ADA for OS/2

ADA for OS/2

[John Poltorak]

GNAT 3.13p includes OS/2 patches but building an OS/2 binary is a
non-trivial task.

Is there any possibility that I can I get hold of an OS/2 binary from
anywhere?

The possibility exists.

I have GNAT on a CD from 1995 that I plan to use to build an OS/2 
version. If that goes well then I will d/l a newer cut of GNAT and 
give that a shot. This will take a couple of weeks to organize, as I 
am a little busy on other things just now.

I got as far as applying the OS/2 patches to the source code but apparently
you need to
have 3.12 installed as 3.13 is built on top of that. A few people are
trying to build it and we are
currently discussing progress on the os2-unix mailing list and you are
welcome to join in, which

OS/2 patches are included in the source, so I'm sure it runs on OS/2,
it's that there is no compiled version available for 3.13p AFAIK.

Don't make presumptions please Ted! No one said Robert Dewar had
stopped using OS/2. I still run OS/2, and I still run GNAT on it.
However, my build is not releasable, it is tied into my entire
environment, and since we have abandoned the OS/2 product, we are
no longer making releasable builds on this operating system (and
that includes both the GNAT Professional version and the public
version).

I do welcome the recently announced contribution of a 3.13p build, and
we hope that similar efforts will produce public binaries on various
targets. We will be happy to assist in making these contributed ports
available on the NYU site.

Linux -- I am beginning to miss some of the nice GNAT tools that are
not available on OS/2 -- anyone know of an implementation of EPM on
Linux :-)

Just a minor nit here, but I don't believe the "t" in "tmoran" stands for "Ted".

have a look at hobbes or leo - there you should find at least gnat 3.12 precompiled for os/2 using emx-environment. or try www.os2.org iirc it has a search engine for software.

I installed 3.12 yesterday, but find the instructions for building 3.13p difficult to follow.

From README.BUILD:-

This installation starts from the sources of GCC 2.8.1

  -- Apply patches (gcc-281.dif) from the src directory.

Do I really need to get hold of the source for gcc 2.8.1, just to be able to build 3.13p ?

If so, do I just run:-  ?

patch -p0 <gcc-281.dif

Yes. 

Why is this surprising? You are building a compiler from sources; part
of the sources for that compiler is gcc 2.8.1.

Getting hold of the source for gcc 2.8.1 is no harder than getting
hold of the source for gnat 3.13p.

Perhaps you are implying that the source distribution for gnat 3.13p
should include the source distribution of gcc 2.8.1. That might be
convenient for you, but it is common practice to simply reference an
independent source distribution, when that imposes no significant
burden on the user.

> If so, do I just run:- ?
>

Yes. It would be better if this specific instruction were in the
README file, but a quick read of patch --help makes it pretty clear.
In general, it is assumed people installing from source can figure out
how to use the required tools.

In general, that is true, but in the case of GNAT it seems that ACT
is only releasing binaries for certain platforms these days, which
means installation from source becomes more commonplace and is not
at all based on expertise (especially in view of ACT's statement
that they feel the public releases should be for student use).

Most people will not be able to install GNAT from sources, since it
does indeed assume GCC expertise. It is definitely true that ACT is
not building public binaries for most platforms these days (our
current intention is to build binaries for GNU/Linux/x86 and for NT).
We expect that other public binaries wlil be built, distributed
and mirrored, by those who do know how, as happens for other GNU software.

This is not happening for OS/2 however. There are a number of us 
interested in getting this going and are willing to try but we need 
help. If for no other reason than maintaining and extending the scope 
of Ada to another area of computing. Isn't that what most of the 
discussions in this news group have been about over the last 5 years 
that I have followed  C.L.A? [other than a few java vs Ada vs Eiffel 
wars and the Rt. Rev. Colin James III entertainment from years past. 
What ever happened to the kook?]


Back to the topic at hand. By help, I am asking for some mentoring for
us, walk us through the process, do not assume what we know or don't 
know, in return we will document the method and steps and keep the 
knowledge available for orthers. As it is now when Robert Dewar and a 
few select others decide that Ada/2 is a waste of their time the skill
set is lost! I don't pretend to be able to write intricate code, I 
don't pretend to be a 'code rocket doctor', I am sincere about getting
this done for OS/2 though. I know there at least three of us currently
interested in building the beast, what do you say? A knowledge tranfer
is what we are asking for.

Probably the best thing to do would be to just start slogging through the
process, and then appeal for help at the appropriate places when/if you get
stuck.

If you need help getting started, I'd first download the sources and read
through any instructions there. Then the next best thing to do would probably be
to appeal to the folks on the Gnatlist at
http://lyris.seas.gwu.edu/cgi-bin/lyris.pl?enter=gnatlist&text_mode=0 . There
seem to be several people there who regularly build gnat from sources.

I haven't personally done this before. However, I have compiled gcc from sources
before (many years ago on SunOS). It did take me about 10 hours of work (mostly
due to slow compile times), but it really wasn't too horribly difficult. Don't
let anyone scare you off by throwing that in your face.

