Tahnk you very much for your reply.  
I’ve tried different time with templates,but I was not able to obtain a  
result(cmake and make finish errors,but I suppose that swig  
crash,because  
python scripts are not able to access to any block written in C,also  
blocks  
without template)…

At the end I’ve solved thanks to \*.t files.

Templates have also another little problem: gr\_complex is declared as  
complex,while other types are more basic…so it would be  
necessary  
to write a template for “normal” types like float,short…, plus a  
template  
of template for gr\_complex
