无法在堆栈项目中使用 nix 构建 hzk（haskell zookeeper）

Question

我正在尝试将我雇主的大型 haskell 堆栈项目移植到 nix 并且它正在对zookeeper_mt进行吐槽。 在 stack.yaml 中，我启用了 nix 构建并且已经添加了一些像 zlib 这样的 nix 包来解决构建错误，但即使使用 zookeeper_mt，我也得到：

hzk                             > configure
hzk                             > Configuring hzk-2.1.0...

我可以在nix-shell -p zookeeper_mt中看到 zookeeper.h 以${zookeeper}/include/zookeeper/结尾，但这就像 ubuntu package 也有 /usr/include 的这个 zookeeper 子目录，以及在安装了 ubuntu package 的非 nix 堆栈构建中很好。

我在该错误消息中看到-I/nix/store/grng8b5wmrppx2rmcsqkmjyq23bj1j38-zookeeper_mt-3.4.13/include没有额外的/zookeeper但我不确定系统的哪一部分对此负责或如何修复它因为我'我对尼克斯很陌生。 是nix包的错，堆栈的错还是别的什么？

Answer 1

hzk.cabal有这样的行

  include-dirs:        /usr/include/zookeeper

这对于符合 FHS 的系统来说是一个很好的帮助，只要系统分发包含 zookeeper 库。 /usr/local或/opt/*中的本地安装将导致相同的问题。

Nixpkgs 像这样解决它https://github.com/NixOS/nixpkgs/blob/a8a0dfa047d9a96f832ff2be30d004ad5544bd7e/pkgs/development/haskell-modules/configuration-nix.nix#L1017-L12

为了让它在堆栈中工作，我们可以使用它的 nix-shell 集成。

stack.yaml ：

nix:
  packages: [] # Note that specifying both packages: and a shell-file: results in an error.
  shell-file: stack-shell.nix

stack-shell.nix ：

{ghc}:
let pkgs = import <nixpkgs> {};
# (side note)
# If you're pinning nixpkgs, You should probably set
# NIX_PATH=nixpkgs=... in your real `shell.nix`
# because that's where stack gets its ghc.
in
pkgs.haskell.lib.buildStackProject {
  inherit ghc;
  name = "myEnv";
  buildInputs = [ pkgs.zookeeper_mt ];
  shellHook = ''
    NIX_CFLAGS_COMPILE="-I ${pkgs.zookeeper_mt}/include/zookeeper $NIX_CFLAGS_COMPILE"
  '';
}
