Compiler Warning (level 1) C4335

  • Article

Mac file format detected: please convert the source file to either DOS or UNIX format

The line termination character of the first line of a source file is the old Macintosh style ('\r') as opposed to UNIX ('\n') or DOS ('\r\n').

This warning is only issued once per translation unit. Therefore, if there are multiple #include directives that specify files in Macintosh format, C4335 is emitted once.

One way to generate files in Macintosh format is by using the Advanced Save Options (on the File menu) in Visual Studio.

Example

The following sample generates C4335.

// C4335 expected
#include "c4335.h"   // assume both include files are in Macintosh format
#include "c4335_2.h"
