Overview
The xPack GNU Arm Embedded GCC is an alternate binary distribution that complements the official GNU Arm Embedded Toolchain maintained by Arm.
Benefits
The main advantages of using the xPack GNU Arm Embedded GCC are:
- a convenient, uniform and portable install/uninstall/upgrade procedure, the same procedure is used for all major platforms (Intel Windows 64-bit, Intel GNU/Linux 64-bit, Arm GNU/Linux 64/32-bit, Intel macOS 64-bit, Apple Silicon macOS 64-bit)
- a convenient integration with Continuous Integration environments, like GitHub Actions
- a better integration with development environments like Eclipse Embedded CDT.
All binaries are self-contained, they include all required libraries, and can be installed in any location.
Compatibility
The xPack GNU Arm Embedded GCC is fully compatible with the original GNU Arm Embedded Toolchain distribution by Arm.
Occasionally, when bugs are discovered and the yearly Arm release schedule would add unacceptably long delays, the xPack GNU Arm Embedded GCC moves ahead of Arm and uses more recent tools versions that fix the bugs.

The details of installing the xPack GNU Arm Embedded GCC on various platforms are presented in the separate install page.
