I am working on a project that uses stereolab's depth camera ZED to retrieve distance of obstacles. Its SDK is written in C++ and it requires CUDA 6.5. However, I have to integrate this program with another part of project, which is written in nodejs. So I decided to compile ZED code as a node module. I've gone through node addon tutorial. Now I've written the interface, but I got following error after trying to build the project using command "node-gyp configure build". It seems the 'zed' module wasn't built. I have no idea what this error is and I've searched nothing so far. Can someone please give me some directions? Thank you.

This is my binding.gyp:

{
  "targets": [
    {
      "target_name": "zed",
      "sources": [
        "../src/main.cpp",
      ],
      "include_dirs": [
        "/usr/local/zed/include/",
        "/usr/local/cuda-6.5/include/",
        "../include/"
      ],
    }
  ]
}

This is my package.json:

{
  "name": "zed_depth_viewer",
  "version": "0.0.0",
  "description": "Measure depth with zed sdk",
  "main": "zed_depth.js",
  "private": true,
  "gypfile": true,
  "dependencies": {
    "bindings": "~1.2.1"
  }
}

And following is basically my interface with node: (just started for testing, 'initProgram' is working as 'main' for the project)

void node_main_handle(const FunctionCallbackInfo<Value>& args) {
  Isolate* isolate = Isolate::GetCurrent();
  HandleScope scope(isolate);

  Local<FunctionTemplate> tpl = FunctionTemplate::New(isolate, initProgram);
  Local<Function> fn = tpl->GetFunction();

  // omit this to make it anonymous
  fn->SetName(String::NewFromUtf8(isolate, "initProgram"));

  args.GetReturnValue().Set(fn);
}

void Init(Handle<Object> exports, Handle<Object> module)
{
    NODE_SET_METHOD(module, "exports", node_main_handle);
}

NODE_MODULE(zed, Init)

An example using this module should be:

var zed = require('bindings')('zed'); //zed.node will be in './build/Release/'
var func = zed();
func();

Not sure if this works, haven't tested it yet. I'm new to nodejs.

从这条线上似乎/bin/sh: 1: -DNODE_GYP_MODULE_NAME=zed: not found找不到编译器（它应该类似于/usr/bin/g++而不是/bin/sh）。如果你想将自定义标志传递给 gyp 或者如果你想要一个特定的编译器，你的 gyp 文件应该是这样的：

{
  'make_global_settings': [
     ['CXX','/usr/bin/clang++-3.5'],
     ['LINK','/usr/bin/clang++-3.5'],
  ],
  "targets": [
    {
      "target_name": "zed",
      "sources": [
        "../src/main.cpp",
      ],
      "include_dirs": [
        "/usr/local/zed/include/",
        "/usr/local/cuda-6.5/include/",
        "../include/"
      ],
      "link_settings": {
        "libraries": [ // For compiler
          "-requiredlibs",
        ],
        "ldflags": [  // For linker
            "-L</path/to/libs",
            "-Wl,-rpath,path/to/libs",
        ]
      },
      "cflags": [
        "-std=c++11"
      ],
    }
  ]
}

上面的 gyp 文件使用clang（而不是g++）进行编译和链接，并rpath为创建的共享库设置正确的值，因此您无需在每次要使用绑定时都导出库路径！

有关更多信息，这篇文章可能有用！
