Having problems with compile.cmd

[adgelt]

I'm getting this issue of not finding the python311.dll in the folder but upon checking there is existing file. What could be the problem?

Looking for python311.dll
INFO: Building import library (arch=AMD64): "C:\Users\Gelo\libs\libpython311.a" (from C:\Users\Gelo\python311.dll)
error: [WinError 2] The system cannot find the file specified

At present, we haven't built against Python 3.11 on Windows environment, so unsure what may be the cause. If you could provide additional info such as operating system, python version, what package manager you're using (e.g. conda, pip, virtualenv), we may be able to assist.

Hello, I'm using Windows 11 as OS, and tried installing the code using pip. What could be the problem?

This still uses an older build method for the FORTRAN extension packages (wind.windmodels, etc.), which is the likely culprit of the error you're seeing. There is a bit of additional complexity in the existing setup.py script that we can do away with (the py2exe components haven't been used in a long time) - I'll take a look at what's needed to update to the newer build systems:

EDIT: Also worth pointing out that you don't need to compile these extensions to run the model. The FORTRAN versions enable a speedup over the pure python implementations (except for akima) which are included.

What versions of Python and other extension packages should I be using for the compile.cmd to work?

I've made an attempt to build on Windows x86-64 using MinGW-w64, Python 3.11, and can't get it to build, having tried a number of strategies. Some investigation suggested that there's an issue with MinGW-w64 interacting with the python311.dll.

Rolling back to Python 3.10 is one suggested workaround. In the meantime, I'll continue to work on the package build for the next updates.
