My Config.gcc has MONOLITHIC = 0 in it. Or is there another option that overrides this?
Yes, when building wxWidgets.
No inside codeblocks, but the wizard is normally only tested with MONOLITHIC builds, note it should asked you when running it if mono or multilib build. I have not used the wizard in months not sure if it asks you, but the forum implied it did after last redesign.
Edit added stuff I added late above
For Multi, Change wxmsw28 to wxmsw28_core and add wxbase28
Note, more libs may need to be added based on each project requirement.
Are you doing an Unicode build or not?
To change libs look at
Project -> Build Options
Change "Compiler Settings" to "Linker Settings"
The libraries should be under "Link Libraries" add them one per row.
