Re: Building From Source On Linux

[Ron Economos]

You have more than one problem.

1) There are many more than 32 tests. This indicates that you haven't 
built all of the components. When you run cmake, check the output at the 
end. It should look similar this.

If you have a lot of disabled components, you're missing dependencies. 
This is also why you only have gnuradio-config-info in your bin directory.

2) When you install to a custom directory, you have to tell the system 
about it. On Ubuntu, I use two files:

/etc/ld.so.conf.d/gnuradio.conf

This file contains the line (adjust for your install directory):

/opt/gnuradio-3.11.0git/lib

/etc/profile.d/gnuradio.sh

This file contains (adjust for your install directory and Python version):

#!/bin/bash
# add gnuradio to path
export PATH=$PATH:/opt/gnuradio-3.11.0git/bin
# add gnuradio python libraries to python search path
if [ $PYTHONPATH ]; then
        export 
PYTHONPATH=$PYTHONPATH:/opt/gnuradio-3.11.0git/lib/python3.11/site-packages
else
        export 
PYTHONPATH=/opt/gnuradio-3.11.0git/lib/python3.11/site-packages
fi

3) You need to uninstall the package manager version.

sudo apt-get purge gnuradio

sudo apt-get purge gnuradio-dev
