While compiling current SVN checkout I get:

I tried to fix it by changing #include <wireless.h> in driver_madwifi.c to #include <linux/wireless.h> but that didn't help much as now I get:

hostapd needs wireless-tools development files installed in STAGING_DIR, this step is done when compiling the wireless-tools package.

I believe the problem has been fixed by changeset:2449 in trunk, can you confirm ?

Hi Nico,

Can this be enabled by simply selecting:

'BR2_PACKAGE_MADWIFI_TOOLS=m'

in the kernel .config?

Many thanks,

C.
