I use Lablgtk and all functions except the function "GdkPixbuf.from_file" work well. I can compile the code including the function "GdkPixbuf.from_file", but I can't execute it. When I type the command "./programname" to execute it, I get an error: 

Fatal error: exception GdkPixbuf.GdkPixbufError(3, "Couldn't recognize the image file  
format for file 'filename.jpg'")

The code which doesn't include the function "GdkPixbuf.from_file" can be executed. What should I do to make the function "GdkPixbuf.from_file" work well?

It looks like that your GdkPixbuf doesn't support jpg files. You can either convert your image file to another format, like:

convert filename.jpg filename.png

Or you can try to install supporting modules. Some more information can be found here

  • I convert filename.jpg filename.png, but I get error. – mmsss Aug 01 '14 at 13:23
  • I read the linked page in "Some more information can be found here". – mmsss Aug 01 '14 at 13:25
  • Oh, my comment is on the way. Sorry. – mmsss Aug 01 '14 at 13:26
  • First, thank you for your comment, ivg. In the linked page, I can't get the information to solve the error. I thought the command "gdk-pixbuf-query-loaders --update-cache" solves the problem and tried, but it could't solve the problem. Do you have any ideas? – mmsss Aug 01 '14 at 13:35
