Nix Flake构建YASMIN C++库时遇CMake路径错误

问题背景 #

使用Nix Flake开发C++项目，引入YASMIN状态机库，构建时遇到CMake错误，提示找不到CMakeLists.txt。

原flake配置：

{
  description = "flake for an autonomous rover";

  inputs = {

    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";

    flake-utils.url = "github:numtide/flake-utils";

  };

  outputs = { self, nixpkgs , flake-utils }:
    flake-utils.lib.eachDefaultSystem (system: 
    let pkgs = nixpkgs.legacyPackages.${system};
    in rec {

      packages.yasmin = with pkgs;
        stdenv.mkDerivation {
          name = "yasmin";
          src = fetchFromGitHub {
            owner = "uleroboticsgroup";
            repo = "yasmin";
            rev = "073e5e33cf2f29d42a1d7dcb3fe737390cfcb3a2"; # v3.3.0
            sha256 = "sha256-fcTP8Xa2W8K4TBmmwMk3zgU9ISH/MP87GxLl4Xnt0Xc=";
          };
          buildInputs = [ cmake ];
          buidlPhase = ''
            mkdir build && cd build 
            cmake ../yasmin/ -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_INSTALL_PREFIX=$out
          '';
          installPhase = ''
            make install
          '';
        };

      devShells.default =
        pkgs.mkShell { packages = with pkgs; [ cmake packages.yasmin ]; };

    });
}

错误原因分析 #

1. 拼写错误：配置中buidlPhase是拼写错误，正确应为buildPhase，导致自定义构建步骤未执行，默认的configurePhase被触发。
2. 默认阶段未跳过：stdenv.mkDerivation默认会执行configurePhase，如果自定义构建流程，需要显式禁用该阶段。
3. 源码路径错误：YASMIN仓库解压后根目录直接包含CMakeLists.txt，不需要指定../yasmin/，该路径不存在导致CMake找不到文件。

修复方案 #

• 修正buidlPhase为buildPhase
• 添加configurePhase = "";跳过默认配置阶段
• 调整CMake命令的源码路径为../（因为build目录创建在源码根目录下，上级目录就是源码根）
• 规范依赖位置：将cmake移至nativeBuildInputs（构建依赖放在此处更符合Nix惯例）

修正后的完整配置 #

{
  description = "flake for an autonomous rover";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs , flake-utils }:
    flake-utils.lib.eachDefaultSystem (system: 
    let pkgs = nixpkgs.legacyPackages.${system};
    in rec {

      packages.yasmin = with pkgs;
        stdenv.mkDerivation {
          name = "yasmin";
          src = fetchFromGitHub {
            owner = "uleroboticsgroup";
            repo = "yasmin";
            rev = "073e5e33cf2f29d42a1d7dcb3fe737390cfcb3a2"; # v3.3.0
            sha256 = "sha256-fcTP8Xa2W8K4TBmmwMk3zgU9ISH/MP87GxLl4Xnt0Xc=";
          };
          nativeBuildInputs = [ cmake ];
          configurePhase = "";
          buildPhase = ''
            mkdir build && cd build 
            cmake ../ -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_INSTALL_PREFIX=$out
          '';
          installPhase = ''
            make install
          '';
        };

      devShells.default =
        pkgs.mkShell { packages = with pkgs; [ cmake packages.yasmin ]; };

    });
}
