How to use mixed C++ & .Net dll in node.js? (Error: abort() has been called)

Question

我想在 Visual Studio 2015 年使用包含 C++ 和 C# 代码的 dll 创建本机节点扩展。我无法在去年的 my own instructions 之后使用它，它基于最新的 node-gyp.

当不使用 /clr 选项时，我可以运行像下面这样的程序。

console.log("1");
const addon = require('./build/Release/addon');
console.log("2");

启用/clr 时，只会执行对日志的第一次调用。在调试模式下编译 dll 时，我收到以下消息：

如何修复/调试此问题？

（我知道有优势，但我正在尝试采用 node-gyp 方式）

Answer 1

在 VS2015 中尝试所有（？）编译器和链接器选项失败后，我找到了如何设置我的 binding.gyp，以使 .Net 正常工作：

{
  "targets": [
    {
      "target_name": "addon",
      "sources": [ "hello.cc" ],
      "msbuild_settings": {
        "ClCompile": {
          "CompileAsManaged": "true",
          "ExceptionHandling": "Async",
        },
      },
    }
  ]
}

我通过成功执行以下托管和非托管代码的组合来验证构建：

#include <node.h>
#include <v8.h>

namespace demo {

  #pragma managed

  void callManaged()
  {
    System::String^ result = gcnew System::String("hola");
    System::Console::WriteLine("It works: " + result);
  }

  #pragma unmanaged

  using v8::FunctionCallbackInfo;
  using v8::Isolate;
  using v8::Local;
  using v8::Object;
  using v8::String;
  using v8::Value;

  void Method(const FunctionCallbackInfo<Value>& args) {
    Isolate* isolate = args.GetIsolate();
    callManaged();
    args.GetReturnValue().Set(String::NewFromUtf8(isolate, "woooooorld"));
  }

  void init(Local<Object> exports) {
    NODE_SET_METHOD(exports, "hello", Method);
  }

  NODE_MODULE(addon, init)

}

除非真的必须使用 node-gyp，否则现在 cmake-js 和 node-addon-api（提供 ABI，因此您无需为新的 Node.js 版本重建) 应该被使用。 CMakeLists.txt for cmake-js 编译混合 native/managed 代码：

cmake_minimum_required(VERSION 2.8)

project (my-addon)
set(SOURCE_FILES src/main.cc)
add_library(${PROJECT_NAME} SHARED ${SOURCE_FILES})
set_target_properties(${PROJECT_NAME} PROPERTIES 
  PREFIX ""
  SUFFIX ".node"
  COMMON_LANGUAGE_RUNTIME "") # "pure" and "safe" unsupported in VS 2017
target_include_directories(${PROJECT_NAME}
  PRIVATE ${CMAKE_SOURCE_DIR}/node_modules/node-addon-api
  PRIVATE ${CMAKE_JS_INC})
target_link_libraries(${PROJECT_NAME} ${CMAKE_JS_LIB})

从一个package.json开始

{
  "name": "my-addon",
  "version": "1.0.0",
  "description": "My node.js addon",
  "main": "main.js",
  "scripts": {
    "test": "node main.js",
    "install": "cmake-js compile"
  }
}

main.js 喜欢

var addon = require('bindings')('my-addon');
console.log("hello: " + addon.doSomething());

一个src/main.cc喜欢

#include <napi.h>

namespace myaddon
{
  #pragma managed

  void callManaged()
  {
    System::String^ result = gcnew System::String("hola");
    System::Console::WriteLine("It works: " + result);
  }

  #pragma unmanaged

  Napi::String MyMethod(const Napi::CallbackInfo& info) {
    Napi::Env env = info.Env();
    callManaged();
    return Napi::String::New(env, "world");
  }

  Napi::Object Init(Napi::Env env, Napi::Object exports) {
    exports.Set(Napi::String::New(env, "doSomething"),
                Napi::Function::New(env, MyMethod));
    return exports;
  }

  NODE_API_MODULE(myaddon, Init)
}

建造，运行

npm install bindings
npm install node-addon-api
npm install cmake-js
npm install

要执行，运行

npm test
