Re: Help with Lintian error in python3 (pybind11-wrapped) package
Thanks a lot, Andrey, for the time analyzing the problems here, and
for the clarifications. I thought libpython was like "libc" for
python...
So the main issue seems to be dh_python3 not recognizing the package
as "python"...
I attach the list of files and directories of the latest package
version just in case it's easy to spot problems from it (the
"__pycache__" are there for a test Ubuntu build, but are not in the
Debian build).
Note that I want to ship:
- A cpython .so module + its .pyi stubs.
- The corresponding py.typed file, which I understand is
recommended/mandatory when shipping .pyi stubs.
- Pure python scripts (right now, only "ros_bridge.py").
At present, I put everything under
"/usr/lib/python3/dist-packages/mrpt/" so everything is together, not
"polluting" the "dist-packages" directory.
Maybe the package should be named "python3-mrpt" instead?
Any way to test dh_python3 manually? Perhaps just build the package
locally and run dh_python3 from the pkg root directory?
Best,
JL

Description: Python interface to the MRPT package (Python 3)
The Mobile Robot Programming Toolkit (MRPT) is an extensive, cross-platform,
and open source C++ library aimed to help robotics researchers to design and
implement algorithms in the fields of Simultaneous Localization and Mapping
(SLAM), computer vision, and motion planning (obstacle avoidance).
.
This package contains Python 3 wrapper of the C++ MRPT libraries.
