does not allow current version of MKL_jll

[JeffreySarnoff]

In almost new directory (added Ipopt first):

pkg> add SCS
...
pkg> status --outdated -m
⌅ [856f044c] MKL_jll v2022.2.0+0 (<v2023.1.0+0): SCS_MKL_jll

[odow]

Blocked by JuliaPackaging/Yggdrasil#6766. We have to be very careful with this one. It's a known issue.

[JeffreySarnoff]

Thank you for the informative, very prompt responses.

very prompt responses

My secret is that it's 2pm in New Zealand 😄

@odow I don't quite understand why this is still happening:

Releasing that version didn't update the compat in the registry:
https://github.com/JuliaRegistries/General/blob/f6a8f2f6c67541c797cd0bdfd8d03b65d67dc3e1/jll/S/SCS_MKL_jll/Compat.toml#L8-L9

I guess we did need to bump the version

[kalmarek]

oh well;

After thinking maybe what Mose suggested is a better option:

• make SCS_MKL_jll depends on MKL_jll unconditionally
• use Require based on the presence of SCS_MKL_jll rather than MKL_jll

Then users workflow would look like

Pkg.add("SCS")
Pkg.add("SCS_MKL_jll")
import SCS_MKL_jll
using SCS

This way it's the role of SCS_MKL_jll to take care of its deps, not of the user. What do you think?

[odow]

This will require us to release SCS 2.0, but that's okay.

[odow]

We could also just edit the general registry

[odow]

See JuliaPackaging/Yggdrasil#7665

We'd change Requires to SCS_GPU_jll and SCS_MKL_jll, and we'd drop support for 3.2.3 and earlier. This likely requires a 2.0 release of SCS, but I'm okay with that.
