As you may not have access to actual hardware platforms, we +recommend using the @code{qemu-binfmt-service-type} to emulate them. In +order to enable it, add the following service to the list of services in +your @code{operating-system} configuration: + +@example +(service qemu-binfmt-service-type + (qemu-binfmt-configuration + (platforms (lookup-qemu-platforms "arm" "aarch64" "ppc" "mips64el")) + (guix-support? #t))) +@end example + +Then reconfigure your system. + +You can then build packages for different platforms by specifying the +@code{--system} option. For example, to build the "hello" package for +the armhf, aarch64, powerpc, or mips64 architectures, you would run the +following commands, respectively: +@example +guix build --system=armhf-linux --rounds=2 hello +guix build --system=aarch64-linux --rounds=2 hello +guix build --system=powerpc-linux --rounds=2 hello +guix build --system=mips64el-linux --rounds=2 hello +@end example + +@item @cindex bundling Make sure the package does not use bundled copies of software already available as separate packages. |
