Autoloading failed to define function semantic-mode

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?

This may be a config problem.  When you used CEDET from sourceforge, 
it's configuration must be the first thing in your .emacs.  If any other 
code starts loading in CEDET from Emacs core, you will get a missmatch 
like this.

This error is from an autoload claiming to provide semantic-mode in some 
file, but it doesn't exist in CEDET from sourceforge, as that is a new 
Emacs only feature at the moment.  If you get CEDET setup first, then 
you can avoid other code trying to use semantic-mode.

Sometimes, this might be because of a default.el or other system wide 
config file.

require: Symbol's function definition is void: eieio-defmethod

Trying to run `M-x semantic-mode` gives me the following error:

  require: Symbol's function definition is void: eieio-defmethod

I'm currently on:

  GNU Emacs 23.4.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.10)

CEDET Version:	1.0
  			Requested	File		Loaded
  Package		Version		Version		Version
  ----------------------------------------------------------
  cedet:		1.0		nil		ok
  eieio:		1.3		ok		ok
  semantic:		2.0		nil		ok

I cannot find any mentioning of eieio-defmethod anywhere in my site
files and trying to build cedet from sources fails with the same error
messages.

Any idea what causes this and how to fix it?

Cheers,
Philipp Moeller

How to enable semantic-clang?

I noticed that there is a bovine/semantic-clang.el in CEDET 1.0. How can I enable and use this for code
completion? Is the semantic-clang-binary customizable? My clang does not reside in /usr/bin.

Best regards,

Arne

Re: How to enable semantic-clang?

Ok, I just set the variable in my init.el and did semantic-clang-activate. Now the module works, but not
quite well. Several symbols can't be completed. I guess I have to setup some more paths and/or variables?
What do I need to set so that my whole project is being scanned for possible completions?

Best regards,

Arne

Re: How to enable semantic-clang?

I had a look, and the module looks very early in development. Afaik no project settings for paths are passed
down.

How to set up EDE include search paths

I am trying to figure out how ede works, so that I can use the semantic-clang.el better. It seems that it uses
the ede facility to look for source files. My projects are rather large, but follow a regular structure:

Source files reside under $PROJECT_ROOT/modules/*/src/*.cc.

Header files reside under $PROJECT_ROOT/modules/*/include/*/*.h.

Can I teach ede to look under these paths automatically for source and header files?

Best regards,

Arne

Use a ede-cpp-root project. For the docs see

(info "(ede) ede-cpp-root")

Include directories and preprocessor symbols from projects are passed to
clang.
