Runtime Error

I am using DVB-T dongle RTLSDR2832U with gnu radio, i have installed all
the required files, but when i compile my flowgraph I get an error.
Runtime Error:Failed to open rtlsdr device.
What is the problem and its solution??

Hello Sohaib,
from http://sdr.osmocom.org/trac/wiki/rtl-sdr:

If the device can’t be opened, make sure you have the appropriate rights
to access the device (install udev-rules from the repository, or run it
as root).

The osmo project has for your conveniences generated a rule that assigns
correct access rights to your device as soon as you plug it in. So in
your rtl-sdr build folder, run

sudo make install-udev-rules

to install them.

Hopefully that fixed your problem,
Greetings,

Marcus M
