ubuntu, ruby and log4r

[jansenh]

Hi Forum.

Not sure where this issue belongs... but anyhow: My Log4r ain't working

1 . I installed ruby-1.8.5 from source in /usr/src. (based on some blog recomendation...)
2. I installed rybygems-0.8.11 in /usr/src/

Both are working - I did a 'sudo gem install log4r' and the package installed itself.

3 . But using Log4r inside my ruby scripts is NOT working.


When I search for the Log4r files, I find them in /usr/local/lib/ruby/gems/1.8/gems/log4r-1.0.5/

And from here I do not know how to proceed? I haven't been arond linux in years :confused: Anyone want to help me?

I may not be able to give you the best advice as I'm only getting started with Ruby myself, and using gem never seems to work for me.
First try:

$irb
irb> require 'log4r'

If it doesn't return true then Ruby isn't finding the module. This is what happened me, so I downloaded the source extracted it and ran


$sudo ruby install.rb
$irb
irb> require 'log4r'
=> true
irb> include Log4r
irb> mylog = Logger.new 'mylog'
irb> mylog.outputters = Outputter.stdout
irb> mylog.debug("hello world")
DEBUG mylog: hello


If you get that far your laughing.

When you use a gem installed by rubygems in a script, you need to



require "rubygems"


before you require the gem you are using.

Thanks for that info Jessehk, it made me think and after a quick search I found this (http://docs.rubygems.org/read/chapter/3#page70) from the ReubyGems manual which shows that method plus better alternative methods.
