I tried to configure UAE with the following options:
./configure --enable-ui
But I get an error who states that it wasn't possible to configure UAE with all the selected options. As I went to the output which was generated by the configure command I found a line who states, that gtk+ is not available and therefor the userinterface won't be configured.
So I went to yast to checkout wether gtk+ is installed and it is. I also installed the development-package for gtk, but it didn't help.
If somebody could help i would really appreciate it.
