Question

我想在Node.js应用程序中使用DronecodeSDK（C ++）库。我目前无法构建包含DronecodeSDK标头的node-addon。 node-gyp找不到子子目录中的标头。

包括

#include <dronecode_sdk/dronecode_sdk.h>很好，但是没有#include <dronecode_sdk/plugins/action/action.h>。

如果我将action.h文件移动到dronecode_sdk/action.h，那么包含就可以了。只有在将其移动到插件的子目录中时，才可以找到它。

我的binding.gyp文件：

{
  "targets": [
    {
      "include_dirs" : [
            "<!(node -e \"require('nan')\")",
            "../lib/DronecodeSDK/install/include"
        ],
     "libraries": [ "../lib/DronecodeSDK/install/lib/libdronecode_sdk.a" ],
      "target_name": "DronecoreSDK",
      "sources": [ "DronecoreSDKBridge.cc" ]
    }
  ]
}

'DronecodeSDKBridge.cc'中有两个include语句：

#include <dronecode_sdk/dronecode_sdk.h>
#include <dronecode_sdk/plugins/action/action.h>

我收到以下错误消息：

是子子目录不起作用，还是其他地方出现错误？我检查了所有标头文件的文件权限是否可读。

Node-gyp路径非常神秘。

库路径../lib/DronecodeSDK/install/lib/libdronecode_sdk.a是正确的。但是，包含路径../lib/DronecodeSDK/install/include不正确。

无论如何，node-gyp都能找到dronecode_sdk.h头的原因是，它默认情况下在项目的两个最顶层目录中搜索头。

更改包含lib/DronecodeSDK/install/include的包含路径可以解决此问题。

Node-gyp构建失败。无法在包含目录的子目录中找到库头文件
