Installation Problem

[Sharif432]

During the installation "pip installs PySPH", I received an error.

I'm using python 3.9.13 and MSVC 2022

Output:

pysph/base/cell_indexing_nnps.cpp(3280): error C2169: 'log2': intrinsic function, cannot be defined
pysph/base/cell_indexing_nnps.cpp(4017): warning C4244: '=': conversion from 'Py_ssize_t' to 'int', possible loss of data

Can you provide more details on this please? Is this from a windows powershell? Or is this from WSL?
This error is unusual, log2 is only defined within a suitable guard specific to MSVC. Our tests run every week without error on windows as you can see here it ran 3 days ago and the version of MSVC seems the same as yours: https://github.com/pypr/pysph/actions/runs/4149657878/jobs/7178770542

I am not sure it will help but you can also try to install from the latest version of pysph on github either using: pip install https://github.com/pypr/pysph/zipball/master or via the usual git clone and other commands mentioned in the documentation.
