Hi All,

I am using 'captcha gem' in my code to implement 'CAPTCHA' functionality
,It gives following error :

Hello,

do you require rubygems in your script, ie., do you have a line

require "rubygems"

before

require "captcha" ...

in your script ?
Maybe you can post some shortened bit of code ...

Best regards,

Axel

Well, from what you posted, require 'rubygems' is done somewhere in the code you load (that's the custom_require line right there) and I guess the captcha gem tries to load GD and cannot find it.
So your problem is either that GD is not correctly installed or that you don't have the correct GD version.
Try to isolate the problem by making a small unit test of just a test program that does only the one thing you're trying to do here:

require 'rubygems'
require 'captcha'

var= CAPTCHA::Web.new
p var.to_html("captcha_temp")

so that you don't have all the Rails snick-snack to wade through.

Also, here's a link to a discussion talking about the captcha gem http://groups.google.com/group/uso-dev/browse_thread/thread/63642201fb194e0d

I think it mentions that it needs the ruby-gd gem and that that gem is source-only (so you need to compile yourself)

Hello,

there is a dependency problem. The captcha gem wants to load
the GD library

(which is not written in Ruby).
You'll have to install that and probably one of the Ruby bindings
to GD.
From a search on Rubyforge, I gather that the Ruby gem GD is now
called ruby-gd.
As the captcha gem you're trying to install has its last release
on March 28, 2004 and the now-name-changed GD/ruby-gd gem releases only
one file, from January, 30th, 2007, there might have happened some changes
in the meantime, I'm afraid :frowning:

Maybe it's good idea to contact the author of the ruby-gd gem
to ask for help ... or use some other turing test gem, like turing.

Best regards,

Axel
