The GTK2 stack is going to be updated to newer versions tonight. I will try to make it as seamless as possible. But if you have the current version of gtk+-2.tcel in your /tce directory , you will need to replace it with the new libraries. Here are the extensions that are replacing gtk+-2:
gtk2.tcel
atk.tcel
cairo.tcel
pango.tcel
pixman.tcel # pixman-0.14.0 will become pixman with this change.
If you are running in PPR mode with tcz/tce, simply remove the gtk+-2.tcel extension and replace it with the 5 mentioned above and all is good. If you are using PPI, you will need to remove the installed gtk+-2.tcel. Using the tce-uninstall utility would do that with this command:
tce-uninstall gtk+-2
You do not have to replace any apps that use gtk2 as they are compatible with the newer version. I hope that this will go smoothly and not interrupt anyone's use of TC. I will update the info files of existing extensions, and new extensions can be build against the new gtk2 stuff and the 5 extensions mentioned above will be the dependencies taking place of gtk+-2.tcel. Let me know if there are any questions or concerns.
