Hello all,

We released GNAT FSF 15 on Alire yesterday. This release is based on GCC 15.1.0; the release notes for Ada can be found here.

There are prebuilt binaries for Linux (x86_64 and aarch64), Windows (x86_64) and macOS (x86_64 and aarch64). Please note that the binaries for macOS aarch64 are based on an unofficial branch of GCC that has not yet released a final version for GCC 15, so there may be some issues that are absent from other platforms.

Cross compilers are also available on all platforms for the following targets: arm-elf, riscv64-elf, avr-elf and xtensa-esp32-elf.

You can report issues with the released compilers on this repository.

We want to thank @simonjwright for his work on building GNAT for macOS. His work helped us greatly to provide functional compilers for the platform. He will be sorely missed.

Are there any links to the binaries?
I was looking for a couple, but didn’t find them.
Installing Alire isn’t always an option. (i.e. shared computers)

Alire, especially with GNAT FSF toolchain support is an incredible experience. Thanks for all the work everyone puts into this.

On macOS, please note that specific compiler and linker switches may be needed for C includes and libs to avoid these kind of errors:

  • stdint.h: No such file or directory
  • ld: library not found for -lSystem

I reported an issue.
