Hi.

I receicive the following Warning:
Warning: no new line at the end of file. if i Press Enter the warning disappear. However, is there anyway to disable this warning?

Here's a quick fix:

# vi <file_that_throws_newline_error>
Then type this in order:
:$ <hit enter>
A <hit enter>
<hit enter><hit escape>
:wq <hit enter>

Or, if you prefer the simple approach:

# echo "" >> <file_that_throws_newline_error>

Here's a link that might help: GCC Warning Options

Append a newline character to everyfile MIGHT help:

Code:

echo "" >> `find -iname '*.c' -type f`

Just FYI, instead of

:wq <hit enter>

(write, quit)

you can just

:x <hit enter>

(exit-with-save)

This is a valid warning. Though it looks like there's a blank line at the end of your file, that's really the \n at the end of the last line. If it isn't there, gcc has to do "something special" to use that last line because technically it isn't a line.

I have such a habit of putting that newline there that I find myself putting it in all documents!

Ahh thanks! One could use vi for years and never fully learn it's potential. Guess I need to brush up on it.

Thanks again.
