ReaderWriterPNG.cpp is the source code for the osgdb_png.so plugin. Many of the OSG plugins rely on a 3rd-party library to do their work (the PNG plugin need libpng, the JPEG plugin needs libjpeg, etc.) The 3rd party libraries are listed here: http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies Since you're on a Linux machine, your Linux distribution should have packages for most of these. Be aware, though that there are usually two packages for each library. One just lets you run programs that use the library, the other lets you develop programs to use the library. You need the development one. Usually, these packages have a -devel or -dev suffix.

That's the one you want. Since you're also developing for Qt, you want to make sure you have the -dev version of the Qt packages installed, too. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=46266#46266 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
