ultimately, lqt_png.so should probably be linked against libpng, but some platforms may not allow linking shared libs into modules, or may not be able to resolve recursive inter-library dependencies at run time (a needs b needs c needs d). this should really be an issue for 'lqt-config --libs' or 'pkg-config --libs libquicktime', and whoever builds the libquicktime package, to make sure those commands give the needed linking arguments. -- [EMAIL PROTECTED] SDF Public Access UNIX System - http://sdf.lonestar.org
