BUG: Include Directories Cannot End with a Backslash

Article ID: 151898

Article Last Modified on 7/5/2005

APPLIES TO

This article was previously published under Q151898

SYMPTOMS

The compiler ignores some or all of the Command Line options that appear after the /I switch.

CAUSE

The compiler incorrectly parses the additional Include Directory Command Line switch if its argument ends with a backslash followed by a quotation mark. The compiler interprets the \" sequence as meaning the path contains a quotation mark.

If you set the additional Include Directories from within Developer Studio, double quotes are automatically placed around the directory name. If there is a backslash at the end of the directory name, this problem occurs.

RESOLUTION

Remove the trailing backslash character from the Include Directory.

STATUS

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

// detect the /D"_CMDLINE":)
//    CL /c test.cpp /I"test" /D"_CMDLINE"

// 
#ifdef _CMDLINE
#pragma message("Program compiled with _CMDLINE defined.")
