Hi,

thanks first of all. Yeah, that´s what the compiler says (well, actually 
it says that they are not defined not that the lib cannot be found) but 
what is the reason for it?
All the 32bits libs are in the same directory. Just as all the 64bits 
libs are in the same directory and the system libs are definetly 
available in both directories (all possible configurations in there even 
the dlls...hehe, just to be sure) and the directory is correctly set in 
the project settings (for both), just that the 64-bit built works and 
the 32-bit one doesn´t. That is why I am stuck here. What could be the 
reason for it not finding the definitions in 32-bit but in 64-bit? That 
kind of doesn´t make sense. The system lib is definetly there.
