[Discuss-gnuradio] import error after re-swig-ing

[Alex Young]

I know Tom is really busy these days, so I decided to give him a break 
from all my questions and see if anyone on the list can provide some 
insight. 

background:
I have been using gnuradio 3.0 rc1 for at least one month, with no 
obvious issues.  running on ubuntu 7.04, x86

I wrote a little 1/2-rate convolutional encoder using the IT++ 
libraries, and put in gnuradio-core/general for the moment.  After 
creating and/or editing the requisite .cc, .h, .i, and Makefile.am 
files, I was able to 'make' my way all the way down the build tree to 
gnuradio/trunk with no (as far as I can tell) errors.  my code, 
gr_half_conv_enc_bb, now shows up in 
gnuradio/gr/gnuradio_swig_py_general.py at the end of all the other 
classes in the file.  I can't seem to access or use it though. 

From the python command line, this is the process I follow. 

>>>from gnuradio import gr
>>>conv = gr.half_conv_enc_bb()

and I receive the following error:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>

For the purpose of reference, I ran a line of code from the heir blocks 
example gmsk2.py at the same python prompt:

>>>self.nrz = gr.bytes_to_syms()

and I received no error message.  (bytes_to_syms is in the same 
gnuradio_swig_py_general.py file as my class.)

I don't necessarily fully understand the gnuradio make/swig process, so 
I'm not really sure where I've gone wrong.  Any thoughts or suggestions?

Thanks,
Alex Young
