I'm trying to debug some Cython code with gdb that is wrapping C++ code to be called from Python. I followed the instructions in the documentation but I'm getting some errors while debugging that are unrelated to my code. Example:
(gdb) cy print some_variable
Python Exception <type 'exceptions.AttributeError'> 'PyDictObjectPtr' object has no attribute 'items':
Error occurred in Python: 'PyDictObjectPtr' object has no attribute 'items'
I'm also getting this one sometimes (usually after the first one):
Python Exception <class 'gdb.error'> There is no member named ob_sval.:
Error occurred in Python command: There is no member named ob_sval.
To debug the code I created an environment with Docker:
FROM debian
RUN apt-get update && apt-get upgrade -y && apt-get install -y \
build-essential gdb-python2 python-dbg python-dev \
python-pip python-numpy-dbg
RUN pip install cython pygments
CMD bash
I found two related posts in the cython-users google group but with no answer.
