Hello,

On Windows XP, I got a ruby program using RMagick and working perfectly.  
I put this at the begining of my code:

```
require 'rubygems'
require 'RMagick'
include 'Magick'

```

Now, when I use the exact same code within Rails, I can’t have RMagick  
working… It seems it’s not initalizing. The include ‘Magick’ returns  
“undefined method `include’” Without the include, I got a “dynamic  
constant assignment” when I use an Image or ImageList.

I tried also to remove require’rubygems’ which I think should not be  
necessary in Rails.

I know there’s been tons of post regarding RMagick installation before,  
but what puzzles me is it seems to be correctly installed… For  
instance, it does appear when doing a gem list…

Any idea?

In my app, I simply have require ‘RMagick’

I create new objects like so: Magick::Image.new

I think preceding Image.new is necessary because the class that I am  
calling from is named “Image” anyway? I’m not sure. Anyway, that works  
for me.

I’m not sure why it’d be giving you the “undefined method ‘include’” but  
the  
proper include is:

include Magick

without the quotes. It’s not including a file but in fact telling Rails  
to  
mixin the methods of the module Magick [in the RMagick library]. I’d  
recommend mixing these methods in only in whatever specific class you  
plan  
on implementing RMagick in.

Also, I tried out the quotes around Magick in the include and got a  
different error than the one you’re talking about. I got “wrong argument  
type String (expected Module) (TypeError)”, which makes sense because of  
the  
reason I said above.

Hope all that helped.

RSL

Oops, actually, I put

require ‘RMagick’  
include Magick

(without the quotes) in my code, already…
