I have Qt Creator on my mac. I downloaded the Qt sdk sources, I built them, and I am able to compile code for mac and it runs fine.
I would like to target Windows, so I downloaded mingw32 sources, I built them, and now I have a i386-mingw32-g++ executable that compiles c++ code just fine, and the binary executable compiled from my mac runs just fine on a Windows box.
I would like now to create a new build configuration in Qt Creator so that it will use mingw32 as the compiler, in order to generate Windows binaries.
Here's what I got in the Tool Chains configuration window:
Here's what I have in my build configuration:
As you can see I am not able to select mingw32 as the compiler. Why?
It's because your Qt libraries are Mac version. Creator knows the target platform of selected Qt install and shows only the tool chains that work with it.
I don't know how you can install a Windows version of Qt on a Mac. The installer obviously won't work. The only possible path is to build Qt with mingw that you have built.
Edit: Here's some info on cross-compiling Windows libs: http://lists.qt.nokia.com/pipermail/qt-interest/2011-March/031945.html
