Hi,

I am running Pop OS on Linux 22.04 and I installed FreeFem++ with

```auto
sudo apt-get install freefem++

```

and then tried to run the official cantilever beam example from [here](https://doc.freefem.org/models/elasticity.html). However, some dependencies are not found because I get an error

```nohighlight
 Load: lg_fem lg_mesh lg_mesh3 eigenvalue 
    1 : include "cube.idp" Error opening file cube.idp in: 
  -- try :"cube.idp"

```

Is there anything else I should do?

I think this related to setting the `freefrem++.pref` file - check the documentation for more info.

The file cube.idp is in directory

ff-4.11/lib/ff++/4.11/
