You cant make functions in python and pass them into C++. I think the swig docs say something about this. Basically, the python functions are just objects, they are not functions to be called when you get into the c++ level. Maybe it can be done, but its outside the scope of what swig covers, or at least its not simple or obvious. > The reason to use python would be to avoid having the user compile stuff > and being faster in prototyping a solution.

Now you can override this block with your own work function and io signature and plug it into any generic python flowgraph. -josh _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
