可以简单的认为是直接替换,更具体的是inline function expand,inline展开与include头文件的替换是不同的),当调用fun_A的位置都展开之后,相当于fun_A不存在了,也就不会引起multiple definition。 static 属性 限制作用域 (非class static func),B.o中的fun_A对应B.cpp中的fun
问题:某个头文件中声明并定义了一个函数,然后在多个源码文件中调用该函数,编译链接时出现了该函数 multiple definition 问题,在头文件中添加了 #ifndef 头也不行,经过尝试发现如果将该函数的声明和定义分开到. h 和. cpp 文件之后问题消失,为什么不能将函数直接定义在. h 文件中呢? 针对该问题,抽象出如下几个...
I create a program that after the compiling gives to me an error from linker, apparently there are multiple definition of lots function i use. The structure of my program is like this one: class 1 { do things } 12 #include "class 1" class 2 { do things } 12 #include "class 2" ...
结果链接时出现错误: multiple definition of ‘STR_TEST’ 虽然改为#define肯定行,但是尽量应该用const量取代宏定义。 这里有个概念性错误。 const 变量默认是 static 的, 但带有 const 的不一定是 const 变量. 此处STR_TEST 并不是常量,而是指向常量字符串的变量。 改为 const char * const STR_TEST = "He...

multiple definition of mainc语言multiple definition of mainc语言 在C语言中,main函数是程序的入口点,也就是说,程序从这里开始运行。在一个C程序中,只能有一个main函数。如果你尝试在多个位置定义main函数,编译器会报错,说你有多个定义。 例如,以下代码就会导致“multiple definition of main”的错误: c // ...