There is an immediate problem when attempting to follow an instruction like:-

  -- Apply patches (gcc-281.dif) from the src directory

... does this simply mean using the source straight from GNU, ie. :-

ftp://ftp.gnu.org/pub/gnu/gcc/gcc-2.8.1.tar.gz


or do I need to find and apply some EMX patches first to incorporate OS/2
enhancements?

And if so, which patches?

Any hints/tips, much appreciated...

Once again, I strongly suggest that you go through the process of
bootstrapping the OS/2 EMX version of GNU C, and don't even think
about porting GNAT till you have completed that excercise successfully.
If you have not already, I would recommend reading the gcc manual
cover to cover.

Here is a question directly related to a frustration I have been 
having:

there are a vast number of GNU/Unix ports of utilities for building  
software. These come with various bugs and limitations. What are the 
exact versions used to build GNAT? As an example there are several 
MAKES floating around and it is a royal pain to find one that will 
apply the patch file.

I have posted to GNATList in the past. There is little expertise there
about OS/2 and GNAT.

The one distributed with Gnat-NT reports being "GNU Make version 3.77". However,
I doubt it would hurt anything to go a rev or two back.

The FSF once released a critically broken make (IIRC, it was version
3.76), but if you don't use this one, the make version probably
doesn't matter much indeed.

Exactly where have you got stuck?

Applying patches (gcc-281.dif) from the src directory? Or are you further along than
that?

Do you need to apply any specific EMX patches?

Currently the situation is a bit warped because ACT essentially controls the
Gnat baseline. Of course ACT doesn't *have* to do anything. But on the other
hand, folks have been trained to expect a lot of from GNU software maintainers.

I think that once Gnat is in the GCC baseline (RSN, right?), its perfectly
reasonable to expect the community to build its own binaries for *all*
platforms, as well as to coordinate releases, etc. If ACT feels its in their
best interests to contribute to that effort, then great. But they are a
*company* and its about time we quit expecting them to do tons of stuff for us
for free, just because we'd like it.

True, but since the OS/2 code is still in the baseline presumably it 
is tested and the results of the tests would include an OS/2 binary
which would in turn have to be tested.
If that is true, why not release it, or is the OS/2 code not tested
anymore?
If it is not tested, what does that mean for the quality of any private
builds?

As an aside, it seems that my other preferred OS, OpenVMS, is suffering
the same fate.
All that I could find on ftp://cs.nyu.edu was 3.11p and 3.12p.

BTW, do they just mirror ACT or do they produce their own binaries?

This sounds like a moot point since no one apart, from the GNAT developers, appears
to be able to build an OS/2 version...

ACT no longer supports the OS/2 version of GNAT, since there was
insufficient commercial demand (we had one customer, who is in the
process of switching to windows).

> private builds?

Probably they should be in fairly reasonable shape, since I still
build on OS/2 for development purposes, though we don't do any
formal testing of the OS/2 version at this stage.

The OpenVMS version of GNAT Professional is fully supported, and we
have a number of supported customers for this platform. We are not
planning on releasing public binaries, since this is no longer a

cs.nyu.edu has binaries of the public versions, some are built by ACT,
others are built by other volunteers.

Thank you for your reply and sorry I took so long to reply.

Anyway in the meantime I have built GNAT 3.13p and GCC on OS/2
and have a couple of questions.

Firstly, when building an archive of the resultant files to
form a possible distribution I noticed that gnatelim and
gnatstub are missing from 3.13 although they were in the 3.12
archive. Are these no longer required or are they in another
source archive? 

The second point concerns testing. Is there an accepted standard
test suite anywhere that I can download?
I've had a look around ACT and AdaPower, but could not find
anything.

Thanks,
Dave

Wonderful! Would you be so kind as to post an the details of how you 
do this. I would like to learn how and archive them as well. That way 
we are never stuck in this position again. And, of course, when and 
where may we download a copy?

Yes, of course, but first I must confirm that it works correctly,
then I will make it available.

In essence, I only followed the instructions in README.BUILD, plus
a few minor tweaks to the makefiles.

In our experience, building GNAT is quite straightforward if 

a) you have reasonable experience with building gcc, and know the
basic structure of the makefiles (and are fully familiar with make),
i.e. just basic gcc build knowledge

b) you follow the instructions. It is amazing how often people get
into trouble because they think they know better than the instructions :-)

The tweaks to the makefiles are needed information. When you are ready
to release let me know as I want to try the build myself and would 
like to get some help for the process.

Well, here is the crux of the problem: I do not have the requisite 
experience which is why I am interested in getting the method down and
archiving it.

I am able, and willing, to follow instructions. But when those 
instructions rely on assumed knowledge they are of little use to the 
beginner. See above.

Indeed, we do not expect beginners to be able to necessarily succeed
in building GNAT from sources, since this is not a trivial task, but
good for you if you succeeded anyway!

I am still in the testing phase at the moment but, thinking positive and
looking to the future, will ACT continue to update the sources, makefiles
etc so that private OS/2 builds will still be possible?

I don't like the idea of multiple source distributions floating around and
also I don't have the time to be the OS/2 maintainer, although I am happy to
build them now and then so long as the time required does not escalate.

