嵌入式项目Makefile设计的一般方法
http://blog.csdn.net/embeddedsoft/article/details/1583571转自
本文以视频会议项目为背景，讨论如何使用WindRiver Tornado2.2的GNU工具链中的make工具编译各个模块的源代码，为嵌入式项目创建Makefile提供一般的设计方法。
具体方法如下：
１．先为所有模块，如下图中的code/source/appl目录下dp_new、gc、mc等编写一个全局的Makefile,取名为Makefile.global,放在code/include中。这个全局ＭＡＫＥＦＩＬＥ用于指明工具链、各个子模块的相对路径、obj文件存放的位置，要引用的头文件和库文件目录等。
２．为各个模块如dp_new,gc,mc等编写子Makefile。在这些子Makefile使用include引用Makefile.global并指明要编译的源文件和编译规则已经最终要生成的目标，这里以gc模块为例，来说明如何书写便宜规则！
