GNAT 2009 and C++

GNAT 2009 and C++

[Maciej Sobczak]

The GNAT GPL 2009 from the Libre site does not seem to include the g++
compiler, only gcc is provided. As a result it is not possible to link
a complete program from components written in both Ada and C++.
Well, at least this is not possible on Max OS X, where after setting
up the GNAT 2009 environment the following commands:

$ gcc --version
$ g++ --version

give different numbers (the first comes from the GNAT distribution and
overrides the standard compiler and the other one is still the
standard system version).

The distribution from macada.org contains both g++ and gcc compilers
and the above problem does not appear.

Do other GNAT 2009 users consider it to be a problem?

If yes, would it be possible to include a consistent C++ compiler in
the GNAT distribution as well?
(this is a question to AdaCore, of course ;-) )

I got exact the same version on both Windows(MinGW) and Red Hat. One
interesting note is that the result of 'gcc --version' command is not
exact the same as 'gcc -v' command. In fact, when using command g++ --
version, the result is:

$ g++ --version
g++.exe (GCC) 4.3.4 20090511 for GNAT GPL 2009 (20090511)

However, if command 'g++ -v' is used, the result is quite different as

This line suggests that you got the g++ compiler with your GNAT
distribution.
Why is it not included with the Mac OS X version?

This has always been the case for GCC. -v is _not_ a shortcut for --version.

-v is the short version of --verbose , not --version.
