Hi,
I am sorting out some issues building RTEMS on MacOS including the M processors.
The building gcc-12.2.1 for the few architectures I tested fail with sig faults
in xgcc when building the runtime. I tried arm, aarch64 and sparc. As a result I
wondered about bootstrapping gcc and using that to build the tools rather than
clang from Xcode.
Is aarch64-apple-darwin supported? I am seeing:
*** Configuration aarch64-apple-darwin22.3.0 not supported
Thanks
Chris

No. Iain Sandoe has some personal branches with changes to support it, but
the changes are not in the official gcc repo yet. If you search the
gcc-help@gcc.gnu.org list you'll find links to his code. I think Homebrew
is his patches too.

I tried Iain's repo and it fails in the same way.
I have been building the tools on MacOS for over a decade with just the Apple
base to make sure we have a clean platform without any issues. To do that I
avoid MacPorts and Homebrew. I am fine with our users making use of those
packages however knowing a build works with just the Apple support makes our
support simpler.

I am able to build gcc from Iain's repo gcc-darwin-arm64 on an M1 Mini,
running macos 11.3.1, using the following configuration. (Change your
language preferences accordingly.) I used make -j4.
CC=/opt/homebrew/bin/gcc-12 \
CXX=/opt/homebrew/bin/g++-12 \
../../src/gcc-darwin-arm64/configure \
--prefix=$HOME/gm2/arm64 \
--exec-prefix=$HOME/gm2/arm64 \
--enable-languages=c,c++,m2 \
--with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk \
--with-mpc=/opt/homebrew \
--with-gmp=/opt/homebrew \
--with-mpfr=/opt/homebrew \
--disable-bootstrap \
--enable-threads=posix
However, you must first define HAVE_FCNTL_H to 1 in libiberty/config.h
(that is missed somehow by configure).
Sincerely,
N.

Thanks for this. It was helpful.
I installed homebrew and the `gcc` package and updated the RTEMS RSB to use
homebrew if installed. I can build RTEMS tools:
% /Users/chris/development/rtems/6/bin/sparc-rtems6-gcc --version
sparc-rtems6-gcc (GCC) 12.2.1 20230224 (RTEMS 6, RSB
f0e34eab8bf33b833a7d9d0b2bddd3b89f6d83cb-modified, Newlib 17ac400)

% file /Users/chris/development/rtems/6/bin/sparc-rtems6-gcc
/Users/chris/development/rtems/6/bin/sparc-rtems6-gcc: Mach-O 64-bit executable

This will work for us. Thanks to those who responded.
