@bryanwweber oops - forgot that was turned on at work - meant to get back to this anyway at home, so here is the corrected commit

Looks like this doesn't actually fix the problem and I'm not sure why (I did a scons build/test/install and I still get the same bug - any ideas as to what I did wrong (I definitely don't understand 100% what's going on here in any case)

[bryanwweber]

@mefuller can you open up the generated solution.py in the build folder? That'll show you the actual code being run. I also edited my comment above with a suggestion for the implementation

@bryanwweber looks like the CI / .NET failures are due to a 404 pulling down dependencies - is there an easy way to re-trigger these?

[bryanwweber]

@mefuller I just restarted them

[speth]

I think the failure of the .NET on ubuntu-22.04 run is because we're missing a sudo apt update before the sudo apt install ... command in that workflow (though I don't really understand the circumstances under which older package versions are removed from the Ubuntu repositories).

The other errors with the .NET interface are already fixed in the main branch (see commit aee309220), and can be resolved by rebasing.

[mefuller]

@bryanwweber the failures in CI seem to all be on .NET (with which I am not at all familiar) - any idea what might be the cause?

[bryanwweber]

I'm not sure, I think some foxes are on main if you haven't rebased in a bit. Maybe @speth can help 😟

[speth]

The solution to both distinct errors is in my previous comment.

[mefuller]

Sorry7 about glossing over that @speth - rebased and rerunning

[bryanwweber]

Thanks @mefuller , the code looks good, I just haven't had a chance to pull it down and try it out. I'll try to do that soon!
