That's the default for CMake? It doesn't first check for the AirPcap SDK
(which you will *not* have if your operating system's name doesn't contain the
string "Windows")? That's definitely a bug in the CMake configuration.
The other bug is that capture_if_start() appears to completely empty out the
array of interfaces, using interface_opts as a temporary value, and then uses
interface_opts - which might not have been set, if the array of interfaces is
empty - to set airpcap_if_active. That bug was, apparently, not caught by the
compiler that's used on the only platform where HAVE_AIRPCAP should be on,
namely Windows, so I suppose we should be grateful for the other bug, which
caused this code to be run through GCC with the warnings cranked up.
I suspect that's a result of the AirPcap code being a leftover from before the
multiple-interface changes; note that this means that you might well have a
capture in progress on an AirPcap interface *and* a regular interface at the
same time, which could complicate the UI a bit. (Note that we already have
interface options that are supported on some interfaces but not others, such as
the "monitor mode" setting; AirPcap introduces more such options, and, if, as,
and when I get around to adding channel-changing support for 802.11 interfaces
to libpcap, there will be even more such options - and those options will be
similar to the ones for AirPcap.)
