RE: gdk_pixbuf_new_from_file_at_scale() returning error saying Unrecognized image file format when loading png files
HI Alexandar, Thanks for your input. I tried installing shared-mime-info package. But still it is not working. Below is the snippet how I configure and build shared-mime-info and gdk-pixbuf: cd shared-mime-info-0.90 ./configure --prefix=$WLD make make install cd .. # As of 2012-03-14, gtk git is saying: # Requested 'gdk-pixbuf-2.0 = 2.25.2' but version of GdkPixbuf is 2.24.0 cd gdk-pixbuf ./configure --prefix=$WLD --without-libtiff # Is it worth grabbing libtiff? make make install cd .. Do I need to export any variable also?

Hi Alexander, There was some issue with the setting of XDG_DATA_DIRS which I could resolve. Thanks for your valuable inputs.

gdk_pixbuf_new_from_file_at_scale() returning error saying Unrecognized image file format when loading png files
Hi, I have built weston with wayland (wayland 0.85). When I try to run weston server it is loaded properly but the cursor is not displayed. When I dig into more detail and put some logs I could see that following functions are getting called: create_pointer_surfaces()-display_create_surface_from_file()-display_create_egl_image_surface_from_file()-gdk_pixbuf_new_from_file_at_scale(). Now, the function gdk_pixbuf_new_from_file_at_scale() is returning some error value with Unrecognized image file format which is resulting in error print Error loading pointer image.. I checked the mime database. The mime database is present in /usr/share. But I am installing and using my local directory for all my source code. My directory is /home/avijit/install/ and there is no mime database installed under /home/avijit/install/share. So, do I need to install the mime databse within my environment?? If yes, what is the procedure to do so? I checked the gdk-pixbuf loader in my environment (/home/install/lib/gdk-pixbuf/2.10.0/loaders) and it is using an external loader. The png loader file is also mentioned in loader.cache.
