* Switch to default buildPhase & installPhase
* In preConfigure
* Do not add -DNPARTITION to CHOLMOD_CONFIG. That would disable the use of Metis but we already have that.
* Do not remove -lrt on Darwin, Darwin compiler can handle that and the code no longer exists anyway.
* With CUDA enabled
* Do not replace CUDA_ROOT. It does not exist any more. Instead we are setting CUDA_PATH in makeFlags.
* Do not replace GPU_BLAS_PATH, it defaults to CUDA_PATH so it will end up with the same value.
* Do not add -DCHOLMOD_OMP_NUM_THREADS to GPU_CONFIG. Why would be having the library use the same number of threads as the builder a good idea?
* Do not replace CUDA_PATH, we are setting it in makeFlags now.
* Do not replace CUDART_LIB and CUBLAS_LIB. They were being replaced incorrectly (cuda libs are located in lib directory, not lib64). Instead set the correct paths in makeFlags.
* Do not replace CUDA_INC_PATH. Its default looks like it will end up with the same value.
* Do not replace NV20, NV30, NV35 – not used any more.
* Do not replace NVCC, defaults to the same.
* Do not replace NVCCFLAGS, we just used the default from SourceSparse 4.4.7 with -gencode=arch=compute_60,code=compute_60 tacked on top. Current upstream default looks much better.
* Stop adding -DNTIMER to CFLAGS on Darwin – clock_gettime is supported by macOS 10.12 SDK.
* In buildPhase
* Move the make arguments to makeFlags and library to buildFlags, allowing us to drop the manual make call. I did not verify all of these are still needed.
* Remove the creation of libsuitesparse.so. As far as I could tell it is some kind of remnant of our old expression – perhaps due to past deficiencies of the build scripts, we created the individual libraries as symlinks to libsuitesparse.so:

Nixpkgs is a collection of over 40,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.
Manuals

- Nixpkgs Manual - contributing to Nixpkgs and using programming-language-specific Nix expressions
- Nix Package Manager Manual - how to write Nix expressions (programs), and how to use Nix command line tools

- Community-maintained list of ways to get in touch (Discord, Matrix, Telegram, other IRC channels, etc.)
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
- 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 19.09 release
- Tests for unstable/master
- Tests for the NixOS 19.09 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 over 40,000 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:
master
is the main branch where all small contributions gostaging
is branched from master, changes that have a big impact on Hydra builds go to this branchstaging-next
is 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.
