Does GNAT GPL 2010 have C++?

Does GNAT GPL 2010 have C++?

[Jerry]

According to the Adacore Libre site

http://libre.adacore.com/libre/tools/gnat-gpl-edition/

the 2010 GPL GNAT includes Ada, C, and C++. Yet, there is this on my
OS X 10.5:

MBPro:bin jb$ ./gcc -v

No C++? What am I missing here?

It was similar with 2009. Interestingly, the package for Windows does
have the g++
part (or at least it did for 2009 - is it still true for 2010?).

I think that plain sloppiness is the only explanation for this
inconsistency.
Although the fact that it happens again is a food for thought.

Well, that's not good news. It's preventing me from building PLplot on
OS X 10.5.

I wonder if we'll have to wait another year for a fix?

Why not build GNAT and G++ yourself?

Because it might take even longer, especially without the necessary
experience.

Consider this: some time ago there was a discussion here about selling
Ada to the C shop. Take into account that in practice "the C shop"
will be "the C++ shop". Now, a very strong argument for Ada was that
it can integrate with existing codebase by means of interfacing and
direct linking. Guess what - it will not work for this shop without
the C++ compiler that is ABI-consistent with the C and Ada parts.
And the suggestion to build GNAT and g++ yourself is a sure way to
abandon the whole proposal.

It is in the best interest of AdaCore to produce consistent package
that targets C++ together with C and Ada. Without it many programmers
and whole shops will simply be discouraged from considering Ada
seriously.

Or maybe it does not really matter that much for the Mac OS X.
I don't know what AdaCore thinks about it, but certainly I would like
to see a complete package for Mac.

I wonder how much time it would take for a complete noob (e.g., me) to
do this. Is the source provided as a download from Adacore the same as
what they use for their build? I would hope so. If that's the case,
then it seems that the problem of the missing C++ compiler should be
fixable by changing only one argument.

It's a middling-complex job, which I've done quite a few times now, and
am about to start for GNAT GPL 2010 now you've suggested it -- but only
for Snow Leopard, I'm afraid. For starters, you need to build libgmp and
libmpfr.

It's a tad late now, so I need to catch some sleep, but I _will_ write
down the steps!

That would be awesome. In that case, I would just move to 10.6 and
figure out whatever other issues there would be with my workflow.

Do you normally include Fortran or other languages in your builds?

'normally' I'd just include Ada & C. But I've recently needed to
include Fortran (for the math extension project, to generate test data
sets), so C++ shouldn't be a huge problem. I think the 'make check'
part might be interesting, I gather it takes a loong time for C++ ...

OK.

Things didn't go as well as I'd hoped, in particular there's no Fortran;
GNAT GPL 2010 is built on "GCC 4.3.6", which doesn't appear on any GNU
download site, so I can't get the Fortran component which is missing
from the GNAT sources. I suppose I could have tried out the 4.3.5
version ...

Anyway, the download is at http://sourceforge.net/projects/gnuada/files/
-- at the moment it's the newest file, otherwise navigate > GNAT_GPL Mac
OS X > 2010-snow-leopard.

This means it's taken off the gcc-4_3-branch, presumably after the
release of 4.3.5.

Thanks for your help, Simon. You might want to post this to the GNAT-
OSX list.

But perhaps less likely an OS X shop. There must be some economical
tradeoffs for AdaCore in respect of dedicating resources for building
such or such marginal element of their free packages.

I think MacOS comes with a system C++ compiler (unlike Windows), so
this shouldn't be an issue.

Sorry, I wasn't clear in my original statement. What I meant to say
was that it's preventing me from building PLplot with a 64-bit
compiler on OS X 10.5 Leopard.

I was surprised to discover that the Apple-supplied gcc on 10.5
Leopard is 32-bit: otherwise, I could have compiled the Ada parts on
Adacore's GPL and the C++ parts with Apple's gcc.

The reasons for wanting to use Adacore's 2010 GPL are (to a lesser
extent) that it finally fixes the linking to BLAS and LAPACK and fixes
the problem with the non-blocking Get_Immediate, and (to a greater
extent) I want to evaluate GPS, and the installation of the whole
thing is really easy. I don't know whether I can replace only the
compiler in all of that (the Adacore package) and expect the tools
such as GPS to still work. Another important reason is that, as the
"Ada guy" on the PLplot dev team, I wanted to make some effort to see
that a 64-bit installation on Leopard is possible.

I suppose that even with the deficiency in the Adacore compiler, I
could achieve a 64-bit build on  10.6 Snow Leopard but I have lagged
behind in moving to that OS because of hassles in getting the Xcode
IDE to work with Ada.

There have been Mac-specific problems, as there are for many
platforms. GCC 4.5.0 builds fine on Mac OS X Snow Leopard (though I've
only added Fortran, not C++).

If there is a community of interest, it'd be simple enough to try
building GNAT GPL 2010 with C++ ...

FWIW, I've been using this one for a while on Mac OS X 10.5:
