当你遇到“undefined reference to add(int, int)'”这个错误时,通常意味着编译器在链接阶段找不到add(int, int)`函数的定义。这里有几个可能的原因和相应的解决方法: 确认add(int, int)函数的声明是否存在: 确保在你的代码中有一个函数声明,例如: c int add(int a, int b); 这个声明通常放在头文件...

undefined reference to `std::cout'等错误 (1)gcc和g++都是GNU(组织)的一个编译器。 (2)后缀名为.c的程序和.cpp的程序g++都会当成是c++的源程序来处理。而gcc不然,gcc会把.c的程序处理成c程序。 (3)对于.cpp的程序,编译可以用gcc/g++,而链接可以用g++或者gcc -lstdc++。
