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,

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,
