我的c ++代码有问题。
这是我的代码。
2个cpp文件（main.cpp，function.cpp） 2个头文件（1代表程序描述，1代表库和函数原型）
这四个文件位于同一个文件夹中，名称简单。在该文件夹中，还有一个项目文件。
我从Codeblock 12.11版本创建了一个项目，删除了项目中的默认main.cpp。
从代码块顶部的项目栏中，我在上面添加了两个cpp文件，但没有添加两个头文件。这是我教授的指示。
我在main.cpp中包含了两个头文件，并在function.cpp中包含一个头文件（包含库）。
当我运行它时，它构建并运行良好。然而，当我将我的项目发送给我的教授时，他无法运行该项目。他说代码立即存在，没有任何反应。
在我的Windows代码块中，我编写项目的IDE编译器程序，我找不到任何错误。 但是，当我使用codeblock从我的mac（我有2台计算机）尝试相同的项目时，没有错误，但是会出现这样的警告。
警告：ld：警告：忽略文件obj / Debug / function.o，文件是为不支持的文件格式构建的（0x4c 0x 1 0x c 0x 0 0x 0 0x 0 0x 0 0x 0 0x .... 0 0x 0 ）这不是被链接的体系结构（x86_64）：obj / Debug / function.oignoring file obj ....
===构建失败：0错误。 1警告（0分钟，0发送）===
我不知道在哪里修理。
这是我的main.cpp。

描述文件的名称是Project_Description.h 它不会添加到项目中，而是与项目和两个cpp文件位于同一文件夹中。 它从
开始/ *
并以
结束* /
在评论的旁边有程序的描述。 并且没有任何内容在评论之外。
还有另一个头文件，里面有原型库。
文件名是Project_Header.h
看起来像这样。
#include <iostream>
#include<cstring>
using namespace std;
int quizs (int score);
//in this function, student gonna start the quizs, and this function will call quation1-13
//functions to test student
void question1(double *answer, double *stanswer);
void question2(double *answer, double *stanswer);
void question3(double *answer, double *stanswer);
void question4(double *answer, double *stanswer);
void question5(double *answer, double *stanswer);
void question6(double *answer, double *stanswer);
void question7(double *answer, double *stanswer);
void question8(double *answer, double *stanswer);
void question9(double *answer, double *stanswer);

void question11(double *answer, double *stanswer);
void question12(double *answer, double *stanswer);
void question13(double *answer, double *stanswer);
这是结束。
有人可以帮我找到错误并修复它吗？
答案 0 :(得分：0)
错误意味着您正在尝试链接在Mac上的Windows计算机上编译的目标文件。由于不同的硬件架构，这是不可能的。尝试删除项目中的.o文件，并从头开始重新编译。
一般来说，你的文件存在第二个问题，CodeBlocks似乎以某种方式修复但是如果你从终端编译它会导致问题：function.cpp永远不会编译，这会导致链接错误，因为链接器不会找到您在此文件中实现的功能的代码。
一个修复是在main.cpp文件中包含function.cpp，第二个用-c选项分别编译这两个文件（g ++ -c main.cpp和g ++ -c functions.cpp）并链接它们之后（g ++ main.o functions.o -o main）。
希望有所帮助。
