I have gnat 13.1.0 on my M1 Mac; I'd like to have my own Ada+GNAT *.ad[sb] library files, where are they?

[Kenneth Wolcott]

Hi;

I have gnat 13.1.0 on my M1 Mac;

(thank you, Simon! <GRIN>)

I'd like to have my own Ada+GNAT *.ad[sb] library files, where are they?

I can find the Ada libraries (*.ad[sb]) but it sometimes is hard to (reliably) find all of the GNAT Ada libraries in external documentation.

I hope that this is not a stupid question.

Perhaps there is a gnatmake flag or gnat doc that I'm just not seeing.

Thanks,
Ken Wolcott

If you just want to insect them, see below: if you want to alter them,
that'd be a bit tricker. As far as I can remember, GNAT Pro releases
provide for rebuilding the runtime, but the FSF builds don't.

They're in {prefix}/lib/gcc/{target}/{release}/adainclude/ - i.e., in
your case (unless you've moved the install)

/opt/gcc-13.1.0-aarch64/lib/gcc/aarch64-apple-darwin21/13.1.0/adainclude/

But you say you know that. I wonder whether it's the crunched filenames
that are confusing? (a legacy of the days when DOS 8.3 filenames were
required for a large part of GNAT's target audience). You can find the
crunched filename for a package using gnatkr (gnat krunch):

$ gnatkr gnatkr ada.sequential_io.ads
a-sequio.ads

(you don't actually need whatever's after the final period to be the
actual file extension: you could use '.open' or just '.').

Only one 'gnatkr', ofc!

Thank you Simon!

This is all the information that I needed, thank you!

This is nice, thank you!

Which raises a question: Why does GNAT still use crunched filenames? It
probably makes sense to continue to support them (does anyone use GNAT
on MS-DOS?), but I wouldn't think it would be difficult to use full file
names on the vast majority of systems that support them. It's not a
huge deal, but using full file names where possible would be less
annoying.

Unless they changed how the GNAT compiler works in the last few years, then my guess is inertia
to do that. Right before the pandemic hit, I had the neat idea of doing my own bare metal
runtime and to use normal uncrunched names. The RTS compiled just fine doing that. However,
when I tried to use the RTS to build a full fledged program, it failed to find the package in the RTS.
I don't recall if it failed at compile time or link time, but crunching the names and recompiling the
RTS fixed the issue. So something in their compiler requires the crunched names, or if they have
since changed that, used to require it.

Simon, Keith, Jere:

Yes, the crunched names are annoying. Too bad that they seem to be required even now...

I'm now writing a Perl script (later to be converted to Ada) which does the "unkrunch" :-)

Seems like a missing utility for humans to use Ada :-)

Thanks,
Ken

The package in the compiler that deals with crunched names is Rtsfind,
