I installed 14.0, Sonoma, on my M1 Mac last night.

The good news:

Using GNAT 12.2.0, it all just works, *so long as* I REMOVE
'-largs -Wl,-ld_classic' from the linker options!

Likewise, but that didn't work for me.

It turns out there's an environment variable DEFAULT_LINKER, which with
the 15.0 CLT would be set to

export DEFAULT_LINKER=/Library/Developer/CommandLineTools/usr/bin/ld-classic

(the Xcode equivalent is much longer & more inscrutable)

I haven't tried this.

You can't reinstall the 14.3 CLT under Sonoma (it's "too old"). I
reinstalled from a Time Machine backup, but if you don't have that set
up I'd recommend taking a copy of /Library/Developer/CommandLineTools
before updating to 15.0.

What exactly is meant by "Using GNAT 12.2.0"? I put gcc-13.2.0 in ~/.zshrc. Then I got Could not locate executable on path: gprbuild.
What do i miss?

It means using the version that announces itself
at the head of the source listing as:

Hi Simon;

I'd recommend taking a copy of /Library/Developer/CommandLineTools

Well, I should have done this, but I didn't...

Are there any other workarounds to solve the inability to link? This does not only adversely affect Ada, but everything that uses a linker, BTW.

Thanks,

As I said above, this only affects building GCC, not using it. Sorry.

I have some evidence that the issue only arises with static
libraries. Not much help.

We're hoping that the 15.1 release of Command Line Tools fixes this. In
the meantime,

(1) using gnatmake, or gprbuild without changing the GPR:

$ gnatmake foo.adb -largs -Wl,-ld_classic
or
$ gprbuild -P foo -largs -Wl,-ld_classic

(2) modifying the GPR by adding a new package Linker:

package Linker is
for Default_Switches ("ada") use ("-Wl,-ld_classic");
end Linker;

(3) if you already have a package Linker, modify as above.

First, I asked above where you got GCC 13.2.0 from; you certainly didn't
get it from one of my builds.

If you got it via Homebrew, then be aware that homebrew's gcc *does*
*not* *support* *Ada* (or gprbuild).

There are two ways I know of for getting hold of GNAT and gprbuild:

(1) go to https://alire.ada.dev/docs/#introduction and follow the steps
at 'alr for macOS', then 'First steps' ... This provides GCC 12.2.0 for
x86_64 (intel), which runs on an M1/M2 mac under Rosetta.

(2) go to my release page at https://github.com/simonjwright/distributing-gcc/releases and download

for Intel: https://github.com/simonjwright/distributing-gcc/releases/tag/gcc-13.1.0-x86_64

for M1/M2: https://github.com/simonjwright/distributing-gcc/releases/tag/gcc-13.1.0-aarch64-2

(in both cases, the actual download is found under Assets at the bottom
of the page; but please read the release notes for what's included and
how to install).

I chose option #1a...

Using the Turtle Graphics Rosetta Code example for Ada, I was able to get a successful compile+link:

gnatmake main.adb -largs -Wl,-ld_classic
gcc -c main.adb
gnatbind -x main.ali
gnatlink main.ali -Wl,-ld_classic
-macosx_version_min has been renamed to -macos_version_min

Appreciate the suggestions...

Thanks,
Ken

This will be fixed in GCC 14.
