🌐 Web query:

Does nixpkgs support riscv64-linux platform and are Node.js packages available for it?

💡 Result:

Yes, nixpkgs supports the riscv64-linux platform at a basic level, with stdenv bootstrapping and platform definitions in lib/systems. It is listed in flake-systems.nix as a supported system and examples.nix defines riscv64-linux. However, NixOS has no official support for riscv64-linux on nixpkgs-unstable or stable channels, and there is no official Hydra binary cache (community caches like cache.ztier.in exist for unstable). Builds are possible but often fail for many packages, including coreutils and nodejs. Node.js packages are defined generically in nixpkgs and can be built for riscv64-linux in principle (nodejs.nix uses stdenv.hostPlatform.node.arch, which supports riscv64 per Node.js BUILDING.md listing riscv64 as experimental). However, native builds fail (Issue #374456 open as of 2025, brotli compilation error), and no prebuilt binaries are available in official caches. Users may need third-party builds or cross-compilation.

Remove riscv64-linux from supportedSystems or conditionally exclude its derivatives.

Adding riscv64-linux to supportedSystems will cause flake evaluation to fail for this platform. While nixpkgs defines riscv64-linux in its platform registry, NixOS has no official support for it on nixpkgs-unstable or stable channels, and there is no official binary cache. Critically, Node.js native builds fail for riscv64-linux due to an unresolved brotli compilation error (nixpkgs issue #374456), and no prebuilt binaries are available. The flake's formatter and devShells outputs will not be evaluable for this platform without third-party or cross-compilation workarounds that are not in place here.

In `@flake.nix` at line 17, The flake's supportedSystems list currently includes
"riscv64-linux", which causes evaluation failures; update the supportedSystems
declaration in flake.nix to remove "riscv64-linux" or wrap the list with a
conditional/filter to exclude riscv64 variants (e.g., use builtins.filter or a
small predicate) so that outputs like formatter and devShells are not evaluated
for riscv64-linux; locate the supportedSystems symbol in flake.nix and either
delete the "riscv64-linux" entry or modify the expression to exclude entries
that match "riscv64-linux" before exporting.
