Since 2012-12-04 building the ath9k module from compat-wireless fails when these build options are enabled.

export CONFIG_ATH9K_DEBUGFS=y
export CONFIG_ATH_DEBUG=y

This is the error message from a failed build.

That did not work for me with compat-wireless-2012-12-18-p.tar.bz2. 
It did not even build the ath9k module.

Comment 3 Sujith 2012-12-25 14:55:48 UTC

For compat-drivers, you can just uncomment this line in config.mk:
# export CONFIG_MAC80211_DEBUGFS=y

It did not build the ath9k module that time either.
Maybe it is a problem with that compat-drivers release?
I will try a older one to see if it works there.

Uncommenting export CONFIG_MAC80211_DEBUGFS=y works with compat-wireless-2012-12-17-p.tar.bz2.
It seems that the ath9k module is broken in compat-wireless-2012-12-18-p.tar.bz2, it does not build even with the default options.

Comment 6 Sujith 2012-12-26 02:07:01 UTC

Yes, I see it too - recent versions of compat-drivers appear to be broken.

Comment 7 Sujith 2013-06-03 02:34:10 UTC

The releases from the new "backports" project doesn't have this issue. This bug can be closed.
