GPS, or GNAT Programming Studio, is an IDE (Integrated Development
Environment). In other words, an integrated editing environment that
has a number of well-integrated features and capabilities.
GNAT Pro is an Ada Development Environment, and consists of a suite of
tools, including compiler, utilities, libraries, _and_ GPS.
GNAT Pro will be the best-integrated and functional of GNAT-based
development environments, mainly because AdaCore is being paid to
support and maintain it. For paying customers, AdaCore will also
respond to any issues that do arise in your use of the product.
Free distributions of GNAT-based development environments do not have
this level of support, although there is conscientious and active
support of various distributions by committed individuals. (AdaCore
itself does also distribute GNAT GPL 2005 for Free Software development,
but maintains it only on an "as time permits" basis.)
The components in these other non-AdaCore distributions are somewhat at
the mercy of AdaCore's release of public sources. So it is fairly
likely that a free distribution will not have all of the latest and
greatest sources. And while there's nothing to stop individuals from
making their own source code updates, there's usually a reluctance to
get out in front of AdaCore, as that runs the risk of forking the code base.
For the development of truly safety critical software, one would be
ill-advised to attempt to go it alone with an unsupported development
environment. Given that the costs of development, integration, testing,
and certification of a safety critical system are going to far outweigh
the cost of the development tools, it would be foolish to attempt to
save a few thousand dollars by working without vendor support.
