Re: [Discuss-gnuradio] modifying how-to-write-a-block 3.2.2

[Affan Syed]

Tom,
most of my problems have to do with compilation i.e. my new block  
doesnt compile as somewhere there is a reference to the old how_to  
module structure. I didnt add any errors since I think I had attempted  
a very large change in one go (i.e. changed the code and module name  
and pared down from two classes to just one) and I can solve the  
problem by incrementally changing just one thing at a time. I still  
think I should be able solve this if I give it another 3-4 hrs  
(probably tomorrow) but was hoping to see if someone updated the howto  
that works for older versions.
