[gentoo-user] Can't find b43 in kernel config

[gentoo-user] Can't find b43 in kernel config

[Grant]

I've satisfied these requirements:

Depends on: NETDEVICES [=y] && WLAN [=y] && SSB_POSSIBLE [=y] &&
MAC80211 [=n] && HAS_DMA [=y]

but I don't see the option here:

Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Wireless LAN (WLAN [=y])

Does anyone know how to make it appear?

What is 'b43'?

When I have that problem I typically start with

cat /usr/src/.config | grep b43

which returns nothing implying to me that b43 doesn't exist at all.

If you do a make menuconfig and search for b43, lots of stuff comes up
including "B43".

Mark this isn't a good test. It only says that your config doesn't 
contain references to b43.

If you do "make menuconfig" and then search for b43 (type slash to reach 
the search functionality) many entries will show up: I count 23 hits in 
2.6.39-gentoo-r1 kernel.

Grant: you say that the requirements are satisfied, yet I see "MAC80211 
[=n]", could be it? Same way as above to see where the option you lack 
can be activated

Thanks Francesco. I didn't know that the config would eliminate
options. My experience in the past had been that it would be in the
config but commented out and saying 'not set'.

Good to know this if I have a problem like this again in the future.

Cheers,
Mark

Ah, thank you Francesco.  I was reading that to mean that it was
required for MAC80211 to *not* be selected.  Now I've got it.

You'll invariably also need the appropriate firmware too.  You'll need to 
emerge net-wireless/b43-fwcutter and have a look at:

http://linuxwireless.org/en/users/Drivers/b43

PS. Ignore the notes for b43legacy and bcm43xx drivers.

Apparently, though unproven, at 19:10 on Thursday 09 June 2011, Grant did 
opine thusly:

It looks like you did not satisfy MAC80211.

Where did copy that Depends from? When I use 'h' in menuconfig mine shows up 
as [=m]

It's very close to the middle item in the list (so you know where it goes once 
it's visible)

Yeah, I misunderstood the depends line.

I didn't know about that 'h' command.  I got the Depends from
2.6.38-hardened-r6 by using '/'.
