Product(s): Microsoft C Compiler

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual C++, versions 1.0, 1.5, 1.51, 2.0, 2.1, 4.0, 4.1 
- Microsoft Visual C++, 32-bit Enterprise Edition, version 5.0 
- Microsoft Visual C++, 32-bit Professional Edition, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The following dependency scan errors and/or compiler C1083 errors are generated
when you attempt to scan dependencies or compile a header file that contains an
#include directive with leading spaces in the file name:

- Scanning dependencies on a header file included in your source file may
  generate the following error if the header file name contains leading
  spaces:

  Could not find the file FILENAME.EXT

  Here " FILENAME.EXT" is the name of the included header file.

- Attempting to compile a source file that includes a header file with leading
  spaces in the file name generates this compiler error:

  Fatal error C1083: Cannot open include file: ' FILENAME.EXT' : No such file
  or directory

  Here " FILENAME.EXT" is the name of the included header file.

RESOLUTION
==========

Delete the space(s) preceding the filename in the #include directive.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

In the 32-bit versions of windows, spaces are valid characters in the file names.
This is by design in the 32-bit versions of Visual C++.

MORE INFORMATION
================

To reproduce this error, create a text file called TEST.H and include this file
in your source file with this statement:

     #Include " TEST.H"  // Note the space between quotation mark (") and    TEST.H

Attempting to scan dependencies or compile this file, generates the listed
errors. Trailing spaces in the included filename are ignored and do not cause
errors.
