Installing ECB in emacs 24 in ubuntu

Question

I understand from this question that CEDET is installed in emacs 24 without additional installation, so I don't need to follow those instructions here, or the CEDET part here.

I am not using the emacs starter kit, like this answer.

So, when I use elpa to install ecb, I get the following error:

Compiling file /home/mittenchops/.emacs.d/elpa/ecb-20131116.1319/ecb2/jn-file-tree.el at Mon Dec 30 16:13:57 2013

Another answer pointed me to this repository, which has jn-utils. Can I just drop these files into my emacs.d/elpa/ecb-20131116.1319/ecb2/ directory to replace the existing jn-utils?

In general:

1. Why is this failing?
2. How can I fix it and install ECB as simply as possible in emacs 24?

Answer 1

I just installed ecb in under a minute.

1. From bash:

   cd ~/git && git clone https://github.com/alexott/ecb
   

2. In ~/.emacs:

   (add-to-list 'load-path "~/git/ecb")
   (require 'ecb)
   

Done. ecb-activate brings up the code browser.
