I think it is something to do with opengl sinks being the default now. You could try usrp_p25_rx_gl.py, but it won't work with any gnuradio version later than 3.4.2 as it uses the gnuradio usrp module, which is now deprecated and has been replaced by uhd.

I had the same issue that I saw a couple other people post about with adding an include of stddef.h to op25.cc. After that everything built as far as I can tell.
