[gentoo-user] Cannot compile ipw2100 against kernel 2.6.13

[gentoo-user] Cannot compile ipw2100 against kernel 2.6.13

[John Green]

Hi,

I have been using wireless on my Dell laptop successfully under kernel
2.6.12
and earlier, but I can't get it to build under kernel 2.6.13.  Specifically,
the ipw2100 package fails to compile against kernel 2.6.13.{,1,2}.  I
have looked in
bugzilla, but couldn't see anything relevant.  M`aybe I'm missing a
trick somewhere.

In detail, when

/usr/src/linux => /usr/src/linux-2.6.12.6

everything works OK.

But when

/usr/src/linux => /usr/src/linux-2.6.13.2

there are errors beginning like this.

------------------

BTW, I am totally confused about in-kernel versus out-of-kernel software
for Intel wireless
and about the hardware/driver nomenclature.  Here is the (possibly)
relevant part of
my kernel .config file.

----------------------

#

-----------------------

(I sometimes use a PCMCIA cable-ethernet card, but not at present.)

There is a comment that the ipw in-kernel driver may change in 2.6.14,
but I don't want to wait
for that if it turns out to be my error anyway.

Thanks,

John Green

hum, have you tried asking about on ipw2100.sourceforge.net?
There's an IRC channel on freenode and they also have their own bug
database you can search through. Maybe you will find something there?

if I remember correctly, the ipw2?00 ebuilds checks for kernel options
before emerging, so if it got to the compile phase it shouldn't be a
problem with your kernel setup. Or at least a known problem.

BTW, the current ~x86 version of the ipw2100 ebuild has a check for 
this, and if the file exists, it will prompt you to remove it and then 
fail the build.

You might try:

echo "net-wireless/ipw2100 ~x86" >>/etc/portage/package.keywords
emerge -Dv net-wireless/ipw2100

I'm using ipw2100-1.1.2-r3 with suspend2-sources-2.6.13-r4 without any 
significant problems.

Thanks for the tip. Their bug database did not help, so it was IRC or
nothing.
I'd been on IRC only once before, and that was two years ago... so this time
I made notes on how to do it. Anyway, someone on freenode/#ipw2100 thought
the problem might be with ieee80211. A detailed look at my log file for
rebuilding ieee80211
under 2.6.13.2 showed that the ebuild tried to delete kernel file
include/net/ieee80211.h,
but failed with insufficient privilege, even though emerge was running
as root. I deleted
the kernel header file by hand and the ebuild for ipw2100 then ran
successfully.
Kernel 2.6.12.6 does not contain the file include/net/ieee80211.h, so the
compilation error never happened with that kernel.

Unfortunately, wireless would still not work under 2.6.13.2, despite
many rebuilds
in different orders and many reboots. I guess I'll stick with kernel
2.6.12.6 for now.
If I ever do get wireless working under 2.6.13 or higher, I'll try to
add a note to the
Gentoo Wiki for ipw2100. (More learning and note-taking!)

I use a script to detect errors in ebuild log files because the logs are
usually too long to read.
The script clearly needs an extra clause to highlight the phrase
'insufficient privilege'.

Thanks for the tip, but it did not help.  I still get no communication
when running with 2.6.13.2.

I guess I'll wait for 2.6.14 and try again.
