[cedet-semantic] Autoloading failed to define function semantic-mode

[Jim F. <ja...@wa...>]

I've got two pretty much identical installations. One runs on a laptop 
and the other with Virtualbox on a Windows XP machine. Both systems are 
Ubuntu 11.1 and both have Emacs 23.3.1 installed.

CEDET appears to have installed and runs on the VirtualBox machine and I 
can select the very useful Semantic mode. I've not got to grips with 
compiling Arduino code with the EDE yet.

On the laptop, I can't get Semantic mode and get the error “Autoloading 
failed to define function semantic-mode”. Also the tick boxes for 
Semantic and EDE don't 'take' a tick.

Is there a 'fix' for this please?
