unitest文件上未解析的外部符号（Visual Studio）

Question

我正在使用 c++ 和 Visual Studio 进行我的第一次测试，但我不知道为什么，当它没有在程序中发生时，我遇到了“未解析的外部符号”的问题。

错误 97 错误 LNK2001: 无法解析的外部符号“public: static 类 Session * __cdecl Session::Instance(void)" (?Instance@Session@@SAPAV1@XZ) (...)\MyTest\Messages.obj MyTest

错误 98 错误 LNK2001: 无法解析的外部符号 "public: char * __thiscall Config::getLanguage(void)" (?getLanguage@Config@@QAEPADXZ) (...)\MyTest\Messages.obj MyTest

错误 99 错误 LNK2001：无法解析的外部符号“类 wxString 字符串翻译” (?StringTranslate@@3VwxString@@A) (...)\MyTest\Messages.obj MyTest

错误 100 错误 LNK2001: 无法解析的外部符号 "public: void __thiscall Session::addMSG(class std::shared_ptr)" (?addMSG@Session@@QAEXV?$shared_ptr@VMessage@@@std@@@Z)(...)\speech-translation-tools\MyTest\Messages .obj 我的测试

Answer 1

您正在包含一个 .cpp 文件

#include "lib/ClientTS.cpp"

应该吗？

#include "lib/ClientTS.h"

Answer 2

消息指出未解析的外部符号。

这意味着您的代码在语法上是正确的，但在将所有 .obj 和 .lib 文件链接在一起时，并没有找到您引用的所有外部符号（Session 类和Config 类成员函数）。

这意味着您缺少依赖项：项目中缺少源文件，或者“更可能”是库文件。
