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make -j 4 指定并行编译的任务数，可以大大缩短编译时间，-j 指定CPU个数
-j [N], --jobs[=N] Allow N jobs at once; infinite jobs with no arg.
shell 函数 参数是操作系统的 shell 命令，功能和使用 (`) 相同
- 示例
ipaddress := $(shell ip a)
