The first is that you also need the wxWidgets-2.8.7-packages to fullfill the dependencies of the binaries.
You can have a look at my server (see signature) for a description how to get them.
From the wxWidgets-2.8.7 packages you need at least "libwxbase2.8-0" and "libwxgtk2.8-0".
If you want to develop wxWidgets-applications, you also need "libwxbase2.8-dev", "libwxgtk2.8-dev", "wx-common" and "wx2.8-headers".
The wxWidgets documentation is in the "wx28-doc"-package.
If wxWidgtes is installed you can do a minimal installation (without wxSmith and contrib-plugins) with
dpkg -i codeblocks_8.02_i386.deb libcodeblocks0_8.02_i386.deb
You should also install "codeblocks-contrib_8.02_i386.deb" and "libwxsmithlib0_8.02_i386.deb" (add them to the commandline above).
The C::B -dev and -dbg packages are normally not needed.
If you have any questions feel free to ask.
