[maemo-developers] WLAN Scanning problem

[From: kalle ahokangas]

Thanks for your response very much.

>You scan using wireless extensions directly, right?
Yes that's right.

The problem now is that the osso-wlan package does not complile. The error
is wlancond-dbus.h and wlancond.h files are not found. I checked the package
and they are not there. From where I can find them?

I'll need these files when using the osso-wlan DBUS interface.Right?

It would also be great if someone can provide simple example for using the
osso-wlan DBUS interface for scanning.
