if you downloaded a rpm, you do not need to compile codeblocks anymore. You do however need to install wxwidgets. Yast should probably detect this automatically, if not just start Yast and add the wxwidgets libraries.
Do you run a 32bit or a 64bit suse? The rpm is most likely for a 32bit system. If you have a 64bit system, it is possible to use the 32bit rpm by changing a couple of libraries. However, in that case I would suggest that you build the svn version
