Hi all, This is a known issue - unfortunately I just haven't had the time to make necessary modifications (will do so now), but the temporary work-around is to symlink: /usr/local/include/gnuradio/swig/gruel_common.i -> /usr/local/include/gruel/swig/gruel_common.i The new version will be in the gr-baz repo hopefully very soon.

Hi all, A couple of updates: . gr-baz (git & SVN) now contains the fix to the issue regarding the 'gruel_common' compilation error (thanks Alex Csete). . The OP25 block now first tries to use the op25.fsk4_demod_ff, and then falls back to fsk4.demod_ff if the former is not found. . For those experimenting with OP25 and the RTL DVT-B USB dongles, I've started a Google Group <https://groups.google.com/forum/#!forum/ultra-cheap-sdr> for discussion surrounding the device, and its use with gr-baz/GNU Radio/plugin on Windows. Regarding the error seen by 'allanjs1986' in GRC: Type "msg" is not a possible type. I'm a little worried about this - are you using the latest GRC? I thought message queues (specified by the 'msg' type) were still around. does anyone know more? If you need a workaround, then just comment out/delete the last <source> block (name: 'tune', type: 'msg') in gr-baz/grc/op25.xml, do a sudo make install, restart GRC, and remember to set 'Output auto tune' to 'No' in the OP25 decoder block properties.

I've just accepted the git pull request submitted by Alex Csete (thank you!) to fix the build issue on v3.6 of GNU Radio (tested by 'zignig'), so if you grab the latest, hopefully this issue will disappear! (If other people have encountered this problem, please let them know too.)
