ImageMagick conflict on Ubuntu running webbrick

Question

Hi all

I am trying to install refinerycms, a Ruby on Rails CMS on Ubuntu 10.04 LTS. I run rails server and I get the following exception:

carcher@carcher-laptop:~/Code/tgc$ rails server
=> Booting WEBrick
=> Rails 3.0.0 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach

I built and installed ImageMagick 6.6.4 from source following the instructions here and BEFORE I did that I removed the ImageMagick tools that were pre-installed in Ubuntu, to avoid any conflicts. But still I seem to have this version 6.5.7 around.

I guess my question is how do I remove/disable ImageMagick 6.5.7-8?

Thanks in advance for the help, I'm all out of ideas.

Cheers, Ciaran.

Answer 1

Lots of help at the Refinery Google group: http://groups.google.com/group/refinery-cms. Or have you tried that already?

Answer 2

Hi all

I'm up and running! I did a clean Ubuntu install, and just used the pre-installed Imagemagick package. The Refinery CMS tutorial for Lunix omits a few things a novice like me needs to do, so I documented all my steps here.

The main problem was that early in the process when I ran into an issue with RMagick, I presumed I needed a later version of Imagemagick so I downloaded and installed it from source. There is no need to do that - none at all. The version 6.5.7-8 will do just fine and play well with RMagick and with RefineryCMS.

Hope this helps others.

If you need to use the latest version then I found this post that might help. I haven't tried it though:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557778

I posted this info on the RefineryCMS Google message board too.

Cheers, Ciaran
