How did you create your project? Did you use "create-gnuradio-out-of-tree-project myblock"? If you did, you should be able to: cd myblock ./bootstrap ./configure make sudo make install and then python -c "import myblock" Otherwise, you're going to have to go into the howto-write-a-block directory which you cloned, and edit the SWIG stuff to change all the "howto" references to "myblock", and that is going to be a pain. Try re-creating your project using create-gnuradio-out-of-tree-project, it's the recommended way to start your own block project. --n > > To Mike: yes, I am in Ubuntu 10.04 > > Many thanks to your help. > > On Wed, 2011-04-20 at 16:43 -0700, Josh Blum wrote: > > > > On 04/20/2011 04:42 PM, yulong yang wrote: > > > On Thu, Apr 21, 2011 at 7:17 AM, Josh Blum <j...@joshknows.com> wrote: > > > > > >> > > >> > > >> On 04/20/2011 03:00 AM, Yulong Yang wrote: > > >>> Hello, > > >>> > > >>> I am new to GNU radio.
