makefile has a very stupid relation with tabs, all actions of every rule are identified by tabs. And no, 4 spaces don't make a tab, only a tab makes a tab.

makefile 与制表符的关系非常愚蠢，每个规则的所有操作都由制表符标识。不，4 个空格不能构成制表符，只有制表符才能构成制表符。

to check I use the command cat -e -t -v makefile_name

检查我使用命令 cat -e -t -v makefile_name

It shows the presence of tabs with ^Iand 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.

它显示了选项卡的存在^I和行结尾$对确保依赖关系正确结束至关重要，选项卡标记规则的操作，以便 make 实用程序可以轻松识别它们。

Example:

例子：

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 line is 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

On VS Code, just click the "Space: 4" on the downright corner and change it to tab when editing your Makefile.

在 VS Code 上，只需单击右下角的“Space: 4”并在编辑 Makefile 时将其更改为选项卡。

You should always write command after a Taband not white space.

你应该总是在 aTab而不是空格之后写命令。

This applies to gccline (line #4) in your case. You need to insert tab before gcc.

gcc在您的情况下，这适用于行（第 4 行）。您需要在gcc.

Also replace \rm -fr llwith rm -fr ll. Insert tabs before this command too.

也替换\rm -fr ll为rm -fr ll. 在此命令之前也插入制表符。

The solution for PyCharmwould be to install a Makefile supportplugin:

解决方案PyCharm是安装一个Makefile support插件：

1. Open Preferences(cmd + ,)
2. Go to Plugins-> Marketplace
3. Search for Makefile support, install and restart the IDE.

1. 打开Preferences( cmd + ,)
2. 去Plugins->Marketplace
3. 搜索Makefile support、安装并重新启动 IDE。

This should fix the problem and provide a syntax for a makefile.

这应该可以解决问题并为生成文件提供语法。

Its pretty old question but still I would like say about one more option using vi/vimeditor to visualize the tabs. If you have vi/viminstalled then open a Makefile(e.g. vim Makefile) and enter :set list. This will show number of tabs inserted as below,

这是一个很老的问题，但我仍然想说一个使用vi/vim编辑器可视化选项卡的选项。如果您已vi/vim安装，则打开Makefile（例如vim Makefile）并输入:set list. 这将显示插入的选项卡数量，如下所示，

 %-linux: force$
^I@if [ "$(GCC_VERSION)" = "2.96" ] ; then $
^I^Iecho ===== Generating build tree for legacy $@ architecture =====; $
^I^I$(CONFIGURE) $(CWD) $@ legacy; $
^Ielse $
^I^Iecho ===== Generating build tree for $@ architecture =====; $
^I^I$(CONFIGURE) $(CWD) $@; $
^Ifi$
^Icd build-$@;make$

Using .editorconfigto fix the tabs automagically:

使用.editorconfig，自动将修复标签：

root = true

[*]
charset = utf-8
end_of_line = lf
insert_final_newline = true
indent_style = space
indent_size = 4

[Makefile]
indent_style = tab

The key point was "HARD TAB" 1. Check whether you used TAB instead of whitespace 2. Check your .vimrc for "set tabstop=X"

关键点是“HARD TAB” 1. 检查您是否使用 TAB 而不是空格 2. 检查您的 .vimrc 中的“set tabstop=X”
