I was trying to install the Aurora Gtk+ engine and the Ubuntulooks engine in Opensuse 11.1 64-bit (Gtk v. 2.10.0). Ubuntulooks comes with the .so and .la files precompiled, and I dropped those into the /usr/lib/gtk-2.0/2.10.0/engines directory, like it says in the installer. The theme I was trying to use didn't work correctly. I thought it might be an issue with the compiled files, so to test it out I downloaded the Aurora engine source and compiled it. The Aurora theme that comes with the engine still doesn't work. I checked and the Aurora.so and Aurora.la files are both in the correct directory. Is there something I'm doing wrong? Thanks in advance.
