Emacs 24.3.1 and ECB 2.40 Error: ECB can only be used with cedet [1.0pre6, 1.1.9]

Question

Running Ubuntu 12.10 with Emacs 24.3.1 and ECB 2.40. Not sure what actually caused this, other than an apt-get update && upgrade I ran a couple days ago.

It started when I rebooted my computer and I ran Emacs and did M-X ecb-activate I would get the following error:

ECB 2.40 - Error: ECB can only be used with cedet [1.0pre6, 1.1.9]! Please install it and restart Emacs!

I tried a couple of things but have not figured out what exactly caused this issue. I did an apt-get update && upgrade several days ago IIRC and it did update a bunch of packages, so thats a possibility. I ran M-X cedet-version and got:

 CEDET Version: 2.0
            Requested   File        Loaded

  cogre:        1.2     nil     Not Loaded
  cedet-contrib:    1.2     nil     Not Loaded

Any thoughts on what is going on here?

What worked for me (after some more googling) was to edit ecb/ecb-cedet-wrapper.el - find the following line in that file: (defconst ecb-cedet-required-version-max '(1 1 4 9) And replace the first '1' to a '2': (defconst ecb-cedet-required-version-max '(2 1 4 9) Restarted emacs and everything is working fine. – Boleyn

please, look to my answer about fresh versions of ECB/CEDET – Estrade

Answer 1

There is a fork of ECB that works with fresh Emacs & CEDET versions. You can install it either manually, or via MELPA (see instructions on the end of page on how activate MELPA).

(defconst ecb-cedet-required-version-max '(1 1 4 9)

And replace the first '1' to a '2':

(defconst ecb-cedet-required-version-max '(2 1 4 9)

Restarted emacs and everything is working fine.

Or under ecb-2.40/ecb-upgrade.el for the same const. – Flagler

Thanks for the info, not using ECB anymore too many moving parts for what I wanted. – Boleyn

Answer 3

After a LOT of googling, the only trick that did it for me was found here : add

(setq ecb-version-check nil)

to my emacs init file.
