Hi,

I’ve added a module ‘sensing’ with a “noblock” block ‘sensing’ but  
when I tried to make, I got this error:

Hi,

I’ve added a module ‘sensingmod’ with a “noblock” block ‘sensing’ but  
when I tried to call the block from python, I got this error:

Traceback (most recent call last):  
File “./tunnel\_tx\_simul.py”, line 49, in   
from sensingmod import sensing  
File  
“/usr/local/lib/python2.7/dist-packages/sensingmod/ **init**.py”, line  
45, in   
from sensingmod\_swig import \*  
File  
“/usr/local/lib/python2.7/dist-packages/sensingmod/sensingmod\_swig.py”,  
line  
188, in   
sensing = sensing.make;  
AttributeError: type object ‘sensing’ has no attribute ‘make’

I thought I had to add a function “make” to the block but still got the  
error.

Any Idea?

Regards,  
Nada

Looks like there were a couple of typos in the templates for the  
noblock. I pushed a fix for it to maint/master/next.

For your problem, just go into your swig/sensingmod\_swig.i and remove  
the GR\_SWIG\_BLOCK\_MAGIC line for this particular class. This only  
means anything for gr\_block classes.
