Re: [Paparazzi-devel] compile error

[Gautier Hattenberger]

Hello,

The function String.lowercase_ascii is rather "recent" and is probably 
not available with the OCaml version from Ubuntu 16.04.

You either need to use an older version of Paparazzi or a more recent 
version of Ubuntu (better 22.04, 24.04 should work as well but some 
dependencies have to be installed by hand for now).
