Problem with emacs ada-mode-7.1.4

[Paul Onions <ponions37@gmail.com>]

Hello All,

Not sure if this is the right place to post this, but I have a problem compiling the Ada code after installing ada-mode 7.1.4 as a package in Gnu Emacs 27.2.

Specifically, when I cd into ~/.emacs.d/elpa/ada-mode-7.1.4/ and issue the command ./build.sh I get the following:-

...

I'm using GCC 11.1.0 from the download at https://github.com/simonjwright/building-gcc-macos-native, on macOS Big Sur.

Any help appreciated.  Thanks,
Paul
