Well,
The exception happens on this line:
uhd::device_addrs_t device_addrs =
uhd::device::find(vm[“args”].asstd::string());
the exception is:
First-chance exception at 0x0f62763b in uhd_find_devices.exe:
0xC0000005:

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

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.ettus.com/2013-September/007415.html
where the solution was not to mix debug and release build symbols of
UHD.
Greetings,
Marcus

Thanks again, Kiran
Sounds plausible. Ctest is actually just running a shell script.
You can try running that script through gdb. The name of the script
will be printed near the top of ctest -V. Alternatively you should
be able to find it in
$build/modname/python/namespace/qa_whatever_your_test_is_called.sh;
an example for gr-digital:
[Discuss-gnuradio] ctest -V segfault, coredump reveals nothing
build/gr-digital/python/digital/qa_mpsk_snr_est_test.sh
figure out why this is going on, but atleast I know where to start
