Asked 'Make' gurus today about this and here's what Paul D. Smith confirmed: "RECIPEPREFIX must be set to exactly one unique character. There's no way to set it to be "four spaces". Also note that this feature is only available in the latest version of GNU make and many systems do not include that version yet, so if you use this feature your makefiles will not be portable to older systems (you might not care about that).

Thank you. With your work around I do not need to edit my vimrc file everytime i need to write a Makefile.

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

I have my vimrc file setup to use different tabs/spacing depending on the filetype.  8-width tab in C, 4-space indent in Python, etc...

Here's a snippet from my vimrc:

"-------- C ------------------------- function! LANG_C()    setlocal noexpandtab    setlocal shiftwidth=8    setlocal tabstop=8    setlocal softtabstop=8    setlocal formatoptions=tcroq endfunction autocmd FileType c call LANG_C()

"------- Python ---------------- function! LANG_PYTHON()    setlocal shiftwidth=4    setlocal tabstop=4    setlocal softtabstop=4    setlocal expandtab    "--- python indent keywords --------    setlocal cinwords=if,elif,else,for,while,try,except,finally,def,class,with endfunction autocmd FileType python call LANG_PYTHON()

"------- Makefile -------------- function! LANG_MAKEFILE()    setlocal noexpandtab     " makefiles only work with tab-indents    setlocal shiftwidth=8    setlocal tabstop=8    setlocal softtabstop=8 endfunction autocmd FileType make call LANG_MAKEFILE()

There may be other/better ways to do this, but it works well for me.
