The GNAT compiler

GNAT is the Ada 95 version of the multi-language compiler gcc from the Free Software Foundation. It now incorporates almost all new features of Ada 2005.

It is "free" software, which means you can get it freely from various FTP sites (Main site: GnuAda). All sources are available, as well as prepared installation for various machines (PC/Dos/OS2/Win95-NT/Linux, Silicon Graphics, Dec-Alpha, IBM-RS6000, HP-PA, etc.).  For MacIntosh, see MacAda.

It is a full implementation of Ada 95, including all annexes. It is validated on several targets.

NEW: JGNAT is now issued, a version of GNAT targetted to the Java machine!

NEW! Martin Carlisle has ported JGNAT to the .NET environment. It is now officially part of Visual-Studio.NET. For more info, go to the A# website...

NEW: A certifiable kernel for critical real-time systems, that conforms to the "Ravenscar profile", is now (freely) available. Information available on the OpenRavenscar site.

And more! There is now a port to RTLinux., and a (still incomplete) port to AVR, the first Ada compiler targetted to an 8 bits microprocessor!

The Aonix compiler

Aonix offers a free evaluation version of its compiler for Windows 95. There are some limitations compared to the commercial version, but it features a user interface that compares nicely with all Visual-XXX of You-Know-Who. And it allows, even in the free version, to make applets as easily as with Java!

It can be downloaded, but, considering its volume (70 Mb), it is better to get it from a CD. It can be obtained for free by simply asking Aonix, or from the Ada CD-Rom.