ACT no longer supports GNAT on OS/2, it is not one of our officially
supported platforms, so the source releases from ACT will probably
not update any OS/2 related information.

On the other hand, one would hope that someone will provide and
maintain the GCC 3.x GNAT sources for OS/2 at the gcc site. We are
still hoping to get this set of sources available soon.

Ok, fair enough. It is a business for ACT after all.
It is a pity though, that we will not be able to incorporate OS/2
changes into the common code base.

I will take a look when they are released and see if I can build an
OS/2 version, but I hope that someone else with more spare time will
be able to carry on in the future.

Oh, but you will! That's the point of having the sources at gnu.org,
contributions of this kind will be welcome. After all if 100% of the
changes are being done by ACT, there is no point in having the sources
at gnu.org, the whole point of putting them there is to take advantage
of volunteer efforts, since, as we see in the OS/2 case, ACT can't
manage to handle all possible ports, but we will be happy to
incorporate any OS/2 contributions.

Ok, thanks for clearing that up. I was a bit uncertain about the

Ada Core Technologies will provide the initial sources, and will likely
contribute many (but hopefully not all :-) of the continued improvements.

It really does seem unfair... If you use NT everything is on a plate. You
just download a binary archive and you can be happily using GNAT 3.13p
within a few minutes without requiring any knowledge of building
compilers. If you use OS/2, the same task is going to take several weeks
or months. I don't know anyone who has been successful building OS/2
binaries, which  kind of begs the question who is the OS/2 patch designed
for? I note the OS/2 patch is 8000 lines long which is twice as long as
all the other patches put together, and I think if someone is going to the
trouble of providing such complicated patches, their work will not be very
well appreciated if no one can make any use of it. Maybe providing a
simple build script is all that is necessary to make it work...

It is only right that software suppliers should have a lower 
expectation of the skills of Windows users: they have usually had the 
OS foisted on them when they are first "trying the water" in 
computing.

Not necessarily.

People like me, who have been programming for donkey's years and 
programming OS/2 for quite a few years within that period.

The term "build script" will cause many developers to shudder. The 
usual term is "makefile", but the exact nature of this is determined 
by the make utility one uses. I use DMAKE 4.0 for OS/2, and when I get
around to building GNAT that will be the maker I use, even if I have 
to coerce the makefile a bit. Even so, a makefile is not necessarily 
useful to an end-user; but if that end-user fancies himself as a 
programmer it *should* be enough.

Anyhow, watch the OS2PROG echo on Fidonet and see what turns up. I 
might also post an announcement here. The initial d/l site will be 
Pete Norloff's BBS, later Hobbes and Leo.

No, not really. By build script I'm talking  about all the processes involved in
building an app.

This is likely to include retrieving a tarball, unarchiving it, obtaining and
applying several patches and then running autoconf and configure before you even
have  makefile to use with make. Being able to run make means you can see the
light at the end of the tunnel.

I suspect you will not get very far trying to use DMAKE for building GNAT.

I haven't accessed Fidonet for a long time, and most people don't use it much
these days.
If you have any news can you post it here or on comp.os.os2.programmer.misc?

I'm hoping to build up unixos2.org as the major file repository for apps which
are normally ported from a Unix environment. I'd like to get it on there if/when
you manage to build it. Hope that's OK...

I built gcc2.7.x and 2.8.x in about 5 hours wall 
clock time on a Sun 10/51.

A good PC from the late 90s should do it in less time.

And yes i had the the make invocations in my head at that time.

And no i don't have access to a PC with OS/2 on !!
Send me one and i could take a look on gcc/gnat...

The problem is not the speed of the machine but under OS/2 and Windows you
have to fight the fact that all scripts and makefile are UNIX oriented.

And this is really time consumming.

Pascal is talking about Windows, which he is certainly familiar with.
What he says really does not apply to OS/2 (I don't believe Pascal
has ever done the GNAT build in OS/2 as far as I know). In fact the
build on OS/2 is fairly straightforward for anyone familiar with
OS/2, EMX, and GCC. Certainly *nothing* like the huge effort required
to build under Windows (which consumes a huge amount of ACT's time :-)

I'm not a particularly useful detailed source of knowledge on how to
build the OS/2 release from sources at this stage. I have a very
specialized set of makefiles setup on my personal machine which are
very specifically tuned for the way I do development.

Of course! And in any case, you need to assume that ALL the directions
are ones that should be followed. Generally it is assumed that you are
completely familiar with building gcc on the given target. I would
start by making sure you understand how to obtain the sources for gcc
on OS/2 and build from sources, only at the stage that you feel
reasonably familiar with the gcc build process and its make file can
you reasonably expect to be able to build GNAT.

You need to be at the stage where you don't need to ask such
questions. So once again, what I advise is obtain the GCC 2.8.1
sources and make sure that you can bootstrap a working version
of GNU C for OS/2, then once you have sorted out the problems in
doing that, you can go back to the GNAT build instructions and
they should be clear. If you can't build GNU-C, you are not going
to be able to build GNAT.

Unfortunately, I don't really want to actually build GNAT 3.13p, I just want to use
it on OS/2.
Is there any way to get hold of a pre-built binary just like NT people can?
