类gdt_manager有虚函数但非虚析构函数。

如何修复它？

what does this mean?
That the class gdt_manager has virtual functions but non-virtual destructor.
how to fix it?

使析构函数虚拟化。

By making its destructor virtual.

警告不等于错误。你应该让析构函数虚拟。

但不是必须

warnings are not equal to error. you should make destructor virtual.
but not must
