Hi AdaCrypt

You did not mention what you OS is (or how your software is licensed). Their
are a few open source/community editions available, That may suit you, these
being.

- AdaCore's GNAT 2018 community edition (cant be used in commercial apps.)
(this supports windows x86/x64 , Linux x86/x64 (and I believe Mac?)

- MSYS2 (this supports windows x64, although if you are feeling keen, then
you could build a windows x86 target if needed. I believe that this can be used
in a commercial product ?)

- Simon Wright has a GNAT FSF MacOS build, same licensing as MSYS2 applies.

WRT John Barnes publications (ie Rational's). I find them very good at
describing the new features in each iteration/version of Ada.

You don't need to get the compiler on CD-Rom, just download from the following

- AdaCore's community edition is at https://www.adacore.com/download
- Msys2 - First install MSYS2 and then use pacman to install gnat
- macOS - https://sourceforge.net/projects/gnuada/files/GNAT_GCC%20Mac%20OS%20X/9.1.0/
