什么是makefile？或许很多Winodws的程序员都不知道这个东西，因为那些Windows的IDE

都为你做了这个工作，但我觉得要作一个好的和professional的程序员，makefile还是要懂。

这就好像现在有这么多的HTML的编辑器，但如果你想成为一个专业人士，你还是要了解HTML

的标识的含义。特别在Unix下的软件编译，你就不能不自己写makefile了，会不会写makefile，

从一个侧面说明了一个人是否具备完成大型工程的能力。-What is a makefile? Many programmers may not know Winodws this thing, because those are Windows-IDE to do this work for you, but I think to make a good and professional programmer, makefile, or to understand. It' s like there are so many HTML editors, but if you want to be a professional, you still have to understand the meaning of the identity of HTML. Particularly in the software compilation under Unix, you have to write your own makefile, and will not write makefile, from one side shows whether a person has the ability to complete major projects.
