三、附加功能

一、程序(文本）——>机器语言(二进制)过程：

预处理：头文件展开、去注释、宏替换、条件编译

编译：把C变成汇编语言

汇编：把汇编变成二进制

链接：把你写的代码和C标准库中的代码合起来

二、过程

格式 gcc [选项] 要编译的文件 [选项] [目标文件]
预处理(进行宏替换)
预处理功能主要包括宏定义,文件包含,条件编译,去注释等。
预处理指令是以#号开头的代码行。
实例: gcc –E hello.c –o hello.i
选项“-E”,该选项的作用是让 gcc 在预处理结束后停止编译过程。
选项“-o”是指目标文件,“.i”文件为已经过预处理的C原始程序。
编译（生成汇编）
在这个阶段中,gcc 首先要检查代码的规范性、是否有语法错误等,以确定代码的实际要做的工作,在检查
无误后,gcc 把代码翻译成汇编语言。
用户可以使用“-S”选项来进行查看,该选项只进行编译而不进行汇编,生成汇编代码。
实例: gcc –S hello.i –o hello.s
汇编（生成机器可识别代码）
汇编阶段是把编译阶段生成的“.s”文件转成目标文件
读者在此可使用选项“-c”就可看到汇编代码已转化为“.o”的二进制目标代码了
实例: gcc –c hello.s –o hello.o
连接（生成可执行文件或库文件）
在成功编译之后,就进入了链接阶段。
实例: gcc hello.o –o hello
在这里涉及到一个重要的概念:函数库
我们的C程序中，并没有定义“printf”的函数实现,且在预编译中包含的“stdio.h”中也只有该函数的声明,而
没有定义函数的实现,那么,是在哪里实“printf”函数的呢?
最后的答案是:系统把这些函数实现都被做到名为 libc.so.6 的库文件中去了,在没有特别指定时,gcc 会到
系统默认的搜索路径“/usr/lib”下进行查找,也就是链接到 libc.so.6 库函数中去,这样就能实现函
数“printf”了,而这也就是链接的作用

函数库一般分为静态库和动态库两种。
静态库是指编译链接时,把库文件的代码全部加入到可执行文件中,因此生成的文件比较大,但在运行时也
就不再需要库文件了。其后缀名一般为“.a”
动态库与之相反,在编译链接时并没有把库文件的代码加入到可执行文件中,而是在程序执行时由运行时
链接文件加载库,这样可以节省系统的开销。动态库一般后缀名为“.so”,如前面所述的 libc.so.6 就是动态
库。gcc 在编译时默认使用动态库。完成了链接之后,gcc 就可以生成可执行文件,如下所示。 gcc
hello.o –o hello
gcc默认生成的二进制程序，是动态链接的，这点可以通过 file 命令验证

三、附加功能

E 只激活预处理,这个不生成文件,你需要把它重定向到一个输出文件里面
-S 编译到汇编语言不进行汇编和链接
-c 编译到目标代码
-o 文件输出到 文件
-static 此选项对生成的文件采用静态链接
-g 生成调试信息。GNU 调试器可利用该信息。
-shared 此选项将尽量使用动态库，所以生成文件比较小，但是需要系统由动态库.
-O0
-O1
-O2
-O3 编译器的优化选项的4个级别，-O0表示没有优化,-O1为缺省值，-O3优化级别最高
-w 不生成任何警告信息。
-Wall 生成所有警告信息
