'æpile和built分别是什么意思
一个C/C++程序的生成要经历以下步骤:
1.编写文本代码,生成C或cpp文件,源码源码这时候它还是无错完整文本的;
2.编译,就是源码源码dpdk vpp源码分析compile,由C编译程序对你写的无错完整代码进行词法和句法分析,发现并报告错误,源码源码承德安卓源码有错时编译不能通过。无错完整如若无错,源码源码则生成中间代码,无错完整扩展名为obj,源码源码此时它便是无错完整二进制的了;
3.连接,在汇编里称link,源码源码在C里叫生成,无错完整祥云卡网源码即build,源码源码它的无错完整作用是生成可执行的exe文件。由于一个程序的源码从哪里来源码可由多个文件组成。这些文件在第二步中分别编译,生成各自的目标文件(*.obj),这一步的源码模板网资源作用便是将这些obj文件,以及程序中需要的其它库文件(dll除开),统一到一个文件中来,形成单个的exe文件。
此exe文件便可以在操作系统下直接运行了。 上述第二步做完中间代码生成的工作后还有个代码优化,这里就不详讲了。
compile、build分别对应编译和连接这两个过程。
