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

Hi!

nope, I've tried the master branch only :/

but: syncing fails to build at all for me:

After adding the necessary #include <cstdio> I got a linker error:

libgnuradio-ambe3000.so: undefined reference to `CDStarHeader::~CDStarHeader()'

A-ha! your DStarHeader.h declares a destructor, but you never implement
it; so either remove that declaration in the header, or add an actual
implementation!

With those two modifications [1] instantiating ds_decode_bs works on the
syncing branch for me.

Cheers,
Marcus
