多變量定義不Makefile中

Question

工作，我試圖用一個multiline variable definition in my Makefile，它似乎並沒有爲我工作：

$ cat Makefile 
define foo = 
I'm a little teapot 
short and stout 
here is my handle 
here is my spout 
endef 

all: 
    echo "$(foo)" 
$ make all 
echo "" 

$ make --version

我在做什麼錯？

Answer 1

試試這個：

define foo 
I'm a little teapot 
short and stout 
here is my handle 
here is my spout 
endef 

$(info $(foo)) 


all: 
    echo the shell dislikes multiline variables 

的「=」似乎並沒有在define報表工作在3.81，如果你回聲一個多變量，shell會後的第一個解釋線如命令。
