Script throws error whenever I require mysql gem


#1

Hi all,

Ive been working on a small script and Im about to place some
functionality into it which allows it to write to my database by making
use of activerecord. I’m hitting a brick wall at the moment so I’ve come
to you for your expertise :slight_smile:

The script runs perfectly fine until i…

require ‘mysql’

…even though I havent actually asked the script to do anything more
than connect to mysql. if i comment out the configure block the error
still occurs.

I thought mysql was the issue so i completely reinstalled it from source
and the same error still occurs.

heres the error im seeing on Mac OS X Tiger:

The script for anyone interested is simply as follows:

require ‘rubygems’
require ‘sinatra’
require ‘scrobbler’
require ‘twibot’
require ‘activerecord’
require ‘mysql’

#startup tasks
configure do
#connect to database
ActiveRecord::Base.establish_connection({
:adapter => “mysql”,
:database => “tuneme”,
:socket => “/tmp/mysql.socket”,
:username => “root”,
:password => “”
})
end

class Link < ActiveRecord::Base
end

reply do |message, params|

#create entry test

link = Link.create(:LinkValue => ‘123xyz’)

#check last.fm for a recomendation
message_content = message.text
artist_name = message_content.gsub("@tuneme ", “”)
p artist_name
artist = Scrobbler::Artist.new(artist_name)
#artist.similar.each { |a| puts “(#{a.match}%) #{a.name}” }
similar_artist = artist.similar.first.name
message = “@” + message.user.screen_name + " #{similar_artist} and
others… "
post_tweet message
end

I’m completely at a loss here… any ideas?

Cheers
Chris

OK, I’ve now done a complete uninstall and reinstalled with macports
instead. Now I’m seeing the following error:

LoadError: Failed to lookup Init function
