whoops, found the bug. I forgot to move the Windows-specific headers to the
include directory.

Please re-download from
http://www.netegrate.com/index_files/download/SqlServer/

Make sure the include statements in your test application read as follows:

#include <config.h>
#include <stdarg.h>
#include <stdio.h>
#include <assert.h>
#include <stdlib.h>
#include <sqlfront.h>
#include <sqldb.h>

Also, please add the path to the unzipped include folder to the config
settings in VC10 of your sample application.

Thanks for that.

This version "breaks" my Visual Studio test app (it crashes upon calling
dbopen).

I think it's exactly the same behaviour I was getting...



I'm afraid it also doesn't work at all from Qt.

It's like it doesn't understand at all these libraries.

Are you really supposed to share libraries between compilers? I'm sure I had
read somewhere that this is something that cannot be done (different formats).



My build output is the following:
