GNU Radio version

Question

How do I find out the version of GNU Radio that I have installed?

I would like the use their messaging libraries, but they are available on newer versions of gnuradio only and for some reason I'm getting a compilation error when I try to use the following code:

message_port_register_out(pmt::mp("out_message"));

I get the following error on compilation:

error: ‘message_port_register_out’ was not declared in this scope

It's supposed to be part of the gr_basic_block, which all blocks inherit from, but it's not compiling.

Solution 1

You can get the version number using python.

from gnuradio import gr
gr.version()

Solution 2

If you installed the complete package - not only the library - in a terminal window:

$ gnuradio-companion --version

GNU Radio Companion 3.7.2.1

or

$ gnuradio-config-info --version
3.7.2.1

Well, what about the first part of the question. How do I find out the version of gnuradio i have installed?

[jortiz81]

It's written in the constructor of a source block.

Not knowing much about your particular system setup, the best I could offer is a find command. Something like find /usr/lib -name 'lib*radio* - this should yield you some result like libgnuradiosomething.so.3.61 or something similar. Sorry I can't be more precise here. Also check /usr/local/lib

Cool, I will try that. Thanks Ron.

I'm not aware of any distribution that would offer the GNU Radio library without gnuradio-config-info, but I do believe that such exists. Can you enlighten me on where that happens?

Wow, this was a year ago! I believe I meant that gnuradio-companion might not always be available. That's what the reply said too: The idea is that the library is always available, but not always grc. It's been a while, but I believe grc can be disabled from configure
