Need help: How to set .RECIPEP RE​FIX variable to white spaces

[Kumar Mehta]

Hi,

How to set .RECIPEPREFIX variable to whitespace(say 4 whitespces) , so that
make uses this particular set of characters to identify the recipe for a
particular target.
In my $HOME/.vimrc file, for code indentation purpose, I've put the
following entries to replace tabs with 4 whitespaces:

<<<snip from my $HOME/.vimrc file>>>
"replace tabs with spaces
set expandtab
set shiftwidth=4
set tabstop=4
<<<snip from my $HOME/.vimrc file>>>


but the above will cause problem in case you write your own makefile for a
kernel module,
because now the tab stroke will be replaced by 4 whitespaces which 'make'
will not understand. Quoting from 'make' manual,
"Please note: you need to put a tab character at the beginning of every
recipe line!"

Seems .RECIPEPREFIX will come for resuce, but as of now I don't know how to
use it to fix my problem.

Regards,
Amit
