installation with pip fails

[rpoteau]

Hello
the installation fails. The final message says

  subprocess.CalledProcessError: Command '['cmake', '--build', '.', '--config', 'Release', '--', '-j2']' returned non-zero exit status 2.
  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pybinding
Running setup.py clean for pybinding
Failed to build pybinding
ERROR: Could not build wheels for pybinding, which is required to install pyproject.toml-based projects

Thank you for your help

Hi Romuald
this error is a generic error that the compilation on your system didn't work.
Can you specify the operating system and python version?
If pip cannot find a pre compiled version, it will try to compile it. This message just says that it didn't work.
Now you have two options:

1. use the new (development) version that has a lot of pre compiled versions by pip install -i https://test.pypi.org/simple/ pybinding
2. provide a more detailed error message so that we can know what didn't work

I would only say to compile from source when you're doing quite intensive calculations, where you're running pybinding for hours on a cluster.
The first option is perfect for just configuring a system and doing smaller-scale caltulations.
Anyway, when you really want to have a fast and preformant calculation, you'll need to have a look at the quantum-KITE project.
Let me know if the first option worked out for you.
Best
Bert

Hi Bert thanks for this very fast answer :-) I am working under linux, my OS is the opensuse rolling release, aka Tumbleweed. pip --version returns: pip 23.2.1 from /usr/lib/python3.11/site-packages/pip (python 3.11) and please find enclosed the whole error output Best Romuald Le 11/11/2023 à 21:02, Bert Jorissen a écrit : Hi Romuald this error is a generic error that the compilation on your system didn't work.

Did the installation of the new version work?
Otherwise, you'll have to add the pip install pybinding --verbose option for the full logs.
Your mails will be displayed on the public GitHub automatically, and I couldn't see your attachment.
