I’m trying t compile a script using JuliaC.jl and julia version 1.12.3, and I’m getting this error:

After doing as told from the REPL, I get exactly the same error. This was working before as a script, so I don’t really get what’s the issue here.

[This is what I’m trying to compile](https://github.com/cecimerelo/BraveNewAlgorithm.jl/blob/main/examples/BBOB_sphere_with_baseline.jl) Any help will be appreciated.
