Well, the most obvious error is that there is no initial '#' character on the line where you try to include libgimp/gimp.h. (Have you never programmed in C before?) It should look like this: #include "libgimp/gimp.h" You also need to have the PLUG_IN_INFO array and MAIN(). Add the following to the bottom of the source file: GimpPlugInInfo PLUG_IN_INFO = { NULL, /* init_proc */ NULL, /* quit_proc */ query, /* query_proc */ run, /* run_proc */ }; MAIN () The menu path to the plug-in that is passed to gimp_install_procedure() needs to start with <Image>. Change it as follows: gimp_install_procedure ( "plug_in_hello", "Hello, world!", "Displays \"Hello, world!\" in a dialog", "David Neary", "Copyright David Neary", "2004", "<Image>/Filters/Misc/Hello world...", "RGB*, GRAY*", GIMP_PLUGIN, G_N_ELEMENTS (args), 0, args, NULL); } With these changes your plug-in compiles and works fine with GIMP 2.2. --tml _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
