It looks like it was a permission problem to open gnuradio-companion. If I run "sudo gnuradio-companion," it will open correctly.
Having said that, I am seeing another problem of "No module named tutorial" when running python grc flowgraphs. On a previous computer that successfully ran the same program, I noticed that /usr/local/lib/python2.7/dist-packages contained: pavan@pavanlabdesktop:/usr/local/lib/python2.7/dist-packages$ ls easy-install.pth PyYAML-3.11-py2.7-linux-x86_64.egg future-0.15.2-py2.7.egg setuptools.pth gnuradio thrift grc_gnuradio thrift-0.9.3-py2.7.egg-info osmosdr tutorial pmt volk_modtool PyBOMBS-2.1.0rc1-py2.7.egg The one that I am currently using sees the module problem, and only contains the following in /usr/local/lib/python2.7/dist-packages: pavan@pavan-ThinkPad-T430:/usr/local/lib/python2.7/dist-packages$ ls easy-install.pth future-0.16.0-py2.7.egg PyBOMBS-2.3.1a0-py2.7.egg PyYAML-3.12-py2.7-linux-x86_64.egg setuptools.pth I don't know what was the difference in installations or how to make it work like the previous one and contain all of the proper libraries. Please let me know. Thank you so much. -- Pavan
