The two Ada 95 possibilities on the MAC so far are

1. GNAT, which runs under Machten. This is the full GNAT system,
although it is volunteer port, not one that is supported by
Ada Core Technologies. Probably Jim Hopper will post some follow
up information.

2. Applet Magic from Averstar, which provides a subset
implementation based on the JVM. I don't know the status of
this, so perhaps Tucker can fill in here.

An interesting possibility for the future is JGNAT, which is
a more complete implementation of Ada 95 for the JVM, and
getting more complete every day (we are definitely aiming to
validate this system). There is no conceptual reason why
JGNAT should not run on a MAC, though I don't know of anyone
who has tried this port yet.

Note that I did NOT include the possibility of using the
Averstar Ada95 compiler that uses C as an intermediate
language because last I knew this was definitely not
free or close to free :-) [in either sense of the f word)

Is there a free (or close to free) Ada95 compiler for Mac G3s (iMac)?
If so, does it provide a Toolbox library?

Jim Hopper's volunteer port of GNAT is available from

You can get more information about Tenon's GNU development tools for

How likely are problems using these on an iMac

Wes,

they work fine with 9.04, however the bindings dont have the latest
bindings in them so OS 9 specific stuff you will have to roll your own. 
but its not to tough given the example of Johns Binding.

Ada on Mac

[Maciej Sobczak]

Hi,

I tried to find what are the options for using Ada on Mac OS X.
The archives of comp.lang.ada show only some old posts, so I hope to get 
some more up to date information after asking afresh.

I have found the following:

http://www.macada.org/compiler.html

http://sourceforge.net/project/showfiles.php?group_id=132622&package_id=146743

Do you have any (strong?) opinions on these?
Would you recommend something else?

The objective is to have a free compiler for personal use.

You are in the right neighborhood. The official site for Ada on Mac is
macada.org but it is out of date and thus gives a poor first
impression--the Mac Ada community is actually quite strong. There is a
new "experimental" web site at http://www.macada.org/macada/macada/Welcome.html.

**DO** join the mailing list which is very responsive. GNAT 4.2 and
4.3 are available as is a plug-in for Xcode, all in a proper Mac-style
installer.

OK, thank you for the link.
The package installed correctly (not counting the fact that I have 
downloaded the i386 package whereas the labels in the installation 
window were always PPC - this seems to be a label-only issue).

The compiler works fine, but somehow I cannot link:

~/temp/ada $ gnatmake hello
gcc -c hello.adb
gnatbind -x hello.ali
gnatlink hello.ali
/usr/bin/ld: Undefined symbols:
__Unwind_Resume

gnatlink: cannot call /usr/local/ada-4.2/bin/gcc
gnatmake: *** link failed.
~/temp/ada $

I have noticed that there is a separate toolchain, complete together 
with gcc, in /usr/local/ada-4.2/bin, so I have added that to my PATH (at 
the beginning).
Still, the linker fails.

Running gnatlink -v -v on the .ali file gives this output:

~/temp/ada $ gnatlink -v -v hello.ali

Yes, but Drew Reynolds is the one you want to talk to, and he'll
respond lots faster on the GNAT-OSX list.

I'm sure I've seen this problem on that list, but I do not know the
solution since I haven't
yet installed GNAT on my MacBook. If it has come up before, you'll get
even faster response.

The missing symbols are in libgcc_s.1.dylib. Depending on your 
LD_LIBRARY PATH, you may have to specify the search path, too:

gnatmake hello -largs -L/usr/local/ada-4.2/lib -lgcc_s.1

This is a problem in the 4.2 compiler; it's fixed in 4.3, but that has 
other problems; 3.3 is very stable, but a tad old:-)

See www.macada.org. Download the Leopard installer for GNAT and you're 
up and running. Make sure you've installed Apple's Developer Tools 
first, especially the XCode tools. They're in the optional-installs 
folder on your system disk.

GNAT/Mac comes with a plug-in for XCode (which is Apple's standard 
developer IDE). It's pretty much like all the other IDEs you've seen.

I agree about Xcode.

www.macada.org is quirky so make sure you sign up for the mailing list
if you have any problems.

There are a couple of free editors with IDE features of note that are
Ada-friendly. Check out Smultron and TextWrangler. Not free ($49) but
highly recommended is TextMate.

Yes, and a recent edition of Emacs runs "graphically"
on Mac OS X, not just in a terminal window.

Eclipse runs well, too.

There is Carbon Emacs and Aquamacs Emacs and MacVim and TextForge.

Slightly afield, but every Mac user should know about Versiontracker

Funny that you ask, I just created one:

http://sourceforge.net/project/showfiles.php?group_id=12974&package_id=291480

needs http://www.macports.org/ to be installed first.

But then there is also MacAda:

http://www.macada.org/

Which works with XCode.

The Wikibook page at http://en.wikibooks.org/wiki/Ada_Programming/Installing
lists both macada and the GNU Ada project in separate sections (resp.
4.5.9 and 4.3 in the table of contents) but it doesn't list Max OS as
supported in the GNU Ada project, nor does it explain the differences
between the two. Could someone in the know please add the appropriate
information for the benefit of all?

In particular I am curious how a hypothetical programmer wanting to
program in Ada on their Macintosh would choose between the two. Are
there differences in licensing? Integration with the rest of the
system? Libraries included?

Well my hope was to upstream to MacPorts in which case an MacPorts
section would be needed - and then listing differences would be interesting.

Currently GNU Ada is just staging area for a MacPosts version.

However, my upstream patches where not received well:

https://trac.macports.org/ticket/16549

Plan B would be a fork either as a part of MacPorts or inside GNU Ada
Project.

Once here truly is a MacPorts version the differences would be explained
in the line of integration: MacAda aims to integrate GNAT with the
existing Mac OS X development environment (read XCode) while MacPorts is
about integrating Mac OS X with the rest of the Unix world (read
"configure make install).

I think you misunderstood ryandesign's objection about the bootstrap
compiler. He doesn't say you should not need a bootstrap compiler; he
says that if you do, then the port must download and install the
bootstrap compiler automatically before building (re-read his last
sentence).

Also, it would be nice if you considered an entirely new port called
gnat43 which does require (and install) the MacAda compiler, but uses
the same sources as gcc43. This is what Debian does: gcj, gpc, gdc and
gnat are separate from gcc for this very reason.

(I replied here because I can't figure out how to contribute to the
ticket directly).

That's interesting. Could you elaborate on the practical consequences?

I know and I thought about it - but and automated dmg/pkg installation
of an >100MB package? And really one would need to deinstall the package
afterwards.

I did consider that - and it is my plan B. But it does feel like a fork.
Note that MacPorts - unlike other package systems installs all GCC core
languages (but ot Ada) with as one package. Probably due to the "gento"
 source code based way of live.

I thought that is pretty simple. Ahh, well...

MacPorts comes with Gtk, GNU tools, etc. pp which will make it easier to
port - for example - the gps. There is also a MacPort version of QT4 -
so QtAda might work with MacPorts as well.

However - there is currently no IDE for MacPorts while MacAda has XCode.

Yes indeed, but this is only necessary for the first version of gnat.
Subsequent versions can rely on the previous version and not require
anything from MacAda anymore.

I think the added build-dependency on a bootstrap compiler justifies a
fork of the build scripts, which you would maintain in parallel with
the "core" scripts and merge from them perdiodically. On the other
hand, you really want to build from the same upstream sources and the
same patches as the "core" gcc43. See [1] for an explanation of how
Debian achieves this.
