Due to my QtXml prebinding difficulties with Qt 4.3, I reinstalled Qt 4.2.3, recompiling from scratch. I regenerated a new Xcode project file using qmake -spec macx-xcode, and now QtXml links and works ok as before.
It would be nice to know why my 4.2.3 links properly but 4.3 does not. But failing that, my question is this: for MacOS, does anybody know exactly where the Qt settings are? Is there a QTDIR environment variable somewhere? My local .profile sure ain't it.
Even after reinstalling 4.2.3, Qt Assistant and the Qt Demo programs in the Developer/Applications folder still think I'm using 4.3. I need some clarity as to where, on MacOS, is everything supposed to go and who points to what and how.
Can I have 4.2.3. and 4.3 [and 4.3.1 and 4.4 and as many snapshots as I want] installed, and simply change some environment variables somewhere to tell all these programs where the preferred version of Qt I want to use is located? It takes hours to recompile everything, and this surely this is overkill. I have read everything I can find on the subject over and over and this info just seems to be obfuscated.
