gr-fsk4 install Error: Unable to find 'pmt_swig.i'

becuase i am stuck on this on an error (AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback') i decided to try to build again. when trying to install the 4fsk demodulator i get this error: make[2]: Entering directory `/home/matt/gr-fsk4/src/lib' /usr/bin/swig -c++ -fvirtual -python -modern -I/usr/local/include/gnuradio/swig -I/usr/local/include/gnuradio -module fsk4 -o fsk4.cc ../../src/lib/fsk4.i /usr/local/include/gnuradio/swig/gr_basic_block.i:26: Error: Unable to find 'pmt_swig.i' note that when i run op25 the first output line is "Imported legacy fsk4". so now i am confused as to how grc is importing the fsk4 if i cant even install it? Cheers, Matt

Error: Port has too many connections.

if i don't disable the 'raised root cosine filter' then i get this error in the op25 properties box: Sink - bb(0): Port has too many connections. i already had to disable the 'wx gui fft sink' to get rid of the "AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'" error which i believe stops the op25 python gui from running. has anyone else had to deal with this "too many connections" error? thanks guys!

re displaying the raw IMBE data
by lynnolium2005 03 Mar '13

03 Mar '13

After a long time I have finaly got OP25 working, my thanks to the people who helped get it going and the numerous posts here that clarified issues. there is one change I would like to make to the code. this is to change the way the data is either displayed by wireshark or a new start command that will display the 88 bit rew IMBE data rather than the 144 bit interlaced data. I have been told that OP25 will display the data in thuis format but I will need help (step by step if possible) to do it

updated build instructions

Folks Sorry for the pain - tried replying to Doug but that message may have been killed, not sure. Anyhow, I've updated the repeater wiki page with instructions for building a CLI-only version of asterisk - the prereqs for doing so should be very minimal. The asterisk CLI version is what I've always used (having started using * when there was no GUI) - ymmv. Max

Full asterisk support?
by n4dav 27 Feb '13

Hi Folks, new here.. Did a lot of looking around, but didnt see the answer to this. I want to use app_rpt as my repeater controler and support P25 + NBFM. I see a rx-to-asterisk app here, but not a corresponding asterisk-to-tx app. I saw a repeater app but didnt appear to support asterisk. Am I missing something or does it not exist? Thanks!

Exception running OP25
by md123＠nycap.rr.com 27 Feb '13

I am using using ubuntu 12.10 i am trying to run OP25 (python version 2.7.3), in GNU Radio Companion v3.6.3-35-g4435082f and i get an error. So I run the traceback command in terminal: ~$ python -m trace --count -C . op25_grc.py Here is the output with an error: Imported legacy fsk4 Using Volk machine: ssse3_32 Traceback (most recent call last): File "/usr/lib/python2.7/runpy.py", line 162, in run_module_as_main "_main__", fname, loader, pkg_name) File "/usr/lib/python2.7/runpy.py", line 72, in run_code exec code in run_globals File "/usr/lib/python2.7/trace.py", line 819, in main() File "/usr/lib/python2.7/trace.py", line 807, in main t.runctx(code, globs, globs) File "/usr/lib/python2.7/trace.py", line 513, in runctx exec cmd in globals, locals File "op25_grc.py", line 493, in tb = op25_grc() File "op25_grc.py", line 231, in __init_ self.wxgui_fftsink2_0_0.set_callback(wxgui_fftsink2_0_0_callback) File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 54, in getattr return getattr(self._hb, name) AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback' I really really want to get OP25 running but have not been able to figure out what is the solution to this error (AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback') . it'll take me ages to figure out how to debug in python. some threads have said its because gnuradio is an older version but in my case it is not. i am wondering if the question is too amateur or something because nobody is lending assistance. Any help will be so very much appreciated. Thanks.

Runtime error- ioctl(d_tap, TUNSETIFF, &ifr): Operation not permitted

Has anyone seen this error? i cant find anything on the web about this. I already had to disable the Waterfall sink and the FFT sink in order to get rid of the "AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'" error. Now OP25 dies this way: Imported legacy fsk4 Using Volk machine: ssse3_32 RTL2832 Source block configuration: Read length (bytes): 262144 Buffer enabled: yes Buffer multiplier: 8 Buffer size (samples): 1048576 Samples per read: 131072 Buffer level: 50.0% Successfully initialised demod: "ezcap EzTV" Probing "e4k"...not found.

I installed GNUradio using the build script on Balint's "how to build page" but OP25 I had to build from source because the build script there has a broken link. Any help will be much appreciated.

Does anyone know the command (using ubuntu) to permanently add a directory to the PYTHONPATH? Thanks in advance.
