C ++ / Ada链接错误

标签： c++ linker-errors ada

我根本不熟悉链接错误所以我希望有人可以对这些错误有所了解......

我正在使用Legacy Ada计划。我正在开发一个C ++扩展，其中Ada将使用代理来调用C ++函数。 C ++干净利落地编译，没有任何警告。但是我收到以下Undefined Symbol错误：

#include "cppProxy.h"
extern classHandler *classPtr;

void processData(void* ioBuffer)
{
   classPtr->processData(ioBuffer);
}

代码库如下：

#include "classHandler.h"
extern "C" void processData(void* ioBuffer);

标题文件：

extern "C"
{
   classHandler* create()
   {
      return new classHandler;
   }
   void destroy(classHandler *p)
   {
      delete p;
   }
}

void processData(*ioBuffer)
{
   int idx;
   data = static_cast<int*>(ioBuffer);

   idx = (data[0] >> 16);
   returnData[idx] = data;
}

classHandler.cpp 

class classHandler
{
   public:
     classHandler();
     ~classHandler();

    void processData(void* ioBuffer);
};

typedef classHandler classPtr;
typedef void destroy_t(classHandler*);

classHandler.h 

<?php $x = $_GET['house_id']; ?>
<?php include 'connection.php';?>
<?php
$queryz = "SELECT * FROM photos WHERE id = $x";
$link = mysqli_query($conn, $queryz);
$lattitude = "SELECT latitude FROM location WHERE id=$x";
$lt = mysqli_query($conn,$lattitude) ;
$longitude = "SELECT longitude FROM location WHERE id=$x";
$lg = mysqli_query($conn,$longitude) ;
?>

<?php

    include 'connection.php';

    // Create connection


    $queryz = "SELECT * FROM photos WHERE id = $x";
    $link = mysqli_query($conn, $queryz);

    $sql_1 = "SELECT * FROM house_info WHERE id = $x";
    $result_1 = mysqli_query($conn,$sql_1);
    $info = mysqli_fetch_array($result_1);

        $city=$info['city'];
        $type=$info['type'];
        $location=$info['location'];
        $landmark=$info['landmark'];
        $gender=$info['gender'];
        $address=$info['address'];
?>

现在的目标是让C ++跟踪对象，所以我试图创建一个随后被调用的单例。查看代码的当前状态，我试图找出这是什么，因为我已经做了多次更改，试图修复链接器错误。

总的来说，我想知道这是否真的是一个链接错误或我的类实现的问题。我倾向于后者，但仍不确定如何解决问题。

我想要的设计再次如下：

实施

：
Ada称C ++处理数据 C ++解析数据并将其存储在本地。

未实施：
Ada调用C ++来检索数据 C ++执行查找并返回数据数组。

任何帮助都会受到赞赏，因为我现在迷失在自己的代码中。谢谢！

EDIT1：

Ada代码过于强大，但我确信这一方面是正确的。至于编译器，我使用并发ANSI C / C ++编译器（PowerPC） - 5.4（005）。我不能改变编译器。前两个片段是代码的代理层。这就是Ada部分用于连接C ++代码的内容。
