我正在尝试将 libraw 编译为我的 node.js 项目的依赖项。

我有两个不同的 .gyp 文件：./binding.gyp和./vendor/raw.gyp

我已经下载了当前版本的 libraw 和去马赛克包，它们都可以在以下./vendor/文件夹中找到：

LibRaw-0.17.1
LibRaw-demosaic-pack-GPL2-0.17.1
LibRaw-demosaic-pack-GPL3-0.17.1

这是我的两个 gyp 文件：

./binding.gyp

{
  "includes": [ "vendor/raw.gyp" ],
  "targets": [
    {
      "target_name": "node_libraw",
      "sources": [ "node_libraw.cc" ],
      "include_dirs" : [
        "build/Release",
        "vendor/LibRaw-0.17.1",
        "<!(node -e \"require('nan')\")"
      ],
      "libraries": [
        "-lraw",
        "-Wl,-rpath=./build/Release/obj.target/"
      ]
    }
  ],
}

./vendor/raw.gyp

{
  "targets": [
    {
      "default_configuration": "Release",
      "target_name": "raw",
      "type": "static_library",
      "sources": [
        "LibRaw-0.17.1/internal/dcraw_common.cpp",
        "LibRaw-0.17.1/internal/dcraw_fileio.cpp",
        "LibRaw-0.17.1/internal/demosaic_packs.cpp",
        "LibRaw-0.17.1/src/libraw_cxx.cpp",
        "LibRaw-0.17.1/src/libraw_datastream.cpp",
        "LibRaw-0.17.1/src/libraw_c_api.cpp"
      ],
      "include_dirs": [ 
        "./LibRaw-demosaic-pack-GPL2-0.17.1",
        "./LibRaw-demosaic-pack-GPL3-0.17.1",
        "./LibRaw-0.17.1"
      ],
      "libraries": [
        "-ljpeg8"
      ],
      "cflags": [ 
        "-Wdeprecated-declarations",
        "-pthread -w"
      ],
      "cflags_cc": [
        "-pthread -w",
        "-fexceptions",
        "-I./LibRaw-demosaic-pack-GPL2-0.17.1",
        "-DLIBRAW_DEMOSAIC_PACK_GPL2",
        "-I./LibRaw-demosaic-pack-GPL3-0.17.1",
        "-DLIBRAW_DEMOSAIC_PACK_GPL3",
        "-DUSE_JPEG8"
      ]
    }
  ]
}

问题是，当我尝试编译库时，node-gyp configure build最终出现以下错误：

/usr/bin/ld: cannot find -lraw
collect2: error: ld returned 1 exit status
node_libraw.target.mk:124: recipe for target 'Release/obj.target/node_libraw.node' failed

这是完整的输出：
