{Vim} makefile: a small problem about tabs

Previously, I simply edited the vim configuration file named. vimrc in the home directory according to the online template, as shown below:

1 "<br/> 2 set hlsearch" high light search on <br/> 3 set backspace = 2 "delete any character in the file <br/> 4 set autoindent" auto indent on <br/> 5 set r0000" <br/> 6 set showmode "show which edit mode are you in <br/> 7 set nu" set number <br/> 8 set BG = Dark "background color <br/> 9 syntax on" <br/> 10 set laststatus = 2 <br/> 11 set autoindent <br/> 12 set shiftwidth = 4" set the size of autoindent is 4 <br/> 13 set softtabstop = 4 "Enter one tab, then 4 blank show <br/> 14 "set tabstop = 4 <br/> 15 set expandtab" Vim uses the rational blks to pad the tab <br/>

The following prompt appears when the result is made:

Makefile: 4: *** missing separator. Stop.

I have always thought that my configuration file is faulty, because this has never happened before! I have searched the internet for a long time. Although I found a way to correct this problem, I still did not find a way to avoid this error by modifying the. vimrc configuration file. Mark

. The following is a simple record of the problem solving process.

 

The cause of the problem is

Here is a detailed explanation.

Yes. The reason is that make cannot parse the content contained in makefile. GNU make identifies each line of makefile based on various separators (:, =, [Tab] characters) when reading makefile. The above error means that make cannot find a valid separator. The possible cause of this error message (maybe the editor, most of which is the MS-Windows Editor) is that four (or eight) commands are used before makefile commands) A space replaces the [Tab] character. Because all the command lines in makefile should start with the [Tab] character.

 

When I write the MAKEFILE file, the [Tab] is already used. To verify it, run the OD command to check my MAKEFILE file as follows:

Lianbequat @ Ubuntu:/home/advances/pthread/condition_var $ OD-T c makefile <br/> 0000000 C = g C/n C o n d 1: c o <br/> 0000020 n d 1. c/N $ (C) <br/> 0000040 $ ^-o $ @/n <br/> 0000051 <br/>

The [Tab] tab I typed has been automatically replaced with four spaces by the editor! Here

Find the answer to this problem, that is

In Vim editing mode, press Ctrl + V + I to write a tab key. Run the command again in make. Check my MAKEFILE file again in the ASCII code format and find that the four spaces have been replaced by "/T", as shown below:

Lianbequat @ Ubuntu:/home/advances/pthread/condition_var $ OD-T c makefile <br/> 0000000 C = g C/n C o n d 1: c o <br/> 0000020 n d 1. c/N/T $ (C) $ ^ <br/> 0000040-p t h r e a d-o $ @/n <br/> 0000057 <br/>

 

Note: The problem is not completely solved. It is impossible for me to use the combination key "Ctrl + V + I" to type each [Tab] key every time I write makefile ?! Therefore, you have to continue looking for problems. If I have not learned enough, I should first record it as "half-cut.

Find the cause, just comment out the configuration command in the last line of. vimrc! You can see it at a glance.
