Linux环境下的程序员如果不会使用GNU make来构建和管理自己的工程，应该不能算是一个合格的专业程序员，至少不能称得上是Linux程序员。在Linux环境下使用GNU 的make工具能够比较容易的构建一个属于你自己的工程，整个工程的编译只需要一个命令就可以完成编译、连接以至于最后的执行。不过这需要我们投入一些时间去完成一个或者多个称之为Makefile文件的编写。此文件正是make正常工作的基础。-Linux environment will not be used if the programmer GNU make to build and manage their own projects, should not be regarded as a qualified professional programmers, or at least should not be called a Linux programmer. In the Linux environment using the GNU tools to make the relatively easy to build a part of your own projects, compile the entire project only need one command to be completed on the compiler to link the extent that the final implementation. However, this requires us to invest some time to complete one or more of the preparation of documents called Makefile. This document is the basis of the work make normal.
