[BUG] Maplotlib fails to install from source

[nithinivi]

setuptools version

65.5.0

Python version

python 3.10.6

OS

Ubuntu 9.4.0-1ubuntu1~20.04.1

Additional environment information

conda 4.12.0
gcc version 9.4.0

Description

Attempt to build an editable install of project Matplotlib encounters an internal compiler error referencing PEP 660.

While using the suggested workaround with environment variable SETUPTOOLS_ENABLE_FEATURES="legacy-editable" subprocess-exited-with-error is encountered.

References to similar issues:

#3644 SQLAlchemy editable install failure references setuptools PEP 660
#3606 [Question] Editable install fails after introducing pyproject.toml
#3607 [BUG] If you are seeing this error, please report to
#3597 Struggling with fairseq installation

Expected behavior

The expectation is no error and a successfully built editable install.

How to Reproduce

git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
conda env create -f environment.yml
conda activate mpl-dev
python -m pip install -ve .

Output

>> python -m pip install -ve .

Hi @nithinivi thank you very much for reporting this.

Could you please confirm that a "non-editable" installation works without any problem? (i.e. following the same steps you described in the "How to reproduce" section from scratch but replacing the installation command with python -m pip -v install . (no -e flag).

[nithinivi]

@abravalheri Hi thanks for the response. On trying "non-editable" I'm getting the same I am getting the following error

[abravalheri]

Thank you very much @nithinivi.

Since the non-editable install and the legacy install all fail to build with the same problem, I think we can rule out the hypothesis that this is caused by the PEP 660 implementation in setuptools.

---

I tried to reproduce the error with the following procedure:

git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
conda env create -f environment.yml
conda activate mpl-dev
python -m pip -v install .

In my dev machine with Ubuntu 20.04.5 LTS and Python 3.10.6 (created by conda), I can install the project from the source code without experiencing the error you describe:

Successfully installed matplotlib-3.7.0.dev508+g5c58816e41

I can also install it using the editable mode:

python -m pip -v install -e .

and everything still works fine:

Successfully installed matplotlib-3.7.0.dev508+g5c58816e41

---

Next, I tried to run the procedure in a container:

> docker run --rm -it condaforge/mambaforge /bin/bash
# mambaforge image should be based on Ubuntu Focal Fossa

apt update
apt install -y autotools-dev autoconf make build-essential
cd /tmp
git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
conda env create -f environment.yml
conda activate mpl-dev
python -m pip -v install .
# ...

Successfully installed matplotlib-3.7.0.dev508+g5c58816e41

I was also able to do an editable install inside the same container:

python -m pip -v install -e .

Successfully installed matplotlib-3.7.0.dev508+g5c58816e41

---

Is there any chance you can share with us a reproduceable isolated environment that results in the error you are seeing (ideally in a container)?

I am starting to suspect that this problem might be dependent on the dev environment...

[abravalheri]

I am renaming the issue to reflect the latest findings.

[drammock]

@abravalheri I just followed your procedure exactly, and I'm failing to build matplotlib:

git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
conda env create -f environment.yml
conda activate mpl-dev
python -m pip -v install .

(actually I already had an up-to-date clone so I skipped the git clone line, but the rest I did exactly as you).

Here is the tail end of my failure with non-editable install (as above):

A thing that jumps out to me is that these errors are happening when a mix of the system and conda compiler tool chains:

[drammock]

I fixed this by rm -rf build/* and then retrying python -m pip install -e . just worked. So, with a clean clone of matplotlib I cannot reproduce.
