最近用Qt,基类使用了模板,在派生类中提示错误: error: expected class-name before '{' token // 基类,使用了模板 template<typename T> class Base { public: Base(){} // 成员函数 void function(T &val){ }; // 派生类,必须指定基类的模板具体类型,如:<int> class Derived : public Base<int> {...
针对您遇到的“error: expected class-name before ‘{’ token”错误,这是一个在C++编程中常见的编译错误,通常指示在类定义或类继承的上下文中存在问题。以下是一些可能的原因和解决方案,分点说明: 1. 拼写错误 检查类名:确保在定义类或继承类时使用的类名完全正确,没有拼写错误。 示例: cpp class MyClass {...
今日重构之前的代码,修改了命名空间,然后一处派生的子类定义处总是总是报error: expected class-name before '{' token,网上查了查原因,出现这种情况大致有两种情况 1. 递归保护头文件; 2. 拷贝之前的代码,#ifndef XX #define XX; 我这次都不是。调了有两小时,然后不停的还原代码,最后发现是目录下面生成了一...
error: expected class-name before '{' token(转) 错误原因 1. 头文件引用的类中,结尾可能少了; ,, 例如:class Cwj{} 忘记了以;结尾哦。 2. 引用的头文件的顺序先后相互冲突:例如:Msg类中包含了#include "Socket.h"文件,但是,你却又在Socket.h中引用了#include "Msg.h".这样,就导致了先后顺序的“...
TwoOperators类定义结尾忘了分号 Common类定义的基类TwoOperators是模板类，没写模板参数 template <class T> class Common:virtual TwoOperators<T> {};
