Uninitialized constant ApplicationController?

Hello list,

I’m trying to start my Rails server after doing a long complex switch
from Postgres to MySQL, and I’m getting the following error:

=> Booting WEBrick…
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/dependencies.rb:200:in
const_missing': uninitialized constant ApplicationController (NameError) from script/../config/../vendor/plugins/user_engine/lib/user_engine.rb:74:inincluded’

… 10 levels…
from
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/server.rb:28

I’ve seen the ‘Uninitialized constant …’ message before, but it’s
always been because of a simple typo on my part, or a version mismatch
somewhere. I’m on Gentoo Linux, MySQL 5.0.18, Rails 1.0, current
versions of login_engine and user_engine, and that combination of
versions seems to be fine as far as I can tell.

Any suggestions where to look?

Thanks in advance

Dave M.

Make sure the app/controllers/application.rb file exists.

Thanks Hasan,

I checked that it is there, appears to be correct, but the problem is
still occurring.
