Only binaries for Windows are provided.

They were built with mingw-w64, and run on any reasonably recent i686 and x86_64 Windows machines.

Instructions on how to install the binaries are available in the How to install the Windows Build Tools? page.

The build tools are also available as an xPack and can be conveniently installed with xpm:

xpm install --global @gnu-mcu-eclipse/windows-build-tools

This installs the latest available version.

For better control and repeatability, the build scripts use Docker containers; all files required during builds are available as a separate gnu-mcu-eclipse/windows-build-tools project.
