gr-fosphor on OSX & GNURadio 3.8

Hi, I'm trying to build gr-fosphor on OSX, GNURadio 3.8 & Python 3.7.10 (built from Macports) but it blows up in a swig wrapper: [ 80%] Building CXX object swig/CMakeFiles/fosphor_swig.dir/CMakeFiles/fosphor_swig.dir/fosphor_swigPYTHON_wrap.cxx.o warning: unknown warning option '-Wno-format-overflow'; did you mean '-Wno-shift-overflow'? [-Wunknown-warning-option] /Users/oconnd1/projects/gr-fosphor/build/swig/CMakeFiles/fosphor_swig.dir/fosphor_swigPYTHON_wrap.cxx:5219:14: error: no viable overloaded '=' result = gr::fosphor::glfw_sink_c::make(); ~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Full build log is at https://gist.github.com/DanielO/8a75d1cc2848f773e702d788fa8275b8 I ran cmake like so: cmake -DGR_PYTHON_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages -DCMAKE_INSTALL_PREFIX=/opt/local -Wno-dev .. I am happy to test any patches etc but unfortunately my C++/Swig skills are nonexistent :( Thanks. -- Daniel O'Connor "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum
