Setting up the build environment on MacOS does not require an AppleID or need anything from the App store. Everything is done from the Terminal. MacOS uses Clang compiler by default which has caused issues. GCC is strongly recommended. Setting up the build environment on MacOS does not require an AppleID or need anything from the App store. Everything is done from the Terminal. MacOS uses Clang compiler by default which works on ARM64 but has problems on MACs with x86_64 which need to be compiled with GCC.

Homebrew compiles packages from source which can take a long time. Once install is finished find gcc. gcc is linked to clang so it's necessary to include the version to actually call gcc. Homebrew compiles packages from source which can take a long time.
The easiest way is tyo type `gcc-` then hit TAB for command completion. If multiple versions are installed they will all be listed. To use gcc the CC & CXX environment variables must be defined with the version included. At time of writing gcc-14 is the default, change version as required. The variables may be set in the shell profile, in CFLAGS or from the command line at user's preference. Compiling for ARM64 currently only works with Clang, x86_64 requires GCC.
