If RUSTFLAGS is set in the environment, Cargo will ignore rustflags
settings in its TOML configuration. So setting RUSTFLAGS=-g (like
separateDebugInfo does) to generate debug info breaks
dynamically-linked Rust packages on musl. This breakage is visible
for any packages that call into C dynamic libraries. If the binary is
linked directly to a C dynamic library, it will fail to build, and if
it depends on a Rust library which links a C dynamic library, it will
segfault at runtime when it tries to call a function from the C
library. I noticed this because pkgsMusl.crosvm is broken for this
reason, since it sets separateDebugInfo = true.
It shouldn't be possible to end up with broken binaries just by using
RUSTFLAGS to do something innocuous like enable debug info, so I think
that, even though we liked the approach of modiyfing .cargo/config
better at the time, it's become clear that it's too brittle, and we
should bite the bullet and patch the compiler instead when targetting
musl. It does not appear to be necessary to modify the compiler at
all when cross-compiling /from/ dynamically-linked Musl to another
target, so I'm only checking whether the target system is
dynamically-linked Musl when deciding whether to make the modification
to the compiler.

Nixpkgs is a collection of over 80,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community
- NixOS homepage - the NixOS.org website
- hydra - our continuous integration system
- NixOS Artwork - NixOS artwork
Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 22.11 release
- Tests for unstable/master
- Tests for the NixOS 22.11 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests. When pull requests are made, our tooling automation bot, OfBorg will perform various checks to help ensure expression quality.
The Nixpkgs maintainers are people who have assigned themselves to maintain specific individual packages. We encourage people who care about a package to assign themselves as a maintainer. When a pull request is made against a package, OfBorg will notify the appropriate maintainer(s). The Nixpkgs committers are people who have been given permission to merge.
Most contributions are based on and merged into these branches:
masteris the main branch where all small contributions gostagingis branched from master, changes that have a big impact on Hydra builds go to this branchstaging-nextis branched from staging and only fixes to stabilize and security fixes with a big impact on Hydra builds should be contributed to this branch. This branch is merged into master when deemed of sufficiently high quality
For more information about contributing to the project, please visit the contributing page.
Donations
The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
You can donate to the NixOS foundation through SEPA bank transfers or by using Open Collective:
