While trying osgEarth (great work by the way), I find a OSG problem. osgEarth works correctly with osgviewer but not with our own viewer. After some investigations with the debugger, it was because we are loading a png file before loading the earth file. And then when osgEarth try to load distant png files, it calls the method osgDB::Registry::read. It tries first to load with existing loaded plugins. So it tries with osgdb_png plugin that returns a FILE_NOT_FOUND. Finally, the method returns a FILE_NOT_FOUND because the curl plugin is not yet loaded and will never be... the code to load it is just after the FILE_NOT_FOUND return... Surely, other image plugin have the same behavior, it is not only a png problem.
I have made a small modification to osgviewer to reproduce the problem, just loading a png file at line 46. With this line, loading google_maps.earth does not work, comment it and then it works... I think of different ways to fix that: - modify the Registry::read method to handle file with server adress differently - modify each image plugin to return a FILE_NOT_HANDLED when the file name contains server adress - force to load the curl plugin at the start somewhere in my code... or maybe in osgDB Not sure which is the best?
