Hi there. I found a bug in osgdb_qt.so for the latest FlightGear/cvs. The problem is that fgfs crashes when loading Textures/Sky/broken.rgba for the aircraft that have a non-rgb (say png) splash image.
I made a patch to solve this problem, and I already sent to an OSG developer. I hope it will be applied to svn soon. Until the next binary package is delivered, I recommend mac users who use FlightGear-cvs-bin-20080918 update the plugin called osgdb_qt.so. The plugin is available from: http://macflightgear.sourceforge.net/wp-content/uploads/plugins/osgdb_qt.so To update the plugin, follow the instructions below: 1) Open /Applications folder on Finder 2) Control-click (or right click) the FlightGear icon and select "Show Package Contents" 3) Browse Contents/Resources/plugins folder 4) Copy (overwrite) the downloaded osgdb_qt.so to the plugin folder I'll explain the problem for developers and curious users. The problem is that QuickTime cannot handle gray-scaled rgb files properly (QuickTime complains BadData error even it is not bad at all). On Mac OS X, both osgdb_qt and osgdb_rgb plugins can handle rgb files. osgdb_rgb handles only rgb(sgi) image files but osgdb_qt handles many image files like rgb, png and jpg through QuickTime functions. In case that osgdb_qt is already loaded for handling some image files it also handles rgb files instead of osgdb_rgb, otherwise osgdb_rgb is loaded to handle these. So this problem occurs only when an rgba file is being loaded after a png (or some other type of image) file is loaded by osgdb_qt.so. Thus, on Mac OS X, the latest FlightGear/OSG crashes while loading aircraft that have png files for splash image or textures. The best way, I believe, is to delete the code that let QuickTime handle rgb files since these files can be handled (and more properly) by osgdb_rgb. Thanks goes to Scaba. The assumption he told me in IRC was right, and it helped me find this bug much quicker.
