Version 11.2.1-1.1 is a new release; it follows the Arm release.

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

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

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 3.10.

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

Bug fixes​

  • none

Enhancements​

  • none

Known problems​

  • for unknown reasons, in the Arm distribution used as reference, support for parsing XML files in GDB was disabled; when connecting to SEGGER J-Link GDB server, the warning Can not parse XML target description; XML support was disabled at compile time is displayed and some functionality is not available; fixed in 11.2.1-1.2;
  • due to an error in the build scripts, the libgcov.a library resulted with empty content; fixed in 11.2.1-1.2.

Documentation​

The original GNU GCC documentation is available online.

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 was dropped in 2022. Support for 32-bit Arm Linux (armv7l) 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 was dropped in 2022 and the minimum requirement was raised to GLIBC 2.27, available starting with Ubuntu 18, Debian 10 and RedHat 8.
