!IF !EXISTS(foo.txt) !ERROR Unable to locate foo. !ELSE !MESSAGE I Found foo! !ENDIF 8投票 为了补充 Jack Kelly 的建议,您可以在 CMD.EXE shell 中测试是否存在。 NMake 还包括创建临时 .cmd 文件并执行它的功能。 这是(n)makefile 语法的示例,我将其用于“检查语法”目标。它通过执行编译来...
The above command makes the shell run the script named configure which exists in the current directory. The configure script basically consists of many lines which are used to check some details about the machine on which the software is going to be installed. This script checks for lots of d...

pgrep是一个用于查找进程的命令,它可以根据进程的名称或其他属性来查找进程的PID(进程ID)。在makefile中使用pgrep返回true,但在shell中不返回true的原因可能是环境变量的差异。 在makefile中,通常会定义一些特定的环境变量,以便在构建过程中使用。这些环境变量可能会影响pgrep命令的执行结果。例如,可能会设置一个...

The make tool will stop running a rule (and will propogate back to prerequisites) if a command returns a nonzero exit status. DELETE_ON_ERRORwill delete the target of a rule if the rule fails in this manner. This will happen for all targets, not just the one it is before like PHONY...
