=== Run binaries of different architecture === | |||
Following configuration will enable the emulation of different architectures. For example to run aarch64 and riscv64 binaries on an native x86_64 host, add following part to your system configuration, apply it and reboot your system.<syntaxhighlight lang="nix"> | |||
boot.binfmt.emulatedSystems = [ | |||
"aarch64-linux" | |||
"riscv64-linux" | |||
