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.

You can get the version number using python.
from gnuradio import gr
gr.version()
其他提示
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
According to the docs, message_port_register_out is a member of gr_basic_block. Based on the compilation error you have posted and the code snippet, I'd assume you need an instance to work with. It's hard to tell without more context however.
