c++ - 使用 boost(或与此相关的任何其他库)构建 NodeJs 模块

Question

我正在尝试使用一些 boost header 使用 C++ 和 Ubuntu 13.04 构建一个 nodejs 模块，如下所示:

#include <iostream>
#include <string>
#include <node/node.h>
#include <v8.h>
#include <boost/lexical_cast.hpp>



using namespace std;
using namespace v8;


Handle<Value> Method(const Arguments& args) {
  HandleScope scope;

  std::string foobar = "8";

  return scope.Close(String::New("world"));
}

void init(Handle<Object> exports){

    exports->Set(String::NewSymbol("Hello"),
            FunctionTemplate::New(Method)->GetFunction());

}

NODE_MODULE(hello, init)

但是，当使用 node-gyp 编译时，出现以下错误:

sam@ubuntu:~/workspace_cpp/NodeTest/src$ node-gyp build gyp info it worked if it ends with ok gyp info using node-gyp@0.10.9 gyp info using node@0.10.15 | linux | x64 gyp info spawn make gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ] make: Entering directory /home/sam/workspace_cpp/NodeTest/src/build' CXX(target)

我在网上找不到任何有关如何让 node-gyp 与其他库(如 boost)一起构建的内容。有人对此有任何见解或经验吗？我的最终目标是使用 gsoap 制作一个 SOAP 模块。

编辑我假设我必须以某种方式编辑我的 binding.gyp 文件以允许编译 boost。该文件目前看起来像这样:

{   "targets": [
    {
      "target_name": "hello",
      "sources": [ "NodeTest.cpp" ]
    }   ] }

对于出现此错误的任何其他人，关键是为 node-gyp 启用异常。在您的 bindings.gyp 文件中，确保包含此内容

...
'cflags!': [ '-fno-exceptions' ],
'cflags_cc!': [ '-fno-exceptions' ]
...
