Hello, I have tried both python -c "import..." and echo $. I see the path to my folder in both of them. But it still says ImportError in top_block.py. Where exactly should the path direct to? I tried both "~/gnuradio" and "~/gnuradio/myblock".
When you say __init__.py do you mean the one in sub-folder "python"? I find this comment in that file: # The presence of this file turns this directory into a Python package. I am wondering where I could see the declare of my module. To Mike: yes, I am in Ubuntu 10.04 Many thanks to your help.
