Hi everybody,
I just installed gqrx version 2.5.3 on Ubuntu Linux 14.04.3 by following these instructions:
I have an RTL2832U device plugged in that worked great under gqrx 2.4.
===
andy@lctux2:~/.config$ gqrx --version
linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.009.002-release

I thought I was very careful to clean out all old libgnuradio and related libraries.
However, with version 2.5.3, the gqrx GUI never appears. When started from a terminal, this is the text output:
===

The terminal hangs at that point, and the gqrx GUI never appears. I can recover the terminal with ctrl-C.
Any suggestions will be greatly appreciated.
Thanks,

Andy,
1) my commiserations
1A) presumably your system is kept up-to-date
2) you have no previous default.config from your old installation, and GQRX is trying to ask for some information to know which device to use, its parameters &c.:

the point at which a dialog box is thrown up to configure

4) the UI that appears (should appear) at this point is a dialog box. It sounds as if it's being hidden on your system, perhaps covered by another window. It should look similar to:
5) after selecting OK, the main GUI should then appear, waiting for you to click the
button!6) if a hidden dialog box is not the problem, then, not knowing the gory specifics of your current system and what may or may not have been compiled locally, via script or otherwise. For instance, there might be stray Qt libraries, since little of GNURadio has been invoked at your failure point. The guaranteed answer is to perform a clean install of Ubuntu. And then add gqrx and all your other favourites. (For myself, I use a set of scripts to install various PPAs, other repositories, and packages on various machines.) YMMV, of course!
HTH,

The only time I have seen something similar was when someone tried to
run gqrx remotely using remote X-server. But it doesn't sounds like
you are using any unusual setup wrt. to graphics, so I have no idea.

HI Alex,
Thanks for the reply. Are there any debug switches that I can pass on the command line that might give us more information?
Failing that, I could try compiling the 2.5.x source code. If I encounter the same result, I could imagine adding debug messages to the source to isolate the issue.

UPDATE: compiling directly from source has worked flawlessly for me! I'm still puzzled by the earlier issue, but happy that the software is now working. I use it alot and find it very enjoyable. Thanks for all of the hard work to make this possible!

Hmmm, a bit strange but OK...
Did you build against the same Qt version as the one used by my binary?

HI Alex,
The Qt version against which I built gqrx is libqt4, specifically some long ubuntu-ish version:
4:4.8.5+git192-g085f851+dfsg-2ubuntu4.1
(that's for libqt4-core)
I used qmake to build the software.
My computer is running "Andy's Ham Radio Linux" which is largely based on Ubuntu 14.04.3. Yes, I'm that "Andy". :-)
