Makefile使用demo

Makefile 示例

使用

• .PHONY 的作用有两个

  • 一 .PHONY 后跟伪目标，直接在 Makefile 中执行 伪目标 的命令。忽略 Makefile 同级目录下的同名的文件
  • 二是提高执行makefile时的效率。

• Makefile 中执行的命令以横杠-开头，表示忽略命令执行的状态

• -j 指定CPU个数

-j [N], --jobs[=N]          Allow N jobs at once; infinite jobs with no arg.

• make -j 4 指定并行编译的任务数，可以大大缩短编译时间
