Deprecation warning in build process

[jzwar]

Running the build on splinepy prints the following warning (Ubuntu, python 3.9)

<path>/site-packages/setuptools/command/easy_install.py:144: EasyInstallDeprecationWarning: easy_install command is deprecated. Use build and pip and other standards-based tools.
  warnings.warn(
<path>/site-packages/setuptools/command/install.py:34: SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and pip and other standards-based tools.

Is this an issue with my installation or a common problem?

[clemens-fricke]

Sorry for the late answer. Calling setup.py is being deprecated apparently. Just yesterday I found a workaround for the "--minimal" option that needs to be added during most installs.

After a quick look around I found this blog post:
https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary
It would be great if @j042 @jzwar could also look into it so that we can together decide if this is something we need to update or if we can live with the current -- now apparently deprecated -- workflow.

[clemens-fricke]

From what I read we can just go to pip install . or pip install -e .. If the --minimal option is needed the following can be appended --install-option="--minimal".

For package build there seems to be a build package which can also use the configurations in existing setup.py files. (Hopefully just drop-in replacement)

But as I understand it, it might be better to move towards a pyproject.toml approach (the primary way to use the build package) in the future.

[clemens-fricke]

Ok after, (somehow) my pip updated, the previous --install-option is no longer available for the pip install command. But now you can do --config-setting="--build-option=--minimal".

I am not sure why they are abstracting it further and further.

[j042]

Maybe it is time to move to skbuild

I am also getting an error when trying to build splinepy (WSL, Ubuntu, python 3.9).
Tried the following command:

python setup.py develop --config-setting="--build-option=--minimal"

and got following error:

************* build options ************

  cmake_args: {
    --verbose_make: -DSPLINEPY_VERBOSE_MAKE=OFF
    --minimal: -DSPLINEPY_MORE=ON
    --enable_warning: -DSPLINEPY_ENABLE_WARNINGS=OFF
    --no_explicit: -DSPLINEPY_BUILD_EXPLICIT=ON
  }
  build_args: {
    --serial_build: -j 12
  }
  --debug : False

Also tried:
python setup.py develop --install-option="--minimal"
but got the same type of errors (option ... not recognized)

and with:
python setup.py develop --minimal --enable_warning

i got:

************* build options ************

Do you have any further ideas?

[j042]

Do you have any further ideas?

I am working on updated build now, PR should be ready some time soon.
python setup.py develop --minimal should still work. Have you tried deleting all the previous build artifacts?

[FSchwar]

Hm, I´m getting the warnings/error like mentioned above in the last section.
But i didn't try to delete anything prior to building it - how would I delete those artifacts?
