xPack GNU Arm Embedded GCC v10.2.1-1.1 released
The xPack GNU Arm Embedded GCC is the xPack distribution of the GNU Arm Embedded Toolchain.
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.
The full details of installing the xPack GNU Arm Embedded GCC on various platforms are presented in the separate Install page.
The easiest way to install GNU Arm Embedded GCC is with
by using the binary xPack, available as

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
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
With these changes, the archives can now be used directly in other development environments (like Arduino), without having to repack them.
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
On all platforms the packages are standalone, and expect only the standard runtime to be present on the host.
All dependencies that are build as shared libraries are copied locally in the same folder as the executable.
On GNU/Linux the binaries are adjusted to use a relative path:
$ readelf -d library.so | grep rpath 0x000000000000001d (RPATH) Library runpath: [$ORIGIN]

LD_LIBRARY_PATH, and does not tolerate setting
it in the environment.
Similarly, on macOS, the binaries are adjusted with

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.
- Intel GNU/Linux: all binaries were built with GCC 9.3, running in an Ubuntu 12 Docker container
- Arm GNU/Linux: all binaries were built with GCC 9.3, running in an Ubuntu 16 Docker container (added in mid-2020)
- Windows: all binaries were built with mingw-w64 GCC 9.3, running in an Ubuntu 12 Docker container
- Intel macOS: all binaries were built with GCC 9.3, running in a separate folder on macOS 10.10.5.
The scripts used to build this distribution are in:
For the prerequisites and more details on the build procedure, please see the README-MAINTAINER page.
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:
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.
