Release GCC 14.1.0 (aarch64) · simonjwright/building-gcc-macos-native

This is GCC 14.1.0 built on macOS Sonoma (14, Darwin 23) but able to run on Monterey, for Apple silicon (M1), with Command Line Utilities 15.3.0 and Python 3.9.13.

Compiler sources are from https://github.com/iains/gcc-14-branch at tag gcc-14.1-darwin-r0.

Compilers included: Ada, C, C++.

Tools included (all at version 24.0.0, and all with the Runtime Library Exception):

AdaSAT from https://github.com/AdaCore/AdaSAT
AUnit from https://github.com/AdaCore/aunit
GNATCOLL from:
- https://github.com/AdaCore/gnatcoll-core
- https://github.com/AdaCore/gnatcoll-bindings (ZLIB is included, OMP and LZMA are not (the GNATCOLL version for LZMA requires thread support in the system library, not available on macOS))
- https://github.com/AdaCore/gnatcoll-db (only the SQLite backend)
Gprbuild from https://github.com/AdaCore/gprbuild
Gprconfig_kb from https://github.com/AdaCore/gprconfig_kb
GPR2 from https://github.com/AdaCore/gpr (but not the tools, some don't quite match the behaviour of corresponding tools in GPRbuild)
Langkit from https://github.com/AdaCore/langkit
Libadalang from https://github.com/AdaCore/libadalang
Libadalang tools from https://github.com/AdaCore/libadalang-tools
Templates Parser from https://github.com/AdaCore/templates-parser

Install

One of Xcode or the Command Line Tools is required.

Xcode can be downloaded from the App Store.
Install the Command Line Tools by sudo xcode-select --install.

If you suspect your copy of the Command Line Tools is old, you can delete it by

sudo rm -rf /Library/Developer/CommandLineTools

and re-install.

Download the binary .pkg. It's not signed, so don't double-click on it; instead, right-click on it and Open. Accept the warning. You will be guided through the installation.

Setting PATH

PATH needs to be set to include /opt/gcc-14.1.0-aarch64/bin at the front:

`bash`

Insert

export PATH=/opt/gcc-14.1.0-aarch64/bin:$PATH

in your ~/.bash_profile_common.

`zsh`

Likewise, but in ~/.zshrc.

See here for helpful information on moving to zsh.

Notes

The software was built using the building-gcc-macos-native scripts at Github, tag gcc-14.1.0-aarch64.

All compilations were done with export MACOSX_DEPLOYMENT_TARGET=12 so that libraries and executables are compatible with macOS Monterey and later.

Compiler

The compiler is GPL version 3. The runtime has the GCC Runtime Exception, so executables built with it can be released on proprietary terms.

GMP

This library (release 6.2.1) is installed with the compiler.

Other sources

The following patches to the v24.0.0 versions were needed to allow the builds to see the new compiler.

Include, library paths

As noted here, Apple have changed the location of system include files and libraries; they used to be copied from the SDKs to the "standard" /usr/include and /usr/lib either automatically or on command.

This compiler has been built so you don't need to take any related action to use it: unfortunately, this means that paths in /usr/local and /Library/Frameworks aren't searched.
