Thanks Bastian,
I removed try/except int __init__.py and it gave:
ImportError: /usr/lib/libgnuradio-ambe3000.so: undefined symbol:
_ZN12CDStarHeaderD1Ev
I suspect this is telling about the undeclared destructor for
CDStarHeader, but I think I am to inexperienced to understand the _ZN12
prefix and D1Ev suffix!
Marcus,
Thanks! I removed the offending printf() and added an empty destructor
and can build successfully. Now I know that I have (a lot of) debugging
to do!
Do you have any idea why my system did not complain AT ALL when building
the syncing branch? I am using ubuntu 16.04 with the apt-installed grc
(3.7.9). Do I have some config screwed up somewhere?
Thanks again. I very much appreciate this support!

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

Thanks Marcus, for trying this. I tried what you suggested and there was
no love. I even tried to uninstall, then rm'ed the build folder and
rebuilt, with still no luck. You cloned the "syncing" branch, right? The
"master" branch works fine. I have gone back a couple of times to see if
I could figure out what I broke.
IIRC, I had a similar problem and removing the try/except here:
https://github.com/ac2ie/gr-ambe3000/blob/master/python/__init__.py#L30
showed the actual error message. Maybe you want to try this.
Best,
Bastian
