Crash on windows

[RobbieKiwi]

The Python process crashes when trying to import highspy on Windows Server 2019. I think due to a missing .dll or something.

This occurs on with version 1.14.0. It does not occur with the previous version 1.13.1.

I tested with Linux, and Windows 11 and it works fine so I guess it just affects the old windows server version.

Reproducible example:

Windows Server 2019 Standard
version: 1809
os: 17763
Python 3.12

import highspy

Another one for you @galabovaa, thanks

I made some changes to CMake which may resolve the issue here:

https://github.com/ERGO-Code/HiGHS/tree/windows-server-2019

We don't really have access to a Windows server, would it be possible for you to check whether the updated code from the branch above resolves the issue?

Hi, thanks for having a look at it, I tried on that branch but I get the same issue, every time I import from highs the python process crashes

We discussed this on the HiGHS developer call.

Windows Server 2019 reached mainstream EOL in January 2024: https://learn.microsoft.com/en-us/lifecycle/products/windows-server-2019

There's something to fix, but it might be hard for @galabovaa to get access to a machine.
