Inclusion of Qt Mobility classes slows project build to a crawl
We've just started using Qt Mobility in our project. I've built the Qt Mobility libraries we need and am trying to come up with a solid procedure to distribute them to other developers ( we'd rather not have to build the libs on each machine). I had some initial problems getting the Qt to acknowledge the existence of the Mobility APIs but got around that by including <QtSDK>/mkspecs/features/mobility.prf and mobilityconfig.prf in the distribution.

The state I'm at now is that I have a procedure to get developers up and running with the parts of QtMobility that we need. They can build with no problems and everything behaves as it ought to except in one respect: our builds are MUCH slower (~10x slower for a build from scratch). The weird thing is that builds from identical source on Ubuntu with Qt 4.7.4 / GCC have not been affected - it's just the building on Windows with Qt 4.7.4 / MinGW 4.4 which is noticeably slower.

Is anyone else experiencing massive slowdowns when including QtMobility and building with MinGW? Have I missed some important dependency and am causing Qt to be searching through a wider area than it should be? Give me your craziest ideas!

Cheers,

Sam
