The easy part is to add NIX_CFLAGS_COMPILE for "regular" libraries. A bit more tricky is to add the required flags for libclang to find libstdcxx. For this we parse arguments to bindgen to look for -x c++ or -xc++ and if found add NIX_CXXSTDLIB_COMPILE to the arguments. This variable is populated by a complex dance of setupHooks. We trigger this by adding clang to propagatedBuildInputs. A more subtle way may exist.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.03
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
