compat-wireless doesn't compile against 2.6.32 on Ubuntu beta

[Andrey Semyonov]

I get this when trying to compile current drivers:


/usr/local/src/compat-wireless-2010-04-14# make
make -C /lib/modules/2.6.32-19-generic/build
M=/usr/local/src/compat-wireless-2010-04-14 modules

make: *** [modules] Ошибка 2

The driver selected is b43. System is Ubuntu 10.04 beta2 (currently
available for testing).

I apologize if this is a duplicate, yesterday's attempt to send this
report haven't cause any mailing list notification nor this report
appeared in ML archives.

I confirm the problem.  Basically, the bleeding edge compat-wireless is
useless now.  Perhaps we need a check to to prevent broken tarballs from
being uploaded.  It's better than force users to search for the last
working tarball.

compat-wireless-2.6.34-rc4 should be OK for Linux 2.6.27 and newer,
although it lacks some fixes needed for older kernels.  It also lacks
the experimental wireless code that is not scheduled for Linux 2.6.34.

Right, I've noted in other threads what needs backport:

22bedad3ce112d5ca1eaf043d4990fa2ed698c87 net: convert multicast list
to list_head
2f787b0b76bf5de2eaa3ca3a29d89123ae03c856 mac80211: Ensure initializing
private mc_list in prepare_multicast().

These just need to be reverted through an ifdef, just havent' had time
to do it yet.

Indeed, I once suggested to do this on johill's box but he had little
space, I now moved the tarball building to orbit and we have plenty of
space there so we could do the automatic compile checks against all
stable kernels we support prior to uploading. Just need to get that
done.
