Rachel, First of all, you will have to apply this patch for Plugins to work https://bugs.webkit.org/show_bug.cgi?id=14750
And this patch currently supports only GTK/X11. no GTK/DFB ! I have got a basic gtk-plugin .. No Drawing .. just printfs .. started to work just a few hours ago .. I have attached the file here (main.c) .. It has been adopted from the Mac Version 1. Create a Directory "TestNetscapePlugin" under /WebKitTools/DumpRenderTree/gtk/ 2. Copy attached main.c to this new directory WebKitTools/DumpRenderTree/gtk/TestNetscapePlugin/ 3. Attached "plugin_build.sh" I use this to build the plugin .. to work around Makefile.in issues As i told you this plugin is very very basic Once my sample plugin is up to some shape .. i plan to submit a patch with a complete GTK plugin sample .. may take a week or so Also .. you will require this HTML snippet to test your plugin <object url="/home/sriram/my_patch.txt" width="100" height="100" type="application/basic-test-plugin"> <p>Sample plugin installed and running ? </p> </object> Happy pluging Sriram On 4/17/08, Darin Adler <[EMAIL PROTECTED]> wrote: > > On Apr 17, 2008, at 8:40 AM, R Bassett wrote: > > I've got a directfb / gtk / webkit software stack cross-compiled and > > running nicely on my platform.
