[Qt-interest] a question about QLibrary

[Constantin Makshin]

It works here.

Try loading the library with native API. On Windows you can do something  
like this:

#include <stdio.h>
#include <windows.h>

int main (int, char**)
{
     printf("Trying to load A.dll ...");
     HMODULE dll = LoadLibraryA("A.dll");
     if (dll)
     {
         printf("   SUCCEEDED\n");
         FreeLibrary(dll);
     }
     else
         printf("   FAILED\n");
     return 0;
}

If native functions successfully fail to load your library, the problem  
isn't in Qt. Moreover, if it was a Qt bug, I'm sure it would have been  
already fixed.
