# Genode Packages

This repo contains Nix expressions for building Genode with Nixpkgs and building
|
|
|
|
|
Nixpkgs for Genode. At the moment the former is experimental and broken in many
|
|
|
|
|
cases, the later is probably broken for all cases.

Furthermore, this repository is structured as a Nix flake, with is in itself an
|
|
|
|
|
experimental extension of the Nix utility. The flakes capable `nix` frontend is
|
|
|
|
|
available from Nixpkgs as `nixFlakes`. It is possible to bootstrap to flakes by
|
|
|
|
|
installing Nix on a standard Linux distro, followed by `nix-env -i nixFlakes`.
|
|
|
|
|
Flakes are available from NixOS using the following expression:
|
|
|
|
|
`{ pkgs, ... }: { nix.package = pkgs.nixFlakes; }`

The LLVM cross-compiler may useful already, Clang apparently builds trivial
|
|
|
|
|
Genode componenents without serious problems. Bootstrapping GCC is not practical
|
|
|
|
|
due to the recursive autotools build system.

The compiler environment for x86_64 should be accessible from the `stdenv` at
|
|
|
|
|
the path `.#packages.x86_64-linux-x86_64-genode.stdenv`. There is currently no
|
|
|
|
|
recommendations for integrating the compiler within external build systems.

Bootstrapping the LLVM toolchain on a laptop can take hours, so personally I
|
|
|
|
|
farm out the builds. If you interested in binaries please contact me and we can
|
|
|
|
|
setup a cache.
