Hi again, I now compiled GEGL against SDL. I keep getting the same error. Did you notice this line?: GEGL-geglmodule.c-Message: Module 'k:/daten/programmierung/libraries/gegl-0.2.0\ gegl\.libs \libgegl-0.2-0.dll' load error: Missing gegl_module_query() symbol I guess it has nothing to do with the gegl:display op, but this might be the reason why it wouldn't find any display op.
