Hello, I am newbie so please excuse me if i am asking childish thing. So now the point is i have already working GTK of version 1.2 something. So now i tried to upgrade it by installing gtk 2.20.0. So i followed needed procedures. Installed latest pkg-config, lib png 1.4.x, freetype, fontconfig, glib, pango atk, laterward tried cairo 1.8.8, while configuring i faced following problem /opt/newgtk/ is my directory for new gtk tried to keep separate from older version linux:/opt/newgtk/cairo-1.8.8 # ./configure --prefix=/opt/newgtk/ . . . . . . . checking for cairo's PNG functions feature... configure: WARNING: Could not find libpng in the pkg-config search path checking whether cairo's PNG functions feature could be enabled... no configure: error: recommended PNG functions feature could not be enabled But i have already installed linpng then also why i am facing this problem dono i have libpng 1.4.X but my cairo is 1.8.8 Is there any version incompatibility is there between these? So can a kind soul tell me what my problem is? Thanks & Regards, Guruprasad. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
