under the new kernel ?

drop back to 2.6.18.x and wait for an updated madwifi module, it's
something they need to fix in their code.

you can of course attempt to sedit 's/linux\/config.h/linux\/autoconf.h/'
the madwifi code and see if that fixes it.

Yes, I already dropped back to 2.6.18.5 otherwise I would have to
move the machine downstairs to use the wired connection to the hub.

Posted basically the same report on the madwifi-users mailing list
and got the following reply:
http://sourceforge.net/mailarchive/message.php?msg_id=37669518 or
http://article.gmane.org/gmane.linux.drivers.madwifi.user/11926

So if they switched from cvs to svn a year ago, what has the madwifi-cvs
module been downloading all of this time? A failsafe cached version?
[That could explain why it's way out of date in /var/spool/lunar]

Second, they say they've fixed some 2.6.19 related problems, so it
looks like the madwifi-cvs module needs to be updated/replaced. I'm
just not sure that I have the expertise to do this myself, but I'll
see how far I get this evening. Is there anything special I need to
do for a kernel module like this as opposed to a user-space application?
e.g. when I tried wpa_supplicant there was all sorts of stuff about
copying files into the kernel source tree etc.

I just added the madwifi-svn module to the moonbase. It needs testing
though. I can confirm that it compiles but I cannot verify that it
actually works.

Also, I think you won't need to compile it twice anymore whenever you
update your kernel (major annoyance I can imagine).

If you want to give it a shot right away download the module from

http://foo-projects.org/~moe/madwifi-svn.tar.bz2

I installed Moe's "zlocal/madwifi" module, but the last stable tarball
for 0.9.2.1 of 2006-12-07 shows the same error under a 2.6.19.1 kernel.

However, Moe's new "zbeta/madwifi-svn" module works like a charm. It
downloaded
and built without problems, and didn't need a rebuild after reboot
either.

Now that I'm signed up on the madwifi-users mailing list, I shall monitor
it
for the next tarball release, and update "zlocal/madwifi" to use it. If
it
works, I shall submit it and steal Moe's glory :-)
