Well,

The exception happens on this line:

uhd::device_addrs_t device_addrs =
uhd::device::find(vm["args"].as<std::string>());

the exception is:
First-chance exception at 0x0f62763b in uhd_find_devices.exe:
0xC0000005:
Access violation reading location 0x02796000

p.s:
maybe It will help if you'll write down the basic steps needed in order
to
be able to build one of the example code on your on

Thanks,
iftah

Hi Iftah,

as for the building part, you seem to be doing fine.
I'm a little perplexed, actually.
Maybe it's something like
http://lists.ettus.com/pipermail/usrp-users_lists....

where the solution was not to mix debug and release build symbols of
UHD.

Greetings,
Marcus
