macOS Ventura 13.6 update problem

[moi]

Installing the macOS Ventura 13.6 security update clobbers GNAT.
Specifically, the link stage fails:

Simon's "magic formula", '-largs -Wl,-ld_classic' restores sanity.
I guess the CLTs were updated without asking permission. 8-(

I managed to avoid this this morning (I've been resisting the attempted
upgrade to CLT 15.0) by looking to see what was proposed, seeing that
there were 2 upgrades (Ventura & CLT), and unchecking the CLT.

Iain Sandoe recommends[1] re-installing 14.3 (you should be able to
download it from the developer.apple.com website, although you do need
an apple ID to do that)

And now it proposes to install it tonight. Ugh. Investigating what
happens if I turn off automatic installation of macOS updates ...

Hmm, this is odd. I'm having no problems.
I'm running mac OS Ventura 13.6 (with the security update), CLT 15.0
and gnat based on gcc 13.1.

[moi]

Ah!
I'm still on GNAT 12.2.0.

I should have added that, although the link phase works,
it produces this message, which is new:

> -macosx_version_min has been renamed to -macos_version_min

And Free Pascal Compiler version 3.2.2 [2021/05/16] for x86_64
also complains, thus;

> ld: warning: -multiply_defined is obsolete

But again, the linking succeeds.

I was under the impression that 13.6 _was_ a security update!

Investigation so far shows that linking against the static Ada runtime
(the default, -bargs -static) crashes, against the shared runtime
(-bargs -shared) is OK.

With 12.2.0, 13.1.0, 14.0.0.

I occurs to me that it might be _any_ static library? ... later

Yes, so it is. Damn.

Great. I already put off major macOS updated because I don't want to break a working system. Now I need to avoid „security“ updates as well. The „just works“ sale point is eroding.

Now I have to find out how that works.

It was actually the well hidden update of the Command Line Tools
accompanying th security update that caused the problem.
Just make sure to unselect the CLT update.

Just add "-largs -Wl,-ld_classic" to the linker parameters,
if you have updated the CLTs.

e.g. gnatmake foo.adb -largs -Wl,-ld_classic
or gprbuild -P foo -largs -Wl,-ld_classic
or alr build -- -largs -Wl,-ld_classic

The GNAT tools use gcc to drive the system linker ld. When gcc sees
-Wl,-foo,bar it sends "-foo bar" to ld (the 'l' means 'linker'; see the
GCC switches web page for the other possibilities).

When /usr/bin/ld (from Xcode 15) sees -ld_classic, rather than taking it
as an instruction to process libld_classic.{a,dylib}, it delegates the
actual link to /Library/Developer/CommandLineTools/usr/bin/ld-classic.

Wow.

You could always download the 15.1 beta version of the tools package
from developer.apple.com
