by Amir Jr 18 Apr '14

I have download one sample from osmocom speech codec http://tetra.osmocom.org/trac/wiki/Speech_Codec. I have compiled it sucesssfully then the output "ccoder.exe" and "cdecoder.exe" have been built. When i try to run the sample exe file using the command line, it show Segmentation fault (core dumped). This is the how i'm running the sample "./ccoder.exe sample.wav sample2.wav". I'm very confusing about the input and the output file. What is the correct type file for input and the output. Thank you for any respond

So i decided i lift the cat on the table again and start poking around with some tetra signals. first i had to use dos2unix on the python files (odd i know) once it finally found python i get this Traceback (most recent call last): File "./170913/src/demod/python/fcdp-tetra_demod.py", line 5, in <module> from gnuradio import gr, gru, audio, eng_notation, blks2, optfir ImportError: cannot import name blks2 i poked around some with the code but i ended up causing more damage then i was fixing so i thought i ask if there will be an update anytime soon? if i understood correctly blks2 is moved into 'gr-digital' Janne Lukkarinen OH2-EKO JLxSolutions
