Create a package KNITRO_jll.jl ? #302

@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?

odow commented 3 months ago

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 commented 3 months ago

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:

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.

mgabay commented 3 weeks ago

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.
