Linux Ubuntu  
Ruby 1.8.6  
Rails 2.0.2  
ruby-debug 0.10.0  
mongrel 1.1.3

Installed the ruby-debug gem, no problem, it also installed  
ruby-debug-base as a dependency

added deb"ugger to a line in a controllor

started mongrel  
brought up web page in firefox that would call the function in the  
controllor that has debugger in it. The browser hangs indicating it has  
hit a breakpoint

the console then displays

/home/scott/NetBeansProjects/webmonitor/app/controllers/driller\_controller.rb:14  
@drillerschoice = “choice”

which is right after the line with “debugger”

I get no (rdb:xx) debugger prompt and if I press any key I get a  
message that mongrel has stopped.

in the development log

nothing in the log to indicate a problem?

any ideas whats up?

Scott

I added Debugger.start after the  
require “ruby-debug”

and it works now

Is that normally required?

Is there another way?
