最近发现一个很好用的Makefile模板，简单修改后几乎可以适配所有常用场景。

代码目录结构：

├── Makefile
├── bin
│   └── crudc
├── debug
├── obj
│   ├── crudc.o
│   └── test.o
└── src
    ├── crudc.c
    ├── list.h
    └── test.c

使用步骤：

  • 按以上目录结构组织代码
  • Makefile中，配置好这几个变量：CC, CCFLAGS, DBGFLAGS, CCOBJFLAGS, TARGET_NAME
  • make 或 make debug
