Dear all
After compiling and installing FreeFem I found that density plots are not shown, while the mesh plots are fine. The FreeFem warning is
`Plot:: Sorry no ps version for this type of plot 11`
The system is Ubuntu 20.04.
I’ve installed `freeglut3` from Ubuntu repository, though `which gglut` returns binary from FreeFem installation library.
Here is the end of `./reconfigure` prompt
```auto

```
Have no idea how to fix it, please, help!

As usual: no script to reproduce the warning/error =\> almost impossible to help you out.

Sorry, I withdraw the question. It’s my error. While making debug script I’ve found out that the warning was related to the `ColorScheme=2` option in the plot function. And after another recompile all the plots are shown.
