The OpenMW codebase already has Darwin build support within it, so porting it over to nixpkgs was something I wanted to try out. Issues encountered, in order: A few dependencies in nixpkgs were missing Darwin support. Details of those changes are in their respective commits. After the dependencies were building, the build first failed with a missing reference to VideoDecodeAcceleration, which was easily dealt with. Then the build succeeded! Job's done, success! Except OpenMW.app was nowhere to be found in the result folder. OpenMW-CS.app, however, was produced and appeared to be running correctly (though I will admit I didn't test it very much as I'm not very familiar). Going through OpenMW's CMakeLists.txt showed that a CMake define was needed, `OPENMW_OSX_DEPLOYMENT=ON`. This is what enables OpenMW.app to be built. Once the define was added, the build began to fail with missing plugins to OpenSceneGraph. Looking into that showed that OSG doesn't build certain plugins on Darwin due to the fact that their functionality is replicated by built- in system libraries. To save space, these libraries are not built on Darwin. OpenMW, however, requires these libraries to exist. I was familiar with the process of building OpenMW on Darwin already, due to having built it locally ahead of time, so I remembered that the OpenMW folks have a separate repository with Mac-specific patches. One of those patches is to OpenSceneGraph for this exact issue, which is now applied here. The next error was caused by `fixup_bundle` running from the OpenMW CMakeLists.txt, which appears to be broken in Darwin under Nix. Searching nixpkgs shows that others have worked around the issue by removing the call to `fixup_bundle` completely. At this point, the build passed and OpenMW.app was created and was executable! After the intro video played, it was clear that something wasn't working though. Every texture was completely pink, navigating the main menu was impossible. Looking at the console output showed that OpenSceneGraph was attempting to load dds textures, but the plugin for doing so could not be loaded. I looked at the plugin with `file` which showed the file was actually a bash script. It was setting some QT environment variables before calling the real plugin executable. I resolved this issue with setting `dontWrapQtApps`, as everything seems to work without it (even the QT-based apps like the Construction Set). |

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:
