# Specpart
This is used by the wavespectra packages (both wavespectra/wavespectra and metocean/wavespectra).
This repository is used to create pre-build binary wheels for windows.<br>
Linux and macos are open to contributions.
## Creation
Getting this to work was a bit of a trial-and-error. The following problems were encountered:
- not compiling, fixed by removing some of the statements from the generated .f90 file
- not working on the target machine due to missing .dll files (Importing created package fails with ImportError: DLL load failed)
The following steps were taken with help from the community:
- generated wrapper using f2py and specpart.f90 (not using pre-exising .pyf file) file
```commandline
python -m numpy.f2py specpart.f90 -m specpart
```
- manually edited the generated .f90 wrapper file, removing sections:
```
use specpart, only : ptsort
use specpart, only : ptnghb
use specpart, only : pt_fld
```
- created meson build file: [meson.build](https://github.com/RubendeBruin/specpart/blob/main/meson.build):
- set meson-python as build backend: [pyproject.toml](https://github.com/RubendeBruin/specpart/blob/main/pyproject.toml)
- used Github Actions to perform the actual build on windows: [actions](https://github.com/RubendeBruin/specpart/blob/main/.github/workflows/main.yml)
Attention points:
- As the target machine is not the same as the build machine, the dlls need to be bundeled: see [discussion](https://github.com/mesonbuild/meson-python/discussions/595#discussioncomment-8704971)
- use delvewheel to inspect and repair created wheels. This includes all the required .dll files in the wheel
- delvewheel stores the repaired wheel in the /wheelhouse folder, this is uploaded as artifact.
- download the wheel and install it using pip
Checks:
- Importing works,
- Required functions are available:
```
Python 3.11.3 (tags/v3.11.3:f3909b8, Apr 4 2023, 23:49:59) [MSC v.1934 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

## Open questions
- Why is devewheel required when we do static linking?
- Why does devwheel not accept wildcards?
