在C语言中,遇到“has incomplete type”错误通常意味着你试图使用一个尚未完整定义的类型。 错误原因 不完整类型(Incomplete Type)是指在当前作用域中仅声明了类型名,但尚未给出其完整定义的类型。这通常发生在以下几种情况: 结构体或联合体仅声明未定义:在头文件中只声明了结构体或联合体的标签,但没有包含其完整...
cpp报错:C-struct error-Field has incomplete type 程序定义如下代码: structNode { Nodeson; }; 1. 2. 3. 4. The error means that you try and add a member to the struct of a type that isn’t fully defined yet, so the compiler cannot know its size in order to determine...
一是,假设第一个链表结点是头结点(不包含实际数据,方便后续操作),那么这个结点的一个成员变量prev就不好赋空,因为NULL是赋给指针的,int a=NULL编译器会警告. 二是根本原因,The error means that you try and add a member to thestructof a type that isn't fully defined yet, so the compiler cannot k...
has incomplete type and cannot be defined 在头文件中添加该类型所在的文件 eg:aggregate 'std::stringstream oss' has incomplete type and cannot be ;在文件中添加 include <sstream> 来解决。
Linuc C 一直编译报错 struct timespec has initializer but incomplete type,GCC是linux环境下,编译C程序的常用工具。下面整理和总结一下常用的编译和执行指令。给需要帮助的初学Linux下C编程的同学看一下,希望会有帮助。1.单个源程序。假设源程序名为:hello.c编译的指
include#include.QPixmappm;QVectorvPixmap;这种写法编译是没错的。但是QVectorvPixmap;会报错。
因为这是参数声明，它将自动调整为指针。可以有指向不完整类型的指针;struct student *arr是允许的。但是...
你把两个结构体的位置换一下
To create an array of incomplete types, declare an array type without specifying its repetition count. For instance: charbook_name[];/* book_name has incomplete type */ Declare the same name later in the same scope with its repetition count set to finish an incomplete array type. ...
An array type is completed by specifying the array size in a following declaration in the same scope that denotes the same object. When an array without a size is declared and initialized in the same declaration, the array has an incomplete type only between the end of its declarator and ...
