Developer & maintainer pages:


The xPack GNU Arm Embedded GCC is an alternate binary distribution that complements the official GNU Arm Embedded Toolchain maintained by Arm.


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 (Windows 64/32-bit, GNU/Linux 64/32-bit, macOS)
  • 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.


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.


The xPack GNU Arm Embedded GCC distribution includes the standard GCC documentation, in info, man and pdf format; it is located in the share/doc folder, for example the pdf files are:
