Get motile on conda-forge

[cmalinmayor]

@tlambert03 @constantinpape mentioned that the Gurobi dependency is not necessary for his work and it is limiting to have to install it with the extra conda channels. I know we discussed looking into not needing to install Gurobi - can you remind me how hard this would be to implement logistically?

[tlambert03]

It needs a change at the c level in ilpy. It's conceptually straightforward, but not trivial.

funkelab/ilpy#14

Is it now possible to install motile from conda forge? I am asking because this issue was closed, but the installation instructions still specify installation via the funkey and gurobi channels.

[tlambert03]

Hi @constantinpape,
Apologies, it's not on conda forge... it still represents a significant amount of work that I don't currently have time for. I'll reopen this.

[constantinpape]

Thanks for letting me know @tlambert03 and thanks for reopening the issue.

I understand that this is quite some work, just wanted to express that there is still interest from our side in this.
(Without a conda-forge installation it is quite cumbersome to integrate this as dependency with other conda packages, since conda-forge builds cannot refer to external channels.)

[tlambert03]

Yeah I know, sorry. It's precisely because they can't refer to other channels that makes this hard, because the c code ilpy was originally written in such a way that requires the gurobi library to be present (even if you don't intend to use it). So, putting this on conda forge requires rewriting ilpy to dynamically load libraries rather than link them upfront. It's doable, but takes some surgery on ilpy

But, interest noted! Thanks :)
