Re: [Discuss-gnuradio] The AttributeError problem now that I have modified a working OOT

[Marcus Müller]

HI Tom,

this usually implies that SWIG, for some reason, can't/doesn't wrap the
class (dstar_decode_bs, in this case).

Now, I've taken the liberty to try and build your OOT myself, and I can,
without problem, create a dstar_decode_bs object from python.

Soooo maybe it's just SWIG messing with us. Can you go back to your
build directory, make uninstall; make clean; make; make install and see
if that fixes it? SWIG sometimes behaves erratically in the presence of
previous build remains.


Best regards,

Marcus
