B对A的继承是private的,于是后续继承B的子类都会把A看作是B的private,无法访问。 至于解决办法,倒也很简单: struct A { static void Run(){ } }; struct B : private A { }; struct C : public B { void Run() { // A::Run(); ::A::Run(); } }; int main() { C c; c.Run(); ...

Second, when a derived class inherits from a base class, the access specifiers may change depending on the method of inheritance. There are three different ways for classes to inherit from other classes: public, private, and protected.
其实private/public 解决的是指示问题,本质上可以使用public 来解决, 可以减少坑。 下面是target_link_libraries中的解释,不想看英文的,直接拉到最后。 Link Inheritance Similarly, for anytarget, in the linking stage, we would need to decide, given theitemto be linked, whether we have to put theitem...
