Create a package KNITRO_jll.jl ?

[amontoison]

@odow
I am wondering if we should not try to do a KNITRO_jll.jl like you did with Xpress_jll.jl and GUROBI_jll.jl.
What do you think?

This requires permission from Artelys for the binaries to be publicly available (e.g., pip install knitro), which I don't believe is the case?

[amontoison]

I quickly discuss about that with an employee of Artelys during ISMP.
I will contact them next week.

In the worst case they can do like HSL and have a dummy version of the JLL.
It will allow Artelys to not provide the official KNITRO_jll.jl with precompiled binaries to everyone if it's the issue.

Hi all,

I would like this.
We'll discuss about it and get back to you in September.

So far we've avoided it but this is currently under consideration, although there are a few things we need to figure out.

Thanks @mgabay.

The precedent for this is:

• https://github.com/jump-dev/Gurobi_jll.jl
• https://github.com/jump-dev/Xpress_jll.jl

They both pull from the official anaconda sources, e.g., https://anaconda.org/Gurobi/gurobi, so something similar would be our ideal. I guess my suggestion is "don't treat this as a Julia issue. Treat it as a Python packaging problem, and we can re-use that solution."

@mgabay
Any update from Artelys?
I'm available for a meeting if that could help facilitate the discussion.

Hi @amontoison ,

We plan to do it for Python so that you can then setup something similar to other solvers.
However, we have yet to figure out a few details and put it in the roadmap.
This is probably going to be for Q1 2025 but it is not scheduled yet.

Seems like progress is being made: Pyomo/pyomo#3478

We also need the shared libraries in Julia.

[odow]

Yes, but we'll just rip from the Python ones once they're published. No need to duplicate work.

Hi,
Yes we are making progress, the Python package including the shared libraries will be released along with the next Knitro release, scheduled for early June.
