Ges, when I encountered a similar imponderable I inserted import sys print sys.path
in a judicious place, just to see what path obtained at that moment. While it will not solve your immediate problem directly, it might be interesting to see what is your python sys.path when the failure occurs. > File "./qa_add_and_friends.py", line 23, in ? > from gnuradio import gr, gr_unittest > ImportError: No module named gnuradio iow, e.g., in gr-build/gnuradio-core/src/python/gnuradio/gr/qa_add_and_friends.py import sys print sys.path from gnuradio import gr, gr_unittest ... Or the moral equivalent. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
