unitest文件上未解析的外部符号(visual studio)

Question

我正在用c++和visual进行我的第一次测试，我不知道为什么，当程序中没有“未解决的外部符号”时，我遇到了一个问题。

错误97错误LNK2001:未解决的外部符号"public:静态类会话* __cdecl会话：：实例(无效)“(？\MyTest\Messages.obj@ Session @SAPAV1 1@XZ)(.)\MyTest\Messages.obj MyTest 错误98错误LNK2001:未解决的外部符号"public: char * __thiscall Config::getLanguage(void)“(?getLanguage@Config@@QAEPADXZ) (.)\MyTest\Messages.obj MyTest 错误99错误LNK2001:未解决的外部符号"class wxString StringTranslate“(?StringTranslate@@3VwxString@@A) (.)\MyTest\Messages.obj MyTest 错误100错误LNK2001:未解决的外部符号"public: void __thiscall会话：：addMSG(class std::shared_ptr)“ 错误101错误LNK2001:未解决的外部符号"public: char * __thiscall Config::getNick(void)“(?getNick@Config@@QAEPADXZ) LNK2001 MyTest 错误102错误LNK2001:未解决的外部符号"public: char * __thiscall Config::getServerAddress(void)“(?getServerAddress@Config@@QAEPADXZ) (.)MyTest\Messages.obj MyTest错误103错误LNK1120: 6个未解决的外部项

Answer 1

您正在包括一个.cpp文件

#include "lib/ClientTS.cpp"

应该是吧？

#include "lib/ClientTS.h"

Answer 2

该消息指出未解决的外部符号。

这意味着代码在语法上是正确的，但是当将所有Session和.lib文件链接在一起时，并不能找到所引用的所有外部符号(类.obj和类.lib成员函数)。

这意味着您缺少依赖关系:要么是项目中缺少源文件，要么是库文件。
