mysql - 无法在 NixOS 上构建 haskell 包 mysql

Question

我正在尝试使用 构建最基本的 haskell 项目cabal-3.2.0.0，ghc-8.2.2该项目使用mysql-0.1.7.3.

我使用cabal init添加mysql ^>= 0.1.7到.cabal文件中来设置项目。然后我还添加了这个shell.nix文件以将库依赖项纳入范围：

所以我添加了一个shell.nix文件来明确地将所有内容纳入范围：（这是从这里派生的）

let 
    oldpkgs=import (fetchTarball https://github.com/NixOS/nixpkgs/archive/83b35508c6491103cd16a796758e07417a28698b.tar.gz) {};
    pkgs=import <nixpkgs>{};
    ghc = oldpkgs.haskell.compiler.ghc822;
in pkgs.haskell.lib.buildStackProject {
    inherit ghc;
    name = "myEnv";
    buildInputs = (with oldpkgs; [ zlib mysql openssl ]);
}

我进入nix-shell并尝试使用cabal build --with-compiler ghc-8.2.2. 但是，我得到了这个错误而不是构建成功：

[...]

（所以实际上找到了库）

用于构建部分 mysql 库的命令是这样的：（标记为更好的可读性）

假设它与链接和 nixos 的非 FHS 一致性有关，我将其添加到文件中的可执行.cabal文件中：

extra-lib-dirs: /nix/store/6kl22pij3n5qppcmlg3a6m8ny19yylqj-mariadb-10.2.1/include/server
extra-libraries: mysql

构建结果没有变化。

这是我的完整.cabal文件：

cabal-version:      2.4
name:               mysqlTest
version:            0.1.0.0

executable mysqlTest
    main-is:          Main.hs
    build-depends: base         >= 4.9 && < 4.13
                 , mysql       ^>= 0.1.7

    hs-source-dirs:   app
    default-language: Haskell2010
    extra-lib-dirs: /nix/store/6kl22pij3n5qppcmlg3a6m8ny19yylqj-mariadb-10.2.1/include/server -- (from `which mysql` in `nix-shell`)
    extra-libraries: mysql

我还尝试将库包含在LIBRARY_PATH=[path/to/nix/store/mysql/lib]:$LIBRARY_PATH cabal build --with-compiler ghc-8.2.2（从这里）

并通过cabal 文件将文件复制mysql.h到[cabal-project/libs]并包含在其中；但是，行为也没有任何改变extra-lib-dirsextra-include-dirs

因为这是一个更大的项目的一部分，所以我需要使用它ghc-8.2.2并cabal作为构建工具。这是否需要一些调整nix-ld（如果需要如何调整？）还是有更简单的解决方案？
