However, now I’m getting an error message which I’m not sure how to

The GNAT warnings switches -gnatw.d -gnatwaBCeJL include -gnatwe, which means "treat warnings as errors".

If you look at the top of build.sh it says

#    build.sh <other gprbuild options>

#    e.g. 'build.sh -j0' : use all available processors to compile

#         'build.sh -wn' : treat warnings as warnings.

#         'build.sh -vh' : Verbose output (high verbosity)

and I’d use -wn as well as -j0 (I probably wouldn’t use -vh, can be a bit overwhelming).
