“environment” 如果<variable>是一个环境变量,并且当Makefile被执行时,“-e”参数没有被打开。 “file” 如果<variable>这个变量被定义在Makefile中。 “command line” 如果<variable>这个变量是被命令行定义的。 “override” 如果<variable>是被override指示符重新定义的。 “automatic” 如果<variable>是一个...
makefile 中的$(1) $(2)用来表示call函数传过去的实参, call函数原型: $(call variable,param,param,…) call函数相当于c语言中函数调用,variable(函数名),param(实参1),param(实参2)... 由于调用的variable(函数名)函数的书写规范是不能带形参的,就用$(1),$(2)..表示第一个第二个形参 如: define ...
5.3.2 Choosing the Shell The program used as the shell is taken from the variable SHELL. If this variable is not set in your makefile, the program /bin/sh is used as the shell. The argument(s) passed to the shell are taken from the variable .SHELLFLAGS. The default value of .SHELL...
targets: prerequisites command command command 其中,targets是我们要执行指令的名字,prerequisites是我们要执行指令的前置条件,command是我们要执行的指令。 需要注意的是,command前面需要有tab键(多个tab也可以),但不能使用空格。 hello: echo "Hello, World" 执行make,结果如下: 可以看到,在执行make后,它会先将我...
edit : main.o command.o...cc-o edit main.o command.o... 第一行说明文件的依赖关系,edit 是由 main.o command.o... 这几个文件链接而成的,依赖于他们。如果其中某个或多个 xx.o... 文件日期比 edit 新或者 edit 不存在,那么依赖关系就发生了。

NMAKE searches for filename first in the specified or current directory, then recursively through directories of any parent makefiles, then, if filename is enclosed by angle brackets (< >), in directories specified by the INCLUDE macro, which is initially set to the INCLUDE environment variable...
