Hi - My Qt app, which uses shared libs (gui, core, network and webkit) ends up as a 17mb installer on Windows (comprising my app binary plus the Qt dlls and image plugins), built with VC2010.

I now do a Mac version. Using the standard Qt 4.7.1 distribution (for cocoa) on my Mac (Mac OSX 10.6.6) with Xcode 3.2.5 (ie using the prebuilt Qt from nokia, not one built by me). I build the app in totally standard way (qmake, then build in Xcode). I then use macdeployqt with -dmg option and get a .dmg file. Thats all fine and it works.

But the dmg file is 44 mb big, ie almost 3 times bigger on Mac than the same program for Windows.

Any ideas how to make for a smaller binary distribution on Mac?

Thanks.

PS I am definitely building in release mode.
