LNK2001&的错误修复方法LNK2019 [英] How to fix error LNK2001 & LNK2019

问题描述

ProjectAAA.obj:错误LNK2001:无法解析的外部符号"public:__thiscall X :: ClassEvent :: ClassEvent(unsigned int)"(?? 0ClassEvent @ X @@ QAE @ I @ Z)

ProjectAAA.obj : error LNK2001: unresolved external symbol "public: __thiscall X::ClassEvent::ClassEvent(unsigned int)" (??0ClassEvent@X@@QAE@I@Z)

boost::shared_ptr<ClassEvent> bcfEvent(new ClassEvent((unsigned int) 10));

我已经定义了ClassEvent::ClassEvent(unsigned int)，并且不知道如何解决此LINK错误.

I have defined ClassEvent::ClassEvent(unsigned int) and have no idea how to fix this LINK errors.

任何建议都值得赞赏.

谢谢

推荐答案

经过多次测试，我找到了解决方案.

After multiple testing, I found the solution.

团队中的某人从项目中排除了ClassEvent.CPP ！！！

Someone in the team excludes the ClassEvent.CPP from the project!!!
