生成文件：4：***遗漏分隔符。停止 [英] makefile:4: *** missing separator. Stop

问题描述

这是我的生成文件：

all:ll

ll:ll.c   
  gcc  -c  -Wall -Werror -02 c.c ll.c  -o  ll  $@  $<

clean :
  \rm -fr ll

当我尝试使清洁或使化妆，我得到这个错误：

When I try to make clean or make make, I get this error:

:makefile:4: *** missing separator.  Stop.

我怎样才能解决这个问题？

How can I fix it?

推荐答案

makefile文件有标签一个非常愚蠢的关系，每一个规则的所有操作都通过标签识别......和4号位不要让一个标签，只有一个标签，使标签...

makefile has a very stupid relation with tabs , all actions of every rule are identified by tabs ...... and No 4 spaces dont make a tab , only a tab makes a tab...

要检查我用命令猫-e -t -v makefile_name

它显示了^ I制表符和行结束与$的presence都是以确保正确依赖结束生命和标签标记为规则的行动，使他们很容易辨认的make工具... ..

it shows the presence of tabs with ^I and line endings with $ both are vital to ensure that dependencies end properly and tabs mark the action for the rules so that they are easily identifiable to the make utility.....

例如：

Kaizen ~/so_test $ cat -e -t -v  mk.t
all:ll$      ## here the $ is end of line ...                   
$
ll:ll.c   $
^Igcc  -c  -Wall -Werror -02 c.c ll.c  -o  ll  $@  $<$ 
## the ^I above means a tab was there before the action part, so this lines ok .
 $
clean :$
   \rm -fr ll$
## see here there is no ^I which means , tab is not present .... 
## in this case you need to open the file again and edit/ensure a tab 
## starts the action part

希望这有助于！
