Installing GQRX on Ubuntu

[Ryan Lanham]

I followed the instructions at http://gqrx.dk/download/install-ubuntu for installing GQRX.
However, when I enter

gqrx

into the command line after the install, I get an error saying:

gqrx: error while loading shared libraries: libgnuradio-runtime.so.3.7.9: cannot open shared object file: No such file or directory

I looked back through the terminal during the install and saw that this command

sudo apt-get install gqrx-sdr

installed libgnuradio-runtime3.7.10

I'm confused on why the a new version of the libgnuradio-runtime is being installed but gqrx requires 3.7.9


Additional Info:

I've linked a google doc showing the data in the terminal following the "sudo apt-get install gqrx-sdr" command
      https://docs.google.com/document/d/14Eo22-fo-6F9fePJoDJA7_AMD4_f5AygkDrrEtvhw70/edit?usp=sharing

I attempted a source code install prior to attempting the Ubuntu Linux binary. I also entered the purge commands shown on the downloads page prior to attempting to install.

I'm on Ubuntu 16.04


Any help would be significantly appreciated.
Thanks

The purge command can only remove packages installed from ubuntu
repositories. The ubuntu package manager has no idea what people
install from source and where they install them. So you have to remove
your source installation yourself

Alex,

Thank you for responding. I'm pretty new to Linux and I was attempting to install the dependencies noted in the Gqrx Source Code README file.

I'm trying to figure out how to uninstall the dependencies, as I think that one of them is where the libgnuradio-runtime is coming from.

Some of them are pretty simple (e.g. Qt has a ./MaintenanceTool that will remove their software), however, some of them don't seem so straightforward.

I think what I should do based on the error is find the libgnuradio-runtime file wherever it is on my drive, then delete it, and then try the install again.

Is that where you would start?

For each package you have installed from source, you have to go to the
directory where you typed "make" and "make install" and now type "make
uninstall". That's all I can say.

If you can't make it work and do not wish to reinstall your system,
you can try the Generic Gqrx binary package for 64 bit linux:
