ERROR: Failed building wheel for pycddlib-standalone for BurnMan 2.0

[Te-rex83]

When installing BurnMan from pip, this may fail depending on the python version up to the current 3.13 release.

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/ [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for pycddlib-standalone Failed to build pycddlib-standalone ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (pycddlib-standalone)

The user can go to the Microsoft website and download the online installer for MS Visual C++ 14, but may still be confused what components to download and install. The download is not small either, over 5 GB for a C++ compiler to build wheels for pycddlib.

I'm not sure how to avoid pycddlib, but it seems to be a requirement (i.e. not optional) to install BurnMan.

It would be best to make this package optional again, and when it is really needed, give a warning.

• Thanks for reporting this. Can you confirm that this is a problem only with python 3.13?
• If so, it might be fixed when pycddlib and pycddlib-standalone 3.0.1 are released: Prepare release 3.0.1. mcmtroffaes/pycddlib#75

• The problem exists with all versions of python 3.9 and greater.
• The problem does not exist for version 3.8 and lower because an older version of Burnman is installed...(presumably)
• Note that I can install pycddlib with pip for all versions of python, however the standalone version requires building wheels, which cannot be done without the development tools from Visual C++.

Ok, I think the pycddlib maintainer has already published a fix for the full pycddlib (https://pypi.org/project/pycddlib/), and he will probably push the same fix for pycddlib-standalone soon.

I opened an issue here: mcmtroffaes/pycddlib-standalone#1
