You seem to be trying to intermix Visual Studio and Gnu. That is way 
more trouble than it is worth. The fact that your archive ends with 
.tar.gz suggests that it is targeted at 'nix operating systems. 
QtCreator uses the Gcc compiler in MinGW (Minimum Gnu for Windows). The 
file libdes.a that you created in QtCreator is a static library. If you 
build your application in QtCreator you can just link it in. Gcc will 
not create .dll or .lib files. Those are Microsoft shared library 
extensions. Shared libraries built with Gcc will have the extension .so. 
My advice would be to stick to QtCreator. You already built the library 
statically. Just compile your application with QtCreator and link in 
that library. You can link both static and shared libraries into an 
application
