I'm using Eclipse 3.4 (Ganymede) with CDT 5 on Windows.
When the integrated spell checker doesn't know some word, it proposes (among others) the option to add the word to a user dictionary.
If the user dictionary doesn't exist yet, the spell checker offers then to help configuring it and shows the "General/Editors/Text Editors/Spelling" preference pane. This preference pane however states that "The selected spelling engine does not exist", but has no control to add or install an engine.
How can I put a spelling engine in existence?
Update: What solved my problem was to install also the JDT. This solution was brought up on 2008-09-07 and was accepted, but is now missing.
