Problem compiling binaries in macOS

[pablomm]

Describe the bug
Problem compiling C code from fdasrsf:

error: $MACOSX_DEPLOYMENT_TARGET mismatch: now "10.14" but "10.15" during configure

In the fdasrsf package it is fixed the variable with os.environ['MACOSX_DEPLOYMENT_TARGET'] = '10.14' in the setup.py. After cloning the repository and remove the line I get the same error.
I tried to export the environment variable before running the installation with no success.

Complete trace:

To Reproduce

virtualenv venv
source venv/bin/activate
python --version # 3.8.8 and also tried 3.9.2
pip install scikit-fda

Also, it is happening when the package is installed from code with python setup.py install

Version information

• OS: macOS catalina 10.15.7
• Python version: 3.9.2 and 3.8.8
• scikit-fda version: stable master (0.5) and develop
• gcc and g++ version: 12.0.0

I think this is probably a bug in the fdasrsf package. @jdtuck can you take a look at it?

[jdtuck]

I will take a look. Interesting as this has not shown up on any of the mac integration testing of mine or for cobra forge.

[jdtuck]

How are you install python in mac? This has to do with the system python or homebrew python. The fix is to set os.environ['MACOSX_DEPLOYMENT_TARGET'] = '10.15' in the setup.py. I am will try to make the setup.py smarter for mac os x. I don't have a lot of testing on mac so will get it in the next release.

[jdtuck]

This has to do with what MACOSX_DEPLOYMENT_TARGET your python was compiled for.

[jdtuck]

Pushing change to pypi in about 30min

[pablomm]

@jdtuck You were right, the new version in PyPI solved the issue.
I could install the package with pip install fdasrsf==2.2.6 and after that pip install scikit-fda worked fine.

About my python installation, it's a hombrew python.

Thank you very much for your support, the issue can be closed for my part.

[vnmabus]

Closing then! Thank you, @jdtuck, for your support!
