OS X 10.8 Mountain Lion and GNAT GPL 2012

OS X 10.8 Mountain Lion and GNAT GPL 2012

[Bill Findlay]

Mountain Lion needs Xcode 4.4, which does not install by default the command
line tools /usr/bin{as, ld, make} needed by GNAT.

It is necessary to invoke:

  Xcode > Preferences... > Downloads  >  Command Line Tools: Install

It's about a 115MB download.

Once completed, GNAT GPL 2012 is resored to sanity.

Thanks for the heads-up.

I love my Mac, but can't help worrying about Apple's plans. When it gets
to the point that all you can do on a Mac is program for mobile devices
and watch cats on YouTube I shall have to tear myself away from it!

I suspect the GCC tools are now an optional download because Apple have
adopted LLVM in place of GCC as the standard compilation toolset.

I can't see them ever making it impossible to use GCC.

Indeed. I appreciate that the Mac can still be made easier to use by
"normal" users and thus the move to make the Mac like an iPhone/Pod/
Pad. But Apple keeps throwing out useful features in the interest of
improvement for the masses. I could make a list....

X11 is no longer included in OS X, even as an option.

I can't see how that can be blamed on "improvement for the masses".
They would not even have known that X11 existed.

In any case, OS X automatically redirects X11 users to Xquartz, which
provides a more up-to-date open source alternative.

Hello Bill, is gdb from GNAT GPL 2012 working well?
Mine seems to have codesign issue:
Unable to find Mach task port for process-id 11280: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

Have you try it?

Thanks, Pascal.

Hi Pascal: short answer is no.

In fact, I have never used any debugger for my Ada work.

Sorry I can't be more help.

Wow. That's going to be a problem--on top of the other gdb/Ada/OS X issues we've had / are having.

Can anyone else report on gdb with GNAT GPL 2012 and Mountain Lion OS X 10.8?

That's not surprising since both of these updates are relatively new. I personally have not updated either and am on GNAT 2011 and OS X 10.7.4. I wonder if, with 2012 and 10.8, for example, gdb honors breaking on Ada exceptions.

Thanks for that link, Georg.

Today's (yesterday's) update to Lion, 10.7.5, brings Gatekeeper to Lion (not just for Mountain Lion any more). So if I update to 10.7.5, I gather that I can expect gdb to stop working. But if I follow the instructions on the linked page, I presume that gdb will continue to work, even if it is not freshly compiled but is e.g. from GPL 2011.

I just updated to 10.7.5.

The gdb from GNAT GPL 2012 seemed to work fine: it's

 $ ls -l /opt/gnat-gpl-2012/bin/gdb
 -rwxr-sr-x@ 1 simon  procmod  5479472 14 May 15:25 /opt/gnat-gpl-2012/bin/gdb

/usr/bin/gdb, on the other hand, isn't setgid procmod and (the first
time I ran it) put up a dialog box asking for my password.

I have /System/Library/LaunchDaemons/com.apple.taskgated.plist set up to
run taskgated with -p -s.

Yes Simon, in fact with ML, taskgated isn't launched with option -p (manual said: old (Tiger) convention that a process with a primary effective group of procmod or procview is allowed to get task ports. Without this option, this legacy mode is not supported.)
As you said for Lion, and in my case with SL, taksgated was launched with option -p.
Thus with ML even gdb has setgid procmod group, it is blocked by taskgated.

Fortunately the -s option of taksgated (active with both SL and ML) let us codesign gdb to proceed.
Well, GNAT gdb is already signed:
Authority=gnat_debugger
Signed Time=14 mai 2012 16:25:55
It seems that taksgated need a local system signature thus we have to follow instructions on http://sourceware.org/gdb/wiki/BuildingOnDarwin.
And we must force it with -f option:
$ codesign -fs gnat_gdb gdb
gdb: replacing existing signature
It is now ok.

Don't forgot to add option '-largs -Wl,-no_pie' if you want to get good line numbers.

HTH, Pascal.

I too was baffled by this (the phrase was something like "must be
