What changed:
* Fixed crtbeginS.o and crtendS.o missing
(they may or may not be called crt{begin_end},{,_shared}.
* Fixed implicit function declaration causing build errors for various
builds by supplying -Wno-implicit-function-declaration.
* Fixed __cxxabi_config.h missing, by adding -I${cxxabi}/include/c++/v1
in the wrapper.
* Fixed libcxx failing to build due to missing libunwind symbols by
including libunwind as a buildInput, and setting
-DLIBCXX_ADDITIONAL_LIBRARIES=unwind for stdenv.hostPlatform.useLLVM == true.
* libcxxabi wants to find libunwind at libunwind_shared.so, so symlink
it there in libunwind.
* llvmPackages_16.libcxxabi: Pass -nostdlib via CMAKE_*_LINKER_FLAGS
Without this flag, the link of libcxxabi.so tries to pull in libgcc and
friends, from the clang compiler driver.
* Drop unneeded musl hack patch from libcxx.
* Pass -Wno-error=implicit-function-declaration only to compiler-rt
See LLVM forum discussion:
https://discourse.llvm.org/t/configure-script-breakage-with-the-new-werror-implicit-function-declaration/65213
In summary, LLVM 16 made implicit function declaration an error. This
happens a lot in configure scripts which can break things.
* llvmPackages_16: !isDarwin: Supply -DLIBCXX_ABI_USE_LLVM_UNWINDER=On
Otherwise it fails with various undefined references to _Unwind_*
functions: (full list: _Unwind_DeleteException _Unwind_GetIP
_Unwind_GetLanguageSpecificData _Unwind_GetRegionStart
_Unwind_RaiseException _Unwind_Resume _Unwind_SetGR _Unwind_SetIP).
* 16.libcxxabi: Only pass -nostdlib for useLLVM and Darwin builds
What was tested:
* x86_64-linux, aarch64-linux, the stdenv builds.
* Additionally I was able to get nix to build, with an overlay to fix
a couple of minor issues in downstream packages (overlay supplied in
PR #246577.
* aarch64-darwin fails spuriously in a single LLVM test
strip-preserve-atime.test checking atime timestamps.
* The same for pkgsLLVM with llvmPackages = llvmPackages_15.

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 23.05 release
- Tests for unstable/master
- Tests for the NixOS 23.05 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.
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:
