I've tried compiling the SVN version of OSG 2.9.9 on both Mac OS 10.5 and 10.6, and it appears that there is an issue with Qt 4.6.3. There are a number of errors during linking.
For now, a workaround for the build is to go back to an earlier version of Qt, it appears that version 4.5.2 compiles and links just fine. As a note, the easiest way to uninstall a more recent release of Qt is to run 'sudo /Developer/Tools/uninstall-qt.py'. Hence this post is partly a heads up to flag the problem with Qt4.6.3 so that it can be fixed in time for the 3.0.0 release (and please note that Qt4.7 is in release candidate stage). I have found a problem though with the examples. With osgviewerQtContext and osgviewerQtWidget, I am was getting errors such as 'Warning: Could not find plugin to read objects from file "cow.osg"'. These errors don't appear with osgviewer or osgconv. A fix for this was the following line: export DYLD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib/osgPlugins-2.9.9 I've been careful to set the paths and environment as described in section 4 of 'http://www.openscenegraph.org/projects/osg/wiki/Support/GettingStarted' (which perhaps should be updated for Mac OS X 10.5/10.6 as these use bash). The Qt examples programs seem to have problems with 10.5.8, OSG2.9.9 and Qt4.5.2: osgviewerQtContext - works best, does load 5 models into two windows (no other GUI drawn) osgviewerQtWidget - nothing is redrawn and only mouse events are printed in terminal; no widgets are shown osgQtWidgets - crashes upon start (bus error) osgQtBrowser works for only a short time (crash), but it does display a youtube page for a short time If you have any suggestions on what could be done to get the Qt examples running better under OS X, it would be very much appreciated. A few other miscellaneous notes: The README.txt section 'Release notes on OSX build' is a little out of date, as the XCode support has been deprecated. I realize this is due to the fact that cmake on Mac now handles Frameworks and hence there is a single unified build after version 2.9.8. (At first I was trying to figure out where the XCode folder had gone...) Up until now, I've been using the 2.8.2 and 2.8.3 with XCode, and the build here worked just fine. I couldn't get the 2.9.8 XCode project to compile (GCC_VERSION was set to 4.0) in either 10.5 or 10.6, but this point is moot, as the command line unified compile and frameworks support has taken care of this issue.
