ERROR: Could not build wheels for sphericart, which is required to install pyproject.toml-based projects

[weberscode]

Hi all,

i did the following and could not install it to my conda environment.

1. Open python terminal of my environment with python3.9
2. Type "git clone https://github.com/lab-cosmo/sphericart"
3. Type "cd .\sphericart"
4. Type "pip install ."

Then i get the following error:
Building wheel for sphericart (pyproject.toml) did not run successfully.
│ exit code: 1

What am i doing wrong? I have a standard windows computer.

kr Simon

Sphericart does not currently support windows: #27.

Just to be sure you are hitting the issue I think you are, could you share here the full build log with pip install --verbose .?

---

If you are able to use it, Windows Subsystem for Linux (WSL) gives you a full Linux environment inside windows, accessible without having to reboot, and could be a solution while we work on native windows support.

pip install --verbose .

Thanks for sharing this! It is actually working much better than I though and almost managing to build the code. The error concerns OpenMP: https://learn.microsoft.com/en-us/cpp/error-messages/compiler-errors-2/compiler-error-c3016, which should be relatively simple to fix.

EDIT: seems that the core of the issue is that MSVC only supports OpenMP 2.0 (https://stackoverflow.com/a/2822064/4692076) and we are using features from more recent versions of the standard.

As mentioned in #129, an experimental version which builds correctly on Windows is available in the build-windows branch
