在GDB中打印子类成员 [英] Printing Sub-Class Members in GDB

问题描述

GDB中是否存在一个设置，该设置会自动从基类指针中打印(C ++)子类的所有成员，还是我总是必须在取消引用它之前将其强制转换为子类指针.

Is there a setting in GDB that automatically prints all the members of a (C++) subclass from base-class pointer or do I always have to cast it to the sub-class pointer before dereferencing it.

那是我并不总是想做的事:

That is I don't always want to do:

p *(SubClass*)baseClassInstance

推荐答案

set print object
show print object

Choose whether to print derived (actual) or declared types of objects. 

我想set print object是您所需要的，但它仅适用于多态类型.

I guess set print object is what you need but it works only for polymorphic types.
