Re: Ada Compilers

["bklungle" <bklungle@ix.netcom.com>]

I can give you our current experiences. Yours may vary based on usage.

We are using Verdix Ada 83 on AIX (RS6k), Green Hills Ada 83 on AIX (RS6k)
cross targeted to the Rad-Hard RS6k with VxWorks, Green Hills Ada 83 on
Sparc/Solaris self targeted for debugging prior to using the cross compiler,
GNAT Ada95 on Dual P6/180 running Linux, GNAT Ada95 on IRIX 5.3 SGI Indigo2.
Another company we subcontract to is using Rational Apex C++ on SGI Indigo2.
Overall, the majority of the programmers prefer the GNAT Ada 95. If you go
this route, definitely grab ACT support. They have some excellent extended
tools and VERY knowledgable people who are willing to help, not like some
who take your money and return nothing.
To date, Rational Apex C++ is having trouble for as yet unknown reasons.
Again, experiences vary.

cheers...bob
