Release mode problem

Hi to all,

If I am compiling through debug mode my project works fine but I am compiling through release mode it gives following warning and program crashes at runtime.

LINK : warning LNK4089: all references to "ADVAPI32.dll" discarded by /OPT:REF
LINK : warning LNK4089: all references to "MSVCP60.dll" discarded by /OPT:REF

The above warning is given by compiler if am included one .cpp and .h file in my project.In that file I have included
#include <string>
#include "stdafx.h"

these two files and used STL string class.

I hope that I got answer from u.

Error occurs due to.
all references to 'dynamic-link library' discarded by /OPT:REF

The linker discarded all packaged functions that referenced exports in
dynamic-link library. As a result, dynamic-link library is not needed for
execution of the image.

You may want to consider removing references to dynamic-link library to
speed up the build.

Other occurrences of this warning can occur if an unused function in your
code references a .dll export that the linker has discarded. Use /VERBOSE
to see which of your functions the linker is discarding and then remove
them from your code.

for more details just go through MSDN and see how to use /VERBOSE

No reason to worry... linker just says that as you dont need anything from these two files so the references to them are removed.

;) Just researched that myself...

If it seems to cause you trouble in in your application tho its unlikley you can remove the /OPT:REF parameter from linker options and this optimization does not occur.

Please do not post the same question in multiple forums. Thank you.

Well, the program crash has some other reason. BTW, you should include "stdafx.h" before any other file.

You're sure this linker warning is related to the runtime crash?

The LNK4089 is just a warning telling you that you've referenced a library (you've told the linker too link a library), but the library is never used (no part of your code is using the library).

You should remove the library(-ies) from your project if you don't use them.
