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-12.2.0-aarch64/bin at the front:
bash
Insert
export PATH=/opt/gcc-12.2.0-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-12.2.0-aarch64.
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.
The patch for PR104871 is included.
GMP, MPFR, MPC
These libraries (releases 6.2.1, 4.1.0, 1.2.1 respectively) are installed with the 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.
