Although I haven't specifically done this yet, here would be one way to do it: Build and install Qt in two separate locations for GCC 3.3 and 4.0, using "sudo gcc_select 3.3" and "configure -prefix /usr/local/Trolltech/Qt-4.1.2/gcc-3.3" for GCC 3.3 and the equivalent for GCC 4.0. (You can probably do this without using gcc_select, but I haven't taken the time to figure out how.) Use "cp -R" to make a copy of one of the frameworks (say /gcc-4.0/libs/QtCore.framework). Run "lipo /some/path/<strong>gcc-3.3</strong>/libs/QtCore.framework/Versions/4.0/QtCore /some/path/<strong>gcc-4.0</strong>/libs/QtCore.framework/Versions/4.0/QtCore -create -output /some/path/<strong>universal</strong>/QtCore.framework/Versions/4.0/QtCore". From there follow the steps described in Trolltech's article on <a href="http://doc.trolltech.com/deployment-mac.html" rel="nofollow">Deploying an Application on Qt/Mac</a>. As always, I suggest you integrate this into your build script! Let me know how this works, as I haven't actually given this a try.

Although I haven’t specifically done this yet, here would be one way to do it:

Build and install Qt in two separate locations for GCC 3.3 and 4.0, using “sudo gcc_select 3.3″ and “configure -prefix /usr/local/Trolltech/Qt-4.1.2/gcc-3.3″ for GCC 3.3 and the equivalent for GCC 4.0. (You can probably do this without using gcc_select, but I haven’t taken the time to figure out how.)

Use “cp -R” to make a copy of one of the frameworks (say /gcc-4.0/libs/QtCore.framework).

Run “lipo /some/path/gcc-3.3/libs/QtCore.framework/Versions/4.0/QtCore
/some/path/gcc-4.0/libs/QtCore.framework/Versions/4.0/QtCore -create -output /some/path/universal/QtCore.framework/Versions/4.0/QtCore”.

From there follow the steps described in Trolltech’s article on Deploying an Application on Qt/Mac.

As always, I suggest you integrate this into your build script!

Let me know how this works, as I haven’t actually given this a try.

Do you have any hints on building the 3.3/ppc and 4.0/intel Qt Frameworks and lipo-ing them together? Nice entry.
