This note covers some of the considerations that’ll apply when running Alire on macOS.

Building GCC 12.2.0 on Ventura for aarch64

These are notes on building GCC 12.2.0 and GNAT tools for Apple silicon.

There were two main problems:

• the base package was built on an Intel machine (lockheed - named after Shadowcat’s companion dragon), running Monterey (macOS 12).
• the build machine, an M1 mac Mini (temeraire - named after Naomi Novik’s dragon) was by this time running Ventura (macOS 13), but I wanted to make sure that users could continue to run on Monterey.
