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 2.27, available starting with Ubuntu 18, Debian 10 and RedHat 8. Support for RedHat 7 was dropped in 2022.

32-bit support​

Support for 32-bit x86 GNU/Linux and x86 Windows was dropped in 2022.

Pre-deprecation notice for 32-bit Arm GNU/Linux​

Due to the large user base of 32-bit Raspberry Pi systems, support for 32-bit Arm GNU/Linux (armv7l) will be preserved for a little while, but expect it to be dropped by 2025, so it is recommended to consider an upgrade to a RPi 4 or 5 with at least 4 GB (preferably 8 GB) of RAM.

Pre-deprecation notice for Ubuntu 18.04​

Ubuntu 18.04 LTS Bionic Beaver reached the end of the standard five-year maintenance window for Long-Term Support (LTS) release on 31 May 2023.

As a courtesy, the xPack GNU/Linux releases will continue to be based on Ubuntu 18.04 for another year.

From 2025 onwards, the GNU/Linux binaries will be built on Debian 10, (GLIBC 2.28), and are also expected to run on RedHat 8.

Users are urged to update their build and test infrastructure to ensure a smooth transition to the next xPack releases.
