I'm sorry, but I never got the first emails about this bug. There seems
to be an issue with sending email from the bug server to my mail server.
It's possible a spam filter ate them.

Since you are using ada-mode, the assumption is you are used to
compiling Ada code, so this should not be a burden.

This indicates a problem with your Ada compiler installation.
'directories.gpr' is not from ada-mode.

If you use the Community release of GNAT from
https://www.adacore.com/community, build.sh runs cleanly.

They are all available at
https://download.savannah.nongnu.org/releases/ada-mode/, back to
ada-mode 5.1.9 in 2016.

Once you get the code compiled, there are many benefits to the latest
version; support for Ada 2012 (and 2020 in the next release), more
consistent indentation, integration with package.el.

I deleted the old ada-mode to force people to try the new one,
and also to avoid maintenance requests on the old code. I have no
objection to making the old code available in lisp/obsolete, so it is
clear it is no longer supported.
