** Hi everybody I'm a graduate student working on a project and I have to realise a reception with an USRP of P25 standart communications. I have basics knowledge in linux and I have been struggeling those days to make work gnu radio and gr-baz (with op25 module..). I tried many distribution: Ubuntu 12.10/ 32 and 64 bits and now I'm on Ubuntu 12.04 (64) and still have problem while compiling gnu radio.. I understood that there are a lot of dependency problems due to the different versions of Ubuntu and gnuradio. My question is simple, wich Ubuntu version should I take in order to make the gnuradio build script work without problems and gr-baz get installed without issues? Thank you very much Souf
