Did you use the Boatbod version / method? It's a lot easier.I tried to get this working. I couldn't get gnuradio to work. I'm no linux expert though.
I first tried installing gnuradio the standard way through packages. Didn't work. I tried compiling from source and found quite a few things missing to do even that, after fixing them it seemed to work but yet op25 still had errors related to gnuradio (although different ones) after I finally got it to compile.
I might try again, but it seems like it won't be very straight forward at all, if it will work.
I did this with ubuntu on WSL.
I hit the same wall with it - also it is tough working with just a command line with no form of interface.After quite a bit of tinkering, I have not found a way to make it work. I installed the boatbod version of op25 and the install worked, but I ran into the issue of getting ubuntu to recognize the rtlsdr. Using lsusb doest't produce anything, so the big hurdle will be getting the sdr into ubuntu. I did see an article that WSL supports serial devices, so that could be an option?
