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.
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.
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

I am developing an OOT. I have a preliminary version working, and now
I am working on a new version.
To make the new version, n the build directory, I first did a "sudo
make uninstall".
I changed some code in one of three block (dstar_decode_bs) in my
module as well as added two new classes (.cc and .h file) in lib. I
also added the two new cc files to CMakeList.txt file in lib.
I removed the build folder and did a cmake, make and "sudo make
install". (And "sudo ldconfig" just for good measure.)
Now I am getting the well-referenced "AttributeError" error with a
very simple test flow graph:
Executing: /usr/bin/python -u /home/tom/top_block.py

My block doesn't depend on any other block, so I don't think I have to
change GR_REQUIRED_COMPONENTS in the top level CMakeList.txt file.
You can see the working preliminary version (in the "master" branch)
and the non-working new version (in the "syncing" branch) at
https://github.com/ac2ie/gr-ambe3000. I have been searching for a
solution to the AttributeError message, but haven't found anything
useful.
