浅谈linux 中的目标文件 即.o后缀名的文件
实际上 目标文件从结构上讲,已经非常接近可执行文件,只是没有经过链接的过程,所以其中有些符号或者地址还没有被调整。
实际上上在linux下 都是可以称之为ELF文件。
看一下这个图,a.out 就是我们的hello.c的执行文件。hello.o 就是目标文件 所以实际上他们2 几乎是一样的。
一般目标文件有很多属性,比如符号表啊,字符串之类的,然后目标文件 把这些属性 按照 segment的形式存储,也叫段。就是大家经常遇到的段错误
里的那个段。
一般来说程序代码被编译以后 主要分为程序指令和程序数据。有人会问为什要分开放。不能一起放。因为 程序指令是不可写的,而程序数据 是可读可写的。在os中,数据和指令是
分别映射到2个不同的区域里面的。所以分开放置,可以防止恶意程序修改我们的程序。
此外 当一个程序 同时运行好几份拷贝时,举个栗子 我们同时开5个qq。这个时候 我们qq的指令区 实际上在os中 只有一个。只不过 不同的qq 有不一样的数据区。这样很节省内存。
另外现在的cpu缓存都被设计成了指令缓存和数据缓存。所以 数据区和指令区分开 有利于提高cpu的缓存命中率、
然后我们实际来看一看 .o文件的构成把。
输入命令: objdump -h hello.o
size就是段的长度 name是段的名称(大家可以自己百度这些段名称代表什么)
然后我们可以看一下 每个段的实际内容
输入命令 objdump -s -d
其实结构还是很清晰的,大家可以自己写个稍微复杂的程序然后分析它的目标文件内容。
我们还可以查看下linux下的elf文件 具体信息
输入命令 readelf -h hello.o
实际上呢 这个elf文件头结构 是定义在usr/include/elf.h里面的。我们可以看看这个文件的大概内容

实际上,在链接中,目标文件的相互拼接实际上就是目标文件之间的地址引用。即对函数和变量的地址引用。
无论是可执行文件,目标文件,或者库,实际上都是一样基于段的文件或者是这种文件的集合,程序的源代码经过编译以后,按照代码和数据分别存放到
相应的段中,当然编译器还会将一些辅助的信息,比如符号,重定位信息也按照表的方式存放到目标文件中,并且一般情况下,一个表往往就是一个段。
有了这些目标文件,静态链接 就会将他们组合起来,形成一个可用的程序或者说更大的模块。
