Version 10.2.1-1.1 is a new release of xPack GNU Arm Embedded GCC, following Arm release from Dec 11, 2020 (version 10-2020-q4-major).

The xPack GNU Arm Embedded GCC is the xPack distribution of the GNU Arm Embedded Toolchain.

There are binaries for x64 Windows, macOS (Intel 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.

note

For consistency with the Node.js naming conventions, the names of the Intel 32-bit images are now suffixed with -ia32.

Install​

The full details of installing the xPack GNU Arm Embedded GCC on various platforms are presented in the Install Guide.

Compliance​

  • GNU Arm Embedded Toolchain release 10-2020-q4-major from December 11, 2020 and uses the gcc-arm-none-eabi-{frontMatter.arm_version}-src.tar.bz2 source invariant. It includes:
    • GCC 10.2.1
    • binutils 2.35
    • newlib 3.3.0

Changes​

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

Starting with 9.x, the new archives are created with a single folder named xpack-arm-none-eabi-gcc-10.2.1-1.1 instead of the hierarchical xPacks/arm-none-eabi-gcc/10.2.1-1.1. This internal folder name is used consistently on all platforms. The archive extension was changed to .tar.gz.

With these changes, the archives can now be used directly in other development environments (like Arduino), without having to repack them.

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 PDF documentation is available in the share/doc folder.

Supported platforms​

Binaries for Windows, macOS and GNU/Linux are provided.

The binaries 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.

  • x86/x64 GNU/Linux: all binaries were built with GCC 9.3, running in an Ubuntu 12 Docker container
  • arm64/arm GNU/Linux: all binaries were built with GCC 9.3, running in an Ubuntu 16 Docker container (added in mid-2020)
  • x86/x64 Windows: all binaries were built with mingw-w64 GCC 9.3, running in an Ubuntu 12 Docker container
  • x64 macOS: all binaries were built with GCC 9.3, running in a separate folder on macOS 10.10.5.

Build​

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.

Travis tests​

The first set of tests were performed on Travis, by running a simple script to check if the binaries start and compile several simple programs on a wide range of platforms and distributions:

Tests​

The binaries were testes on Windows 10 Pro 32/64-bit, Ubuntu 18 LTS 64-bit, Xubuntu 18 LTS 32-bit and macOS 10.13.

The tests consist in building and debugging some simple Eclipse projects available in the project.

Since the source code used for GCC is identical to the one used by Arm, the long and complex tests performed by Arm to validate their release were not executed again.
