在node.js模塊中使用node-gyp鏈接增強

Question

我試圖創建一個node.js加載項，它是一個簡單的包裝來訪問Boost庫項目中的perl正則表達式。

我正在運行OSX 10.9.2，而且我也不是一個C++開發人員，所以這個工具並不熟悉。

我的項目如下所示

boost.cc

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

#include <boost/regex.hpp> 

using namespace v8; 

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

    if (args.Length() < 2) { 
    ThrowException(Exception::TypeError(String::New("Wrong number of arguments"))); 
    return scope.Close(Undefined()); 
    } 

    if (!args[0]->IsString()) 
    { 
    ThrowException(Exception::TypeError(String::New("Regex agrument 1 must be a string"))); 
    return scope.Close(Undefined()); 
    } 

    if (!args[1]->IsString()) 
    { 
    ThrowException(Exception::TypeError(String::New("Target agrument 2 must be a string"))); 
    return scope.Close(Undefined()); 
    } 

    v8::String::Utf8Value param0(args[0]->ToString()); 
    v8::String::Utf8Value param1(args[1]->ToString()); 

    std::string sre = std::string(*param0); 
    std::string s = std::string(*param1); 

    try 
    { 
    boost::cmatch matches; 
    boost::regex re(sre, boost::regex::icase); 

    if (boost::regex_match(s.c_str(), matches, re)) 
    { 
     return scope.Close(Boolean::New(true)); 
    } 
    else 
    { 
     return scope.Close(Boolean::New(false)); 
    } 
    } 
    catch (boost::regex_error& e) 
    { 
    ThrowException(Exception::TypeError(String::New("Regex is not a valid regular expression"))); 
    return scope.Close(Undefined()); 
    } 

    return scope.Close(Boolean::New(false)); 
} 

void init(Handle<Object> exports) { 
    exports->Set(String::NewSymbol("match"), 
     FunctionTemplate::New(Match)->GetFunction()); 
} 

NODE_MODULE(boost, init) 

binding.gyp

{ 
    "targets": [ 
    { 
     "target_name": "boost", 
     "sources": [ "boost.cc" ], 
     "include_dirs": [ 
       "/usr/local/include/boost", 
      ], 
      "libraries": [ 
       "/usr/local/lib/libboost_regex.dylib" 
      ] 
     } 
    ] 
} 

app.coffee

addon = require('../addons/boost/build/Release/boost') 
console.log(addon.match("(?<!street)name", "StreetName")) 

正在運行node-gyp rebuild --verbose導致加載項的成功構建。當運行應用程序，雖然我收到以下錯誤：

dyld: lazy symbol binding failed: Symbol not found: __ZN5boost9re_detail12perl_matcherIPKcSaINS_9sub_matchIS3_EEENS_12regex_traitsIcNS_16cpp_regex_traitsIcEEEEE14construct_initERKNS_11basic_regexIcSA_EENS_15regex_constants12_match_flagsE 
    Referenced from: <projects dir>/addons/boost/build/Release/boost.node 
    Expected in: dynamic lookup

    Referenced from: <projects dir>/addons/boost/build/Release/boost.node 
    Expected in: dynamic lookup 

我與binding.gyp各地發揮和otool了幾個小時，但我清楚我的深度這裏。

otool對輸出給了我如下：

otool -L build/Release/boost.node 
build/Release/boost.node: 
    /usr/local/lib/libboost_regex.dylib (compatibility version 0.0.0, current version 0.0.0) 
    /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 60.0.0) 
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1) 
    /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 2577.0.0) 

我安裝了BREW Boost庫（BREW安裝--without-python的提升）和所有的動態庫似乎在那裏。

我的問題，我猜是類似於這個：node-gyp on OSX 10.7.5 -- dyld: lazy symbol binding failed: Symbol not found - 但我沒有運氣的修復。

我可以得到一個基本的附加不依賴運行，它只是出現使用節點GYP等

任何幫助，將不勝感激，我無法正常鏈接升壓庫！

答案是使用C++ 11編譯節點附加組件。 bind.gyp的一些調整是所有必需的。

binding.gyp

    "targets": [ 
    { 
     "target_name": "boost", 
     "sources": [ "boost.cc" ],

       "/usr/local/include/boost", 
      ], 
      "libraries": [ 
       "/usr/local/lib/libboost_regex.dylib" 
      ], 
      "cflags_cc!": [ "-fno-rtti", "-fno-exceptions" ], 
      "cflags!": [ "-fno-exceptions" ], 
      "conditions": [

         'MACOSX_DEPLOYMENT_TARGET': '10.7', 
         'GCC_ENABLE_CPP_EXCEPTIONS': 'YES' 
        } 
       }] 
      ] 
     } 
    ] 
}
