Thanks fr help & support. I re run all commands and used export command you provided and was able to install channel coding toolbox. But when I simulated the .grc file (attached with mail) I got following run time error. Traceback (most recent call last): File “/home/ehsan/mygn/top\_block.py”, line 17, in import chancoding File “/usr/local/lib/python2.7/site-packages/chancoding/ **init**.py”, line 40, in from chancoding\_swig import \* File “/usr/local/lib/python2.7/site-packages/chancoding/chancoding\_swig.py”, line 26, in \_chancoding\_swig = swig\_import\_helper() File “/usr/local/lib/python2.7/site-packages/chancoding/chancoding\_swig.py”, line 22, in swig\_import\_helper \_mod = imp.load\_module(‘\_chancoding\_swig’, fp, pathname, description)ImportError: libgnuradio-chancoding.so.0: cannot open shared object file: No such file or directory > > > DoneWhat may be the prblem Best RegardsGRB — On Wed, 1/23/13, Tom R.

Stop. Please suggest what to do now. Regards Sorry, I’m not hands-on familiar with that project. Perhaps Martin could weigh in here? Might not meant to be installed automatically, so you might have to do something by hand. Tom — On Wed, 1/23/13, Tom R.

I then tried to install Channel Coding Toolbox by following instructions given at [https://www.cgran.org/wiki/chancoding](https://www.cgran.org/wiki/chancoding) I used following commandssvn co [https://www.cgran.org/svn/projects/channel\_coding/trunk/gr-chancoding](https://www.cgran.org/svn/projects/channel_coding/trunk/gr-chancoding) cd gr-chancoding ./bootstrap But after giving./configureit shows following at the end:No package ‘gnuradio-core’ found Consider adjusting the PKG\_CONFIG\_PATH environment variable if youinstalled software in a non-standard prefix. Alternatively, you may set the environment variables GNURADIO\_CORE\_CFLAGSand GNURADIO\_CORE\_LIBS to avoid the need to call pkg-config.See the pkg-config man page for more details. I dont know what to do now. You should adjust PKG\_CONFIG\_PATH. Put it another way. Where is your GNU Radio installed to? If you compiled and installed by hand without adjusting anything, it should be in /usr/local. So then you will have a directory: /usr/local/lib/pkgconfig This directory contains package config files like gnuradio-core.pc. Point pkg-config there and you’re configure scripts should be able to find it: export PKG\_CONFIG\_PATH=/usr/local/lib/pkgconfig:$PKG\_CONFIG\_PATH Is there some other way to do this simulation. I have latest version of gnuradio installed i.e v3.6.3-6-gca407436. Best Regards GRB Tom ---
