makefile phony

[东大坡居士]

hi, all

i am study the makefile recently, and found a knowledge point which can not understand clearly:

in my makefile, i defined two phony target:

.PHONY: test1 test2
test1:
@echo ###########

......

test2:
@echo ===========

why make can print first phony target informatin? but when to test2, make quit encountered some error and info not print out?


Thanks!

lz怎样运行你的makefile:
make
or
make test1
or
make test2
?

......
又都是什么内容?

just: make

[mujiok2003]

try: make test2

there are several grammar mistakes, by the way:-)

和test1和test2应该没有关系,大概是.....有点问题吧.
可以贴得全一点,或者给出错信息,大家参考一下.

make test试试先,若不能打印出来,再看看@echo前面是不是TAB.

make test2试试先,若不能打印出来,再看看@echo前面是不是TAB.

每一个命令行必须以[Tab]字符开始，[Tab] 字符告诉make此行是一个命令行。
