Version 15.2.1-1.1.1 is a new release; it follows the Arm release.

The xPack GNU Arm Embedded GCC is a standalone cross-platform binary distribution of Arm GNU Toolchain.

There are separate binaries for Windows (x64), macOS (x64 and arm64) and GNU/Linux (x64 and arm64).

Raspberry Pi

The main targets for the GNU/Linux Arm binaries are the Raspberry Pi class devices (aarch64 only; armv6 and armv7l are no longer supported).

Download​

The binary files are available from GitHub Releases.

Prerequisites​

  • x64 Windows: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10, Windows 11
  • x64 macOS: 11.0 or later
  • arm64 macOS: 11.0 or later
  • x64 GNU/Linux: any system with GLIBC 2.28 or higher (like Ubuntu 20 or later, Debian 10 or later, RedHat 8 or later, Fedora 29 or later, etc)
  • arm64 GNU/Linux: any system with GLIBC 2.28 or higher (like Raspberry Pi OS, Ubuntu 20 or later, Debian 10 or later, RedHat 8 or later, Fedora 29 or later, etc)

Install​

The easiest way to install this specific version, is by using xpm:

xpm install @xpack-dev-tools/arm-none-eabi-gcc@15.2.1-1.1.1 -verbose

Comprehensive instructions for installing xPack xPack GNU Arm Embedded GCC on different platforms can be found in the Install Guide.

Documentation​

The original GNU Arm Embedded GCC documentation is available from the GCC online documentation web site.

Build​

The binaries for all supported platforms (Windows, macOS and GNU/Linux) were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.

For the prerequisites and more details on the build procedure, please see the Maintainer Info page.

CI tests​

Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:

Tests​

The binaries were tested on a variety of platforms, but mainly to check the integrity of the build, not the compiler functionality.

Deprecation notices​

GNU/Linux minimum requirements​

The minimum requirement is GLIBC 2.28, available starting with Ubuntu 20, Debian 10 and RedHat 8. Support for RedHat 7 was dropped in 2022. Support for Ubuntu 18 was dropped in 2025.

32-bit support​

Support for 32-bit x64 GNU/Linux and x64 Windows was dropped in 2022 and for 32-bit Arm GNU/Linux in 2025.

Pre-deprecation notice for x64 macOS​

Apple has discontinued support for the x64 (Intel) architecture. GitHub will no longer support this architecture on macOS after the macOS 15 runner image is retired in November 2027; building and testing x64 macOS binaries will become more difficult, requiring a self-hosted runner, and cannot be guaranteed in the long term.

You should begin migrating your projects to arm64-based (Apple Silicon) binaries to prepare for this deprecation (tentatively planned for 2028).
