In fact SIMM installs fine in Scilab 2024.0.0 (by on-the-fly compilation) **but you have to install coselica before** , as the dependency of SIMM upon coselica does not seem to be set in the metadata of the package.

However, after satisfying this, there is a problem when SIMM loads:

```auto
atomsLoad : Une erreur est survenue au cours du chargement de 'SIMM-0.6.2':
	exec: error on line #172: "Variable non définie : cos_utils_lib"

```
