There are separate binaries for Windows (Intel 32/64-bit), macOS (Intel 64-bit) and GNU/Linux (Intel 32/64-bit, Arm 32/64-bit).
The binary files are available from GitHub Releases.
- Intel GNU/Linux 32/64-bit: 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)
- Arm GNU/Linux 32/64-bit: 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)
- Intel Windows 32/64-bit: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
- Intel macOS 64-bit: 10.13 or later
The full details of installing the xPack GNU Arm Embedded GCC on various platforms are presented in the separate Install page.
xpm tool available, installing
the latest version of the package and adding it as
a dependency for a project is quite easy:
cd my-project xpm init # Only at first use. xpm install @xpack-dev-tools/arm-none-eabi-gcc@latest ls -l xpacks/.bin
To install this specific version, use:
xpm install @firstname.lastname@example.org
For xPacks aware tools, like the Eclipse Embedded C/C++ plug-ins, it is also possible to install Arm Embedded GCC globally, in the user home folder.
xpm install --global @xpack-dev-tools/arm-none-eabi-gcc@latest
Eclipse will automatically
identify binaries installed with
xpm and provide a convenient method to manage paths.
To remove the links from the current project:
cd my-project xpm uninstall @xpack-dev-tools/arm-none-eabi-gcc
To completely remove the package from the global store:
xpm uninstall --global @xpack-dev-tools/arm-none-eabi-gcc
The xPack GNU Arm Embedded GCC generally follows the official Arm Embedded GCC releases.
The current version is based on:

Compared to the Arm version, there should be no functional changes.
Compared to 10.3.1-2.2, this release uses a new version of the build scripts, which provide a better control over the content of the binary objects, and thus is able to further optimize the size of the libraries, resulting in slightly smaller archives.
Support for Python scripting was added to GDB. This distribution provides
a separate binary,
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 binaries for all supported platforms (Windows, macOS and Intel & Arm 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:

Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:
The binaries were tested on a variety of platforms, but mainly to check the integrity of the build, not the compiler functionality.

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.
