15.1 platform Reference

The platform data type describes a platform: an ISA (instruction set architecture), combined with an operating system and possibly additional system-wide settings such as the ABI (application binary interface).

Data Type: platform

This is the data type representing a platform.

target

This field specifies the platform’s GNU triplet as a string (see GNU configuration triplets in Autoconf).

system

This string is the system type as it is known to Guix and passed, for instance, to the --system option of most commands.

It usually has the form "cpu-kernel", where cpu is the target CPU and kernel the target operating system kernel.

It can be for instance "aarch64-linux" or "armhf-linux". You will encounter system types when you perform native builds (see 本地构建).

linux-architecture (default: #false)

This optional string field is only relevant if the kernel is Linux. In that case, it corresponds to the ARCH variable used when building Linux, "mips" for instance.

rust-target (default: #false)

This optional string field is used to determine which rust target is best supported by this platform. For example, the base level system targeted by armhf-linux system is closest to armv7-unknown-linux-gnueabihf.

glibc-dynamic-linker

This field is the name of the GNU C Library dynamic linker for the corresponding system, as a string. It can be "/lib/ld-linux-armhf.so.3".
