python setup.py build (in parallel)

   January 23, 2021  2 Comments on python setup.py build (in parallel)

One bottleneck for development is a lack of ability for parallel compilation – which is something that’s true for all extension code (I think this is due to a limitation in distutils / setuptools / etc). I know I’m not alone in having tried to do this before, but I just came across this SO post suggesting a way to monkeypatch distutils into submission for this purpose, so perhaps someone’s feeling optimistic and wants to give this another stab?

  1. Thanks for the tip, sounds reasonable to me, closing.

    Just to document how one can use ccache when installing matplotlib from source:

    CC="ccache gcc" python setup.py install

  2. Just to follow up with this ancient thread, the following works a treat for me on a mac:

     CC="ccache gcc" CXX="ccache" pip install -e .
