I'm writing an application whose ultimate target platform will be Windows. But I'm developing in Linux because I really need to get more used to it.
So through Googling I found this article (http://silmor.de/39) on how to cross-compile. A got a little annoyed when I was searching for those source packages, since they're buried within subfolders of subfolders on MingW's sourceforge page. I then had an "I'm an idiot" moment when I realized I could just search through Ubuntu's repos.
Well, one thing led to another, and I found this repo source (https://launchpad.net/~clazzes.org/+archive/ppa) which seems to have exactly what I want. There's only 2 problems with it:
1) It compiles to Qt 4.7.0, which at the time of this writing, hasn't yet been finalized
2) It doesn't work
Now of course, the second point is more important than the first. :)
More specifically, here's what happens:
I run i686-pc-mingw32-qmake-qt4, which generates my Makefile. I then run make, and here's my output:
make -f Makefile.Release

There's no problem with the program; it's a barebones GUI app that compiles and runs fine natively on Linux.
Now, it's pretty obvious from the first error, the proper include path isn't present. Why is this? I would figure upon installation, the qmake.conf file would contain all the proper information.
I really don't want to have to manually edit my Makefile to add in all necessary include paths.
Is there some way I can fix this?
