Pillow : missing lib #129

Closed thrynir closed 4 years ago

thrynir commented 4 years ago

Package name: Pillow Link to PyPI page: https://pypi.org/project/pillow Link to piwheels page: https://www.piwheels.org/project/pillow Version: 7.2 Python version: 3.7 I am the maintainer: No More information:

Hi,

Wheels add a directory pillows.libs to add all requested libraries to run pillow. But you are asking to install it with apt. Can I ask why you choose that way ?

When we build a wheel, we run this process on the file to see which libraries are required, and which packages provide them.

What do you mean by this?

Well, maybe I just don't understand the all process.

My issue is if I run a pip install pillow on x86-x64 I get 3 directories in dist-packages PIL, Pillow.libs and Pillow-7.2.0-dist-info

With piwheels, I only get PIL and Pillow-7.2.0-dist-info and so I can't import PIL as there is some missing librairies. As you explain in piwheels page (https://www.piwheels.org/project/Pillow/) I have to install all the libraries manualy with apt. Except I would like ta have the same process I have with x86-x64.

What I missed ?

piwheels is an automated system - we run pip wheel package==version for every version of every package and make the resulting wheel file available for download. We don't really have the ability to customise the build. It looks like pillow provide a build option which bundles the dependencies, and the x86_64 wheel they provide for Linux has been built this way, but it's not the default so the one built by piwheels is a standard build.

Ok, thanks for your answer
