cc @amontoison I guess we need to rebuild `libknitro.jl` for v14? I assume the sigabrts mean that we're calling some part of the C API wrong:

These segfaults are in the middle of `KN_solve`, and they are for a linear problem. I think this might be a bug in KNITRO? We're not doing anything to trigger...

This is known and it is a pretty unavoidable consequence of how Julia's dispatch currently works. We'll fix ambiguity errors on a case-by-case basis with working examples that demonstrate a...

It seems like CPLEX 22.1.1 know supports M1: https://stackoverflow.com/questions/74892000/cplex-22-1-on-macbook-with-m1-architecture. If anyone can confirm, I'll close this issue.

Here's some official documentation that confirms CPLEX 22.1.1. can run on M1: https://community.ibm.com/community/user/ai-datascience/discussion/cplex-optimization-studio-2211-is-available. If anyone still encounters issues, make sure you have installed a download containing `.arm64` in the filename.

A few questions that can help diagnose this: * What is `versioninfo()` * What is `import Pkg; Pkg.status("CPLEX")` * What files are in the `arm64_osx` directory?

> OS: macOS (x86_64-apple-darwin21.4.0) You've installed the x86 (Rosetta) build of Julia. If you install x86 Julia, you must also install x86 versions of dependencies. So either: 1. Install the...

Closing for the same reason as https://github.com/jump-dev/Gurobi.jl/issues/354#issuecomment-2111399252

For the columns, you need to use a 0-indexed `Cint`. ```julia import MathOptInterface as MOI import Gurobi model = Gurobi.Optimizer() x, sin_x = MOI.add_variables(model, 2) Gurobi.GRBaddgenconstrSin( model, "sin_constr", Cint(Gurobi.column(model, x)...

I've added a minimal amount of documentation here: https://github.com/jump-dev/Gurobi.jl/pull/526
