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.
