Hello Rails, I have a problem.
I would like to use captcha in one of my project. When I did try to
install, this is what I got
$ sudo gem install captcha
Building native extensions. This could take a while…
ERROR: Error installing captcha:
ERROR: Failed to build gem native extension.
/usr/bin/ruby1.8 extconf.rb
extconf.rb:1:in `require’: no such file to load – mkmf (LoadError)
from extconf.rb:1
Gem files will remain installed in /var/lib/gems/1.8/gems/
rmagick-2.12.2 for inspection.
Results logged to /var/lib/gems/1.8/gems/rmagick-2.12.2/ext/RMagick/
gem_make.out
Could any one help me out on this?
Looks like you are missing the tools to build the extensions. If you
are on a Debain based distro, try
sudo apt-get install build-essential
If that doesn’t work, search for guides on installing rails on Debian
systems.

Sorry, can’t help much there. I’m still learning Rails and find that
building my own instead of using plugins helps me grok things better.
Like rolling my own authentication and authorization.
For example, instead of captchas for user validation, I use a simple
email challenge. Of course that meant I had to learn ActionMailer, but
that’s built in.

Got captcha installed. But when I tried ( refering
http://rdoc.info/projects/zendesk/captcha )
$rake captcha:generate COUNT=250
It gave the following output
rake aborted!
Don’t know how to build task ‘captcha:generate’
This is looking like rocket science to me.
Has any one else run into the following problem?

Thanks a lot! Thanks to all who have taken pains to answer this
question. I found perfect solution in
http://www.codeandcoffee.com/2007/06/implementing-a-captcha-with-ruby-on-rails-in-10-minutes-or-less/
. I haven’t tested catchcaptor.com , but it looks impressive.
Hope this discussion will be helpful to those who are having trouble
with captcha.
