[Quantlib-dev] Building python wheels

[Achilleas M. <mic...@gm...>]

Hi!

I'm trying to expose in Python features of the QuantLib that are not yet in
the Quantlib-SWIG.
For that I've forked the later and I've done my changes. Now I need to
compile a python wheel and provide it as a pip install-able package, to use
in my project.
I want, pretty much, to replicate the process that creates
the QuantLib-Python deliveries in PyPI.

I've noticed that the Quantlib-SWIG has a CI configuration setup for
testing, though not for building wheels for PyPi. The build/test script
looks like this:

./autogen.sh \
&& ./configure PYTHON=/usr/bin/python3 CXXFLAGS='-O1' \
&& make -C Python \
&& make -C Python check \
&& make -C Python install \
&& for i in Python/examples/*.py ; do echo $i && /usr/bin/python3 $i ||
break -1 ; done

I added the following commands at the end:

&& cd Python &&  /usr/bin/python3 setup.py bdist_wheel

Aiming to recover the .whl in the travis worker and publish it.
Unfortunately, the command gives me the following error even though the
same works as expected on my machine (Ubuntu 18.04).

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: invalid command 'bdist_wheel'

Could someone help me figure out why in the docker container the command is
not recognized but it is on my machine?
By the way, how are the wheels posted on PyPi get generated? Is it manually
or there is a CI process?

Kind regards,
Achilleas
