Compiling on different platforms

[Tori]

Hi, I'm new to QT and attempting to make a cross platform project. I have coded something on windows and am now trying to compile it on mac. Does any one know the correct steps to do this? I am creating a .pri file through visual studio, then transferring all files to the mac, running qmake -project, qmake, then opening up xcode and trying to compile. What am I doing wrong? It gets as far as linking then isn't happy. Thanks! (Using QT4.1 on both platforms)
