ADA and OS/2

[Johannes Bruns]

Who knows an implementation of ADA running under OS/2 ?
Please describe its main features in a few words.

Thanks to everone who can help me !

Re: ADA and OS/2

[Billy Yow 283-4009]

The only OS/2 version of Ada that I know of is the one by Alsys.  I
don't know very much about it (saw it in 1988) but it did not have any
binding to the presentation manager and was just a 16 bit version (OS/2
is also just 16 bits).  I don't know if they still sell it or not or
plan to upgrade to Version 2.0.  The version I saw was for verion 1.0 or
1.1 of OS/2.

You did not specify if you are interested in Ada 83 or Ada 95. Certainly
GNAT is the only OS/2 Ada 95 compiler, but if Ada 83 is of interest,
Alsys certainly had an OS/2 compiler at one point, and as far as I know,
this is still marketed. You should contact Thompson Software for details.

As I said, other than GNAT, I could not find any other Ada 95 (or 83) versions. 
Sadly, Alsys does not exist (as stated by Thompson Software) plus they don't
know if ActivAda works under OS/2....hence the questions.

Thomposon *is* Alsys, the old Alsys technology is still marketed by
Thompson. You are not interetsed in whe
Whether ActivAda works under OS/2 (it almost certainly does), you
want to know if they are still supporting their old OS/2 compiler
technology. This compiler was validated, so it is certainly
reasonably complete, although it is certainly Ada 83 and unlikely
to be updated to Ada 95 I would guess.

Can someone from Thompson clarify? I hope I got things right!

Re: Ada and OS/2

[Robert Dewar]

One thing that would be interesting is to know exactly what you are looking
for in an OS/2 Ada compiler. In what respect does GNAT not meet your
requirements?

Thompson Software Products (formerly Alsys) has an Ada83 compiler for OS/2.  
I don't know if it has been updated to support Ada95.  They can be reached 
at 619-457-2700 x244 or adainfo@thomsoft.com.

  The Personal ActivAda on my machine does not work under OS/2.
The binder fails (probably a DPMI problem?).

It appears to be Ada95.

Thanks, anyway.

Good point. GNAT is slow, bloated and lacks an integrated interface.  For most
of my projects, development is 99% of the time allocated, execution is only 1%, hence
a development system with a good interface is worth far more than a compiler
that produces fast code.

I contacted them in the past, and I was told that it was no longer a supported   
product (and I guess they don't sell it anymore, either).  They did point out the   
nice, new, Windows NT compiler<G>.

Unfortunately, they nolonger support this product, nor will they willing to sell
it to me, hence Aysis appears to be dead.

You may use gnat. I am using gnat-3.09 and it works fine. If you like
to do PM-programing, this is no real problem. There are OS/2
bindings available as well.

GNAT for OS/2 is a complete implementation of Ada 95, and is fully
supported by Ada Core Technologies. Send mail to sales@gnat.com for
details.

Well the high performance version is HPFS386, which is what I
use, and it seems to have far more effective caching
capabilities than competitive systems on Linux or NT.

The new file system in the latest versions of OS/2 is a
compeltely new journaling file system, which is supposed
to be still faster, but I have not yet tried this.

I must say that I find OS/2 to be an excellent platform for
Ada development, certainly far better than NT, I am not enough
of a Unix expert to fairly judge Linux as an alternative.

The one measurement I gave is an interesting one, which is
linking the whole of the GNAT compiler (i.e. gnat1). This
used to take about 50 seconds on my note book using 286 HPFS,
and that seems comparable (given the speed of my machine)
with what you see on NT or Linux, but using 386 HPFS, the
link takes about 7 seconds, apparently because of the very
effective caching of object files. Fast linking is always
welcome :-)

Anyway, if you do want to give OS/2 a try, as I noted in a
previous post, we will soon have a version of 3.12p for OS/2.
It is indeed already prepared, and we are just doing some
basic sanity checks on it this weekend before posting it.

It's nice to know there are some fellow OS/2 Ada users out
there, and as I have said before, you can expect better
support for OS/2 GNAT in the future (we actually have two
OS/2 enthusiasts at Ada Core Technologies :-)

Are there any other options for an Ada 95 compiler for OS/2 besides
GNAT?

Thanks,
David

Re: Ada and OS/2

[David Dousette]

I was having a few troubles getting it set up at first, and I had a few
misconceptions regarding GNU development tools.  But I had assistance via
email and a closer read of the readme file, and I also had a lot of my
misconceptions cleared up, so now I can't wait till I get to the chapter in
my Ada book when it tells me I can touch the keyboard... ;^)

Thanks!

Re: Ada and OS/2

I have checked the Ada market since quite some years, but I do not know
of any other OS/2 Ada compiler.
Years ago I tried the (then) Alsys Personal Ada for Windows, but it did
not cooperate with WinOS2.
So it seems that Gnat is our only choice, but what is bad with it??

[John Merryweather Cooper]

Yes, it works quite well.  Cygwin and GNAT for WinDoze on the otherhand need
to be "kept at arms length" from each other.

Re: Ada and OS/2

[Christoph Seelhorst]

What seems another great thing to me is the fact that you can combine Gnat with
the other variations of emx, e.g. GCC , g++ and g77.  Well, I THINK it will
work, I have not really made in-depth testing there.  If anyone has experience
reports, I'd be glad to know.

Cheers,  Christoph

What exactly do you mean by that?

I use gnat and cygwin together - typically invoking
gnatmake from cygwin make or cygwin bash.
But I never use the gcc included with cygwin.

But not on OS/2.

Aha!  Some releases ago, both cygwin gcc and GNAT gcc used the same
registry entries to locate the gcc directories (where the actual C and
ada frontends reside).  That's the reason why you could only use only
one gcc installation (unless you had some small script which changed
the registry before you invoked one version or the other).  I don't
know if the situation has changed recently.
