Hi Vinay,

your mail from an hour ago reached the list just fine :) Please don't
repost the same questions this fast; it just confuses people.

So, this looks like none of the gr-radar blocks have been installed.

Now, this is a bit strange, because the current version of the LiveDVD
comes with gr-radar preinstalled, so you're probably using an old
liveDVD and did not install gr-radar, or you made a new user on the live
systemand forgot that you'll need to build and install gr-radar there
locally. Looking at your path, I'd say this is the most likely problem here.

So, easiest course of action is log out as user "vinay" and log back in
as user "ubuntu" (empty password). You'll find gr-radar preinstalled,
and you'll find the examples (among with the rest of the source code)
under /home/ubuntu/src/gr-radar

The liveDVD was designed to be used as is in a single-user environment,
so when you add a new user (vinay), none of the installed GNU Radio
Out-Of-Tree modules are available, and you will need to install them by
hand, after installing pybombs.
Now, that is kind of the opposite of why you'd want to use the LiveDVD.
If you need to have your own user, with its own files, I'd recommend
*installing* a "normal" Linux (Ubuntu 15.10 or 14.04.3LTS, Debian,
Fedora, CentOS 7,... doesn't really matter, whatever suits your taste
best), and install GNU Radio and gr-radar there using the pybombs
utility; you'd have to do nearly the same thing to get everything
running as vinay on the liveDVD. Again, if you just want things to work,
simply use the default "ubuntu" user.

Best regards,
Marcus
