错误 LNK2019：无法解析的外部符号“toString(int)”

发布于 2024-12-11 08:38:58 字数 14535 浏览 0 评论 0原文

环境：Windows XP。 Visual Studios 2010。语言 - C++。

我遇到了以下链接错误&已经没有办法解决这个问题了。我有一个项目（CnD Device），它链接到我的团队控制的 2 个项目（Messages 和 Carbon）。我尝试在 3 个项目之间搜索项目属性，

enter tcp_driver.obj : error LNK2019: unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl toString(int)" (?toString@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@H@Z) referenced in function "protected: bool __thiscall Tcp_Driver::readMessage(void)" (?readMessage@Tcp_Driver@@IAE_NXZ)

我相信这个问题是因为我没有链接到标准 C++ 库中的字符串。我一遍又一遍地扫描我的财产清单。以下是我认为对于此问题至关重要的一些属性。

CnD 设备属性信息：

  1. 配置类型 动态库.dll
  2. 使用 MFC 在共享 DLL 中使用 MFC
  3. 使用 ALT 不使用 ALT
  4. 字符集 使用多字节字符集
  5. 运行时库 多线程 DLL (/MD)
  6. 其他依赖项 msvcprtd.lib、Carbon.lib、 BUFFER_API.lib、BUFFER_FRAMEWORK.lib、Messages.lib
  7. 忽略所有默认库 无

消息属性信息：

  1. 配置类型 静态库 (.lib)
  2. MFC 的使用 在共享 DLL 中使用 MFC
  3. 使用 ALT 不使用 ALT
  4. 字符集 使用 Unicode 字符集
  5. 运行时库多线程 DLL (/MD)
  6. 其他依赖项
  7. 链接库依赖项 无

Carbon 属性信息：

  1. 配置类型 静态库 (.lib)
  2. 使用 MFC 在共享 DLL 中使用 MFC
  3. 使用 ALT 不使用 ALT
  4. 字符集 使用 Unicode 字符集
  5. 运行时库线程DLL (/MD)
  6. 链接库依赖项 否

我的 CnD 链接输出是：

原文

Environment: Windows XP. Visual Studios 2010. Language - C++.

I have run into the following link error & have run out of ideas how to fix this problem. I have a project (CnD Device) which links to 2 projects (Messages & Carbon) controlled by my group. I have tried to search for project properties between the 3 projects

enter tcp_driver.obj : error LNK2019: unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl toString(int)" (?toString@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@H@Z) referenced in function "protected: bool __thiscall Tcp_Driver::readMessage(void)" (?readMessage@Tcp_Driver@@IAE_NXZ)

I believe this problem is because I am not linking to the string which is in Standard C++ Library. I have scanned my properties list over and over again. Below is some of the properties I believe are critical for this problem.

CnD Device property information:

  1. Configuration Type Dynamic Library .dll
  2. Use of MFC Use MFC in a Shared DLL
  3. Use of ALT Not Using ALT
  4. Character Set Use Multi-Byte Character Set
  5. Runtime Library Multi-threaded DLL (/MD)
  6. Additional Dependencies msvcprtd.lib, Carbon.lib, BUFFER_API.lib, BUFFER_FRAMEWORK.lib, Messages.lib
  7. Ignore All Default Libraries No

Messages Properties Information:

  1. Configuration Type Static Library (.lib)
  2. Use of MFC Use MFC in a Shared DLL
  3. Use of ALT Not Using ALT
  4. Character Set Use Unicode Character Set
  5. Runtime Library Multi-threaded DLL (/MD)
  6. Additional Dependencies
  7. Link Library Dependencies No

Carbon Properties Information:

  1. Configuration Type Static Library (.lib)
  2. Use of MFC Use MFC in a Shared DLL
  3. Use of ALT Not Using ALT
  4. Character Set Use Unicode Character Set
  5. Runtime Library Multi-threaded DLL (/MD)
  6. Link Library Dependencies No

我发现了我的问题。我会删除这个；然而，我发现这个链接错误很常见，但除了项目属性更改之外，从来没有好的通用解决方案。

我的问题的根源：
Carbon 和 Messages 将 Int32 定义为 long。

CnD 将 Int32 定义为 int。

导致错误的未解析的外部符号是

extern std::string toString(Int32 v);

因此 CnD 期望的函数与 Carbon 和 Messages 定义的函数不同。

I found my problem. I would delete this; however, I found this link error is common but never have good general solutions - besides project property changes.

The source of my problem:
Carbon and Messages defined Int32 as a long.

CnD defined Int32 as an int.

The unresolved external symbol causing the error was

extern std::string toString(Int32 v);

Thus CnD was expecting a different function than what Carbon and Messages defined.
