Hi,

I'm having a weird problem when using Visual Studio. I'm creating a
small library with different utility classes. Thing is that everything
compiles ok, but when I create a string.h / string.cpp files, I get
the following errors:

***
\microsoft platform sdk for windows server 2003 r2\include
\guiddef.h(161) : error C3861: 'memcmp': identifier not found
\microsoft platform sdk for windows server 2003 r2\include
\stralign.h(101) : error C3861: 'wcscpy': identifier not found
***

Also, if I used std::string internally in my string class (to make my
class a wrapper over the std's string), then I'd get far more errors
(please note that 100+ errors are displayed)

The really strange thing, at least to me, is that so far none of the
other files in my library relies on string.h, so it seems that its
sole existence confuses MSVC somehow. One solution I thought was
avoiding the system include directory, but the problem is that some of
the classes need access to win32 api, so I need it.

Simple solution so far: just renaming string.h to stringxxx.h and
everything works ok. But of course, I'd like to use string.h for
clarity sake. Is there any workaround for this?

Thanks in advance.

My guess is that you'd fix your problem by just using a name that wasn't
already taken as one of the standard names. Did you include string.h in
your string.cpp file and include it in the project. That alone would be
enough to attempt to cause the problem. Maybe you could call yours
MyString.h or something like that.

Possibly the standard C library [string.h] is included instead of your [string.h].

To include the C library [string.h]:

#include <string.h>

To include your own, in the directory of the file containing this directive,

#include "string.h"

To avoid problems, choose some other name.


Cheers, & hth.,

Hi there,

Yes, of course I do #include "String.h" in the .cpp file, and also
both files are included in the project.

Renaming fixes this, but alas, given that this is intended to be a
library providing some api to replace the natives, it would have been
nice to call it "String.h".. Also, when compiling with other
toolchains (gcc), this doesn't cause any problem..

Thanks anyway.

I do exactly that, I use "" for my own headers, and <> for system's.
It seems the problem is in the include directory search order..

Yes, I think I'll end up doing that.. it surprises me that noone faced
this issue before, as it's quite common to have a file named string.h
in your own project. And I've been looking other libs and they indeed
use string.h, but have makefiles so probably they avoid the issue some
other way.

Thanks.
