Package for spack.io

[alexrobomind]

Dear colleagues,

as part of my recent stabs at installing VMEC on my own Linux VM and on the FZJ supercomputer, I have created a STELLOPT package for the Spack HPC package manager (https://spack.io) to automate dependency management and the build process (including potential site adaptations). Currently it builds libSTELLOPT and VMEC, but I am more than happy to add additional variants for other codes as well.

I would like to publish this package to the main spack package repository, but since I am not directly affiliated with the code I wanted to check out whether this would be fine with everyone.

Best regards from Jülich,

Alex.

I am fine with it and this sounds great! The code is open-sourced, so I assume all useful contributions are welcome. I don't think this will break the MIT license that STELLOPT currently uses.

The package itself does not contain the source code, just instructions to the package manager on how to fetch, catch, and build from the source.

Alex,
Sorry this took so long to get back to. Is your Spack package available somewhere?
Cheers,
Sam

Hi Sam,

there is a "half-done" version sitting in here: https://jugit.fz-juelich.de/a.knieps/iek4-spack-packages

If I remember correctly it did the VMEC build fine, but I never got it to a point where I found it truly worth upstreaming (with proper MPI variants, variants to select individual codes, etc.). I had real difficulties gauging which features would truly be worth including, so if you have some pointers on that I still think it can be made useful.

Best regards,
Alex.

EDIT: When browsing this repository, please note that most of these packages are SEVERELY out of date when it comes to versioning, as I have in the recent years worked on a lot of monorepository builds which do better with air-gaps and Windows/Linux compatibility.

It seems like it would be pretty simple to bring this over into the STELLOPT package via adding just a couple of file. Maybe in the /SHARE/ directory.
