在Mac OS X上升級元組，鏈接器錯誤10.7

我在運行Mac OS X 10.7.3的MacBook Pro上從源代碼編譯了boost 1.49.0，我使用Xcode 4.3.2和Apple的LLVM 3.1作爲我的開發環境。所描述的代碼（從升壓HTTP server1的例子）在連接錯誤導致以下行：在Mac OS X上升級元組，鏈接器錯誤10.7

void Connection::handleRead(const boost::system::error_code& error, size_t bytesTransfered) { 
    if (!error) { 
     boost::tribool result; 
     boost::tie(result, boost::tuples::ignore) = requestParser.parse(request, buffer.data(), buffer.data() + bytesTransfered); 

     if (result) { 
      requestHandler.handleRequest(request, reply); 
      async_write(socket, reply.toBuffers(), boost::bind(&Connection::handleWrite, shared_from_this(), placeholders::error)); 
     } 
     else if (!result) { 
      reply = Reply::stockReply(Reply::badRequest); 
      async_write(socket, reply.toBuffers(), boost::bind(&Connection::handleWrite, shared_from_this(), placeholders::error)); 
     } 
     else { 
      socket.async_read_some(boost::asio::buffer(buffer), boost::bind(&Connection::handleRead, shared_from_this(), placeholders::error, placeholders::bytes_transferred)); 
     } 
    } 
    else if (error != error::operation_aborted) { 
     connectionManager.stop(shared_from_this()); 
    } 
}

我搜索的答案，但我無法找到與之相關的任何事情，我也不明白爲什麼錯誤發生。該項目鏈接到lboost_system。我錯過了什麼嗎？我是新來的圖書館。

事實證明我的問題不在這個方法中，我錯誤地在類實現中有RequestParser.parse（），用boost示例檢查該方法在類的聲明中實現。
