函数未定义的引用问题

PhysicsList.cc文件里面的   fPMessenger = new PhysicsListMessenger(this);报错
PhysicsList.cc:(.text+0x1d9)：对‘PhysicsListMessenger::PhysicsListMessenger(PhysicsList*)’未定义的引用

这个错误通常是由于未正确链接PhysicsListMessenger类的构造函数引起的。首先，确保PhysicsListMessenger类的构造函数在PhysicsListMessenger.cc文件中被正确实现。然后，在编译和链接代码时，确保将PhysicsListMessenger.cc文件包含在编译过程中，以便正确链接到PhysicsList.cc文件。

另外，建议检查Makefile或项目配置文件，确保PhysicsListMessenger.cc文件被正确包含在编译过程中。如果Makefile或项目配置文件正确配置了PhysicsListMessenger.cc文件，但仍然出现该错误，可能是由于其他编译选项或依赖关系导致的问题。
