Raspi op25 installation

[n1moy]

2024.Sep.02

Pursuing clarification on the current op25 Raspi build instructions.

Raspi 4B with full 64-bit debian OS [Bookworm] image with:
cmake [v3.25.1]
gnuradio-dev [v3.10.5.1-3]
gqrx [v2.17.5-4-g25fdbb5]

Is this op25 install procedure correct ?

$ git clone GitHub - boatbod/op25: Fork of osmocom OP25 by boatbod
$ cd op25
$ git checkout gr310
$ ./install.sh

Are all the required prerequisites included in the script ?

Thanks in advance,

Yes, install.sh will install all required prerequisite dependencies after switching to the gr310 branch.

Was inquiring if the 'gr310' branch was still preferred.

It's not a matter of preference. You have to select the correct branch to match the GNU Radio version that your OS will install.
To determine this information, query the apt repository. IE: apt list | grep gnuradio-dev

Example-1 (master branch)

$ apt list | grep gnuradio-dev

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
gnuradio-dev/oldstable 3.8.2.0-14 armhf

Example-2 (gr-310 branch)

$ apt list | grep gnuradio-dev

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
gnuradio-dev/jammy,now 3.10.1.1-2 amd64

You might want to try using DragonOS...Someone on the forum recommended it and it installs like a breeze with the Boatbod version.

Very interesting! My use of 'git checkout gr310' appears to be okay. Thanks,

$ apt list | grep gnuradio-dev

Yes, you do want to be using the "gr310" git branch with gnuradio-3.10 or later releases.
