Version 10.3.1-2.3 is a maintenance release; it adds support for Apple Silicon and uses the latest build scripts.

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

There are binaries for x64 Windows, macOS (Intel 64-bit, Apple Silicon 64-bit) and GNU/Linux (Intel 32/64-bit, Arm 32/64-bit).

Raspberry Pi

The main targets for the GNU/Linux Arm binaries are the Raspberry Pi class devices (armv7l and aarch64; armv6 is not supported).

Download​

The binary files are available from GitHub Releases.

Prerequisites​

  • x86/x64 GNU/Linux: any system with GLIBC 2.15 or higher (like Ubuntu 12 or later, Debian 8 or later, RedHat/CentOS 7 later, Fedora 20 or later, etc)
  • arm64/arm GNU/Linux: any system with GLIBC 2.23 or higher (like Ubuntu 16 or later, Debian 9 or later, RedHat/CentOS 8 or later, Fedora 24 or later, etc)
  • x86/x64 Windows: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
  • x64 macOS: 10.13 or later

The current version is based on:

  • GNU Arm Embedded Toolchain release 10.3-2021.10 from October 21, 2021 and uses the gcc-arm-none-eabi-{frontMatter.arm_version}-src.tar.bz2 source invariant. It includes:
    • GCC 10.3.1
    • binutils 2.36
    • newlib 4.1.0
    • GDB 10.2

For more details see the original Arm release text files:

  • distro-info/arm-readme.txt
  • distro-info/arm-release.txt

Changes​

Compared to the Arm version, there should be no functional changes.

Python​

Support for Python scripting was added to GDB. This distribution provides a separate binary, arm-none-eabi-gdb-py3 with support for Python 3.7.

The Python 3 run-time is included, so GDB does not need any version of Python to be installed, and is insensitive to the presence of other versions.

Support for Python 2 was discontinued.

Text User Interface (TUI)​

Support for TUI was added to GDB. The ncurses library (v6.2) was added to the distribution.

note

TUI is not available on Windows

Documentation​

The original documentation is available in the share/doc folder.

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.

The scripts used to build this distribution are in:

  • distro-info/scripts

For the prerequisites and more details on the build procedure, please see the README-MAINTAINER 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​

32-bit support​

Support for 32-bit Intel Linux and Intel Windows will most probably be dropped in 2022. Support for 32-bit Arm Linux will be preserved for a while, due to the large user base of 32-bit Raspberry Pi systems.

Linux minimum requirements​

Support for RedHat 7 will most probably be dropped in 2022, and the minimum requirement will be raised to GLIBC 2.27, available starting with Ubuntu 18 and RedHat 8.
