Linking against a .lib built from visual studio

[newbie43]

Hello all
I have qt5.4 installed on windows 2007 and I can build a simple hello world using the mingw compiler without issues. I also have some static ".libs" that i need to link against that were built with an older version of visual studio 2004 "msvc compiler" on windows xp. After I setup the .pro file to include all the .libs and paths I get udefined references no matter what I try. Next i tried a different route I have windows c++ visual studio 2010 installed so I installed the Qt plugin using the "msvc compiler version" and can create a simple qt5.4 project in it and it runs fine. But when I link in these static libs I still get undefined references. Is it even possible to link against these static libs with qt seeing how they were built under a different compiler? Thanks for any help.

This not related to Qt but C++ on Windows.
You need to build the libraries with the same compiler as the application.

Cheers,
