class A { }
class B : public A {
doSomething {
C * c = new C(this);
}
}
class C
{
C(A* copy);
}
在下面的示例中,我收到以下错误:
错误:没有匹配的调用函数 到 `C::C(B* const)'
我不想在这个调用中获取 A 指针,但由于某种原因我无法通过它。可能是一些愚蠢的打字错误,但由于它是 Rhapsody 生成的,我真的觉得我无法控制为什么在编译时遇到这个问题。
尝试添加另一个头文件。它不会编译,因为需要包含很多文件,但这是执行的实际代码(更改的类名)并且底层类正在工作。

我知道这不会直接编译,但也许它可以给出一些关于为什么会出错的提示。
错误:没有匹配的调用函数 到 `F::F(A* 常量,A* 常量,A* 常量) 注:候选人是: F::F(TestContextC*, D*, IOxfActive*)
您发布的代码中的问题是:
C
。B::doSomething
正在尝试调用私有 C
构造函数。B::doSomething
没有缺少返回类型和参数列表。但是一旦你解决了这些问题并获得了这个代码:
class A { };
class C
{
public:
C(A* copy);
};
class B : public A {
void doSomething() {
C * c = new C(this);
}
};
编译干净。
使用您的代码,我收到以下错误。
:3: error: function definition does not declare parameters
:10: error: expected unqualified-id at end of input
您的错误一定来自代码中的其他地方。
确保 C 的构造函数是公共的,以便可以从 B 访问它。
