Re: [Discuss-gnuradio] Small example - using UHD function

[Martin Braun]

Simone,

you're asking a bit much of people who are essentially volunteers if 
they need to install several modules before they can run and test your 
code for you.

Obviously, SWIG isn't picking up the class you wrote. There can be 
several reasons for this, maybe you forgot it in your SWIG files (are 
you using gr_modtool?) or your block definition is incorrect...

I suggest you start with something simpler first, until you've learned 
the intricacies of building OOTs. We have the new 'guided tutorials' on 
the website to help you with this.
