error C4150: deletion of pointer to incomplete type 'XXXXX'; no destructor called
问题原因可能是下面情况之一:
1,成员变量所在的头文件没有引用;
2,A类和B类所属同一命名空间,且A有一个类型为B的成员变量,想通过声明class b的方式不在A的头文件中引用B的头文件,但是却把声明放在了命名空间外,例如:
class B;
namespace SP
{
class A
{
B* b1;
}
}
正确的方式是将声明放到命名空间内:
namespace SP
{
class B;
class A
{
B* b1;
}
}
