Hi everyone,

I've created a branch of fosphor with the goal of making it compatible with GNU Radio 3.8 (specifically the maint-3.8 branch). I've branched fosphor from

https://github.com/osmocom/gr-fosphor/tree/gr38-qt5.

My branch is located at

https://github.com/the-aerospace-corporation/gr-fosphor/tree/gr38-qt5-aero

The changes are updates to the cmake scripts and modules, most of which are derived directly from the 3.8 module porting guide located at
https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_Guide

Development was performed in Ubuntu 18.04 with GNU Radio installed using pybombs and Python 3 support as described at

https://github.com/gnuradio/gnuradio

and using a prefix-based GNU Radio install. The updated fosphor branch has been tested with NVidia and Intel OpenCL. At this point GLFW works but QT does not.

To build and install the updated fosphor branch, install GNU Radio 3.8 from the maint-3.8 branch, install all dependencies as described at the fosphor wiki, then execute

git clone https://github.com/the-aerospace-corporation/gr-fosphor

cd gr-fosphor

git checkout gr38-qt5-aero

mkdir build
cd build
cmake ..
make
make install

I'm interested in the process for merging my updates back to the official repository. For instance, additional testing using different platforms might be a good idea.

Best,
