Do you have a better idea of how can I fix that? I'll really appreciate
it.
Yeah, try to compat-wireless-2.6.36-rc2 ...

Nope... the same error...

That didn't help. I hope you can give me another idea.
Thanks.
So...? What should I do?
Sorry, I have not have had time to test compile against 2.6.35, but
when I do I will let you know.

Hi,

I was able to reproduce the problem. In the kernel configuration
CONFIG_WIRELESS_EXT=n and CONFIG_CFG80211_WEXT=y are set.
compat-wireless uses the old wireless_handlers attribute for the wext
handlers interface, but this is only activated if CONFIG_WIRELESS_EXT=y
is set.
We can not use the new interface through struct wiphy that cfg80211_wext
normally uses. The struct is shipped by compat-wireless and changed
ofter with different kernel versions, so the pointers do not point to
the correct position when using two different versions of this strcut.
compat-wireless should *always* deactivates CONFIG_CFG80211_WEXT if
CONFIG_WIRELESS_EXT is not set. I got our compat_autoconf.h to overwirte
the kernels autoconf.h by add it to LINUXINCLUDE, but I have not found a
way how to disable CONFIG_WIRELESS_EXT in the makefile if it was set in
the kernel because config.mk is pared before the kernel configuration is
parsed. An other way would be to rename CONFIG_WIRELESS_EXT to something
else in compat-wireless to prevent the kernel from overwriting this value.

There will be no way to support cfg80211_wext without a kernel
configured with CONFIG_CFG80211_WEXT=y.

So, as far as I got it, it won't work until a patch is submitted in compat-wireless? I'll try to build my kernel using the config you suggested and I'll tell you how does it goes.
Thanks.
