C/C++程序编译成可执行程序步骤图文源码详解

一个C++程序被编译为目标程序的过程中经历了四个部分，分别是预处理、编译、汇编、链接。

下面将通过一个简单的C++代码分别执行预处理、编译、汇编、链接四个步骤后的结果和基本原理讲解。

注意：博主是在ubuntu20.0下编译和运行，g++版本是9.3.0

一、一个简单的C++代码

下面是一段简单的C++代码

Test1.h

#ifndef TEST1_H_
#define TEST1_H_

struct Test1
{
    Test1();
    int getVar() const;

private:
    int var;
};

#endif /* TEST1_H_ */

Test1.cpp

#include "Test1.h"

Test1::Test1()
 : var(100)
{
}

int Test1::getVar() const
{
    return var;
}

main.cpp

#include "Test1.h"

int main() {
    Test1{}.getVar();

    return 0;
}

1.1预处理

预处理主要对Test1.cpp、main.cpp和相关的头文件进行预编译成一个Test1.ii、main.ii文件。该步骤主要操作是对一些宏进行替换以及一些#include包含的头文件进行替换。下面是在ubuntu20.0下通过g++ -E命令生成预处理后的文件（注意：一般c++预处理后文件格式为*.ii，C语言是*.i）

g++ -E main.cpp -o main.ii

文件main.ii

# 1 "main.cpp"
# 1 ""
# 1 ""
# 1 "/usr/include/stdc-predef.h" 1 3 4
# 1 "" 2
# 1 "main.cpp"
# 1 "Test1.h" 1

struct Test1
{
    Test1();
    int getVar() const;

private:
    int var;
};
# 2 "main.cpp" 2

int main() {
    Test1{}.getVar();

    return 0;
}

g++ -E Test1.cpp -o Test1.ii

文件Test1.ii

# 1 "Test1.cpp"
# 1 ""
# 1 ""
# 1 "/usr/include/stdc-predef.h" 1 3 4
# 1 "" 2
# 1 "Test1.cpp"
# 1 "Test1.h" 1

struct Test1
{
    Test1();
    int getVar() const;

private:
    int var;
};
# 2 "Test1.cpp" 2

Test1::Test1()
 : var(100)
{
}

int Test1::getVar() const
{
    return var;
}

由上面的Test1.ii和main.ii两个文件可以看出，进过预处理后*.ii文件不包含任何宏定义，因为所有宏已经被展开，并且包含的文件也已经被插入到main.ii文件中。

1.1.1预处理阶段功能总结

预编译过程主要处理那些源代码文件中的以“#”开始的预编译指令。比如“#include”、“#define”等，处理规则如下：

将所有的“#define”删除，并且展开所有的宏定义
处理所有条件预编译指令，比如“#if”、“#ifdef”、“#elif”、“#else”、“#endif”
处理“#include”预编译指令，将被包含的文件插入到该预编译指令的位置。注意，这个过程是递归进行的，也就是说被包含的文件可能还包含其它文件
删除所有的注释“//”和“/* */”
添加行号和文件名标识，比如：“ # 1 "Test1.h" 1 ”，以便编译时编译器产生调试用的行号信息及用于编译时产生编译错误或警告时能够显示行号
保留所有的#pragma编译器指令，因为编译器需要使用它们

1.2编译

编译就是对预处理完后的文件进行一系列词法分析、语法分析、语义分析及优化后生成相关的汇编代码文件。

一般将预处理和汇编合并成一个步骤，linux下使用一个cc1plus来完成这两个步骤。

下面是用编译生成main.s文件命令

g++ -S main.ii -o main.s

1.2.1编译总结

由上面main.s和Test1.s两个汇编代码文件可知，编译阶段生成的是汇编代码文件。g++本质上只是后台程序的包装，根据不同参数（-E、-S、-c）要求调用预处理编译程序cc1plus、汇编器as、连接器ld。

1.3汇编

汇编器将汇编代码转化为机器可以识别和执行的指令（二进制代码），每条汇编语句几乎都对应一条机器指令。

main.o的16进制代码分析可参考这篇博客：小湿妹问沃什么是可执行程序？（全网最简洁，必看，错过后悔终生！！！）

下面是生成目标文件main.o指令

g++ -c main.s -o main.o

#或者下面命令as
# $as main.s -o main.o

main.o文件

1.3.1汇编总结

由汇编文件main.o和Test1.o文件可知，汇编器将汇编代码main.s和Test1.s生成目标文件main.o和Test1.o。目标文件main.o里面调用的类Test1::getVar()代码还没有跟实际的物理地址关联起来，暂时用0000 0000替代，故需要链接器链接后，才能跟实际成员方法地址关联。

1.3.2编译和汇编总结

1.2.1编译总结

编译一般分为6个步骤：扫描、语法分析、语义分析、源代码优化、代码生成、目标代码优化

词法分析：首先将源代码输入扫描器，运用一种类似有限状态机算法将字符分割成一系列记号(Token)，比如(var, +, 5, 10)，用lex程序可以实现词法扫描
语法分析：语法分析器将扫描器产生的记号生成语法树进行分析。语法树的非叶子节点一般是各种运算符或者括号，确定性的数字常量作为叶子节点。可以用工具yacc(Yet Another Compiler Compiler)对输入的标识生成语法树。
语义分析：语义分析对语法树的表达式有效性进行分析，分为静态语义和动态语义；静态语义包括声明和类型匹配，动态语义是在运行期进行分析，通过语义分析语法树每个节点都标识了具体类型比如int
中间语言生成：编译器会对初始的源码进行优化，比如父节点+，叶子节点8和2，即表达式8+2会会优化为一个节点10；常见的中间代码有三地址码(x = y op z)和P-代码
目标代码生成与优化：生成的目标代码*.o的成员变量和方法是没有确定的，只有在链接阶段才会确定具体的物理地址；由于不同的机器生成的目标代码不同，所以优化十分复杂

1.4链接

链接器将所有目标文件main.o、Test1.o和库通过一定逻辑组织拼接成可执行程序main。

下面是链接生成可执行程序main的命令：

g++ Test1.o main.o -o main

可执行程序main代码如下：

tjq@ubuntu:~/eclipse-workspace/Test1/src$ hexdump main -C

C语言宏函数南林yan C语言 c语言
一、什么是宏函数？通过宏定义的函数是宏函数。如下，编译器在预处理阶段会将Add(x,y)替换为((x)*(y))#defineAdd(x,y)((x)*(y))#defineAdd(x,y)((x)*(y))intmain(){inta=10;intb=20;intd=10;intc=Add(a+d,b)*2;cout<
C语言如何定义宏函数？小九格物 c语言
在C语言中，宏函数是通过预处理器定义的，它在编译之前替换代码中的宏调用。宏函数可以模拟函数的行为，但它们不是真正的函数，因为它们在编译时不会进行类型检查，也不会分配存储空间。宏函数的定义通常使用#define指令，后面跟着宏的名称和参数列表，以及宏展开后的代码。宏函数的定义方式：1.基本宏函数：这是最简单的宏函数形式，它直接定义一个表达式。#defineSQUARE(x)((x)*(x))2.带参
