c++ - 类未定义 C++

Question

在测试中，我试图创建对象 partTimeEmployee，但出现 undefined reference 错误，我不明白为什么？我不明白这个错误，因为我传递了正确类型的数据。我的 .cpp 和 .h 不包括在内吗？

test.cpp: (.text+0xb7): 未定义对“partTimeEmployee(std::basic_string, std::allocator >)”的引用

改变

class partTimeEmployee : public partTimeEmployee

到

class partTimeEmployee : public Employee
