Hi,

hostapd-0.6.4 compiles, the git version too, and links against the 
current libnl that I simply downloaded from the official page. What
errors did you get ?

I've had compilation troubles on the libnl git version (some files like
libnl-2.0.pc did not exist, but I'm completely new to git: I may have 
missed smthing), but compilation of hostapd fails (some prototypes do 
not match):

driver_nl80211.c:2002: error: too few arguments to function 
`genl_ctrl_alloc_cache'
driver_nl80211.c:2002: warning: assignment makes pointer from integer 
without a cast

Promising !..
Is the git version better than the dayly CVS snapshot ?

This might make a difference (?)
I will try that too.
