I'm planning on using RMagick to do thumbnails for a Rails project.
Installed RMagick using 'gem install rmagick'
Here are last few lines...

Successfully installed rmagick-1.13.0
------------------------------------------------------------------------
'post-setup.rb' error codes worry me...
Tried using it anyway as installation reported as 'successful' anyway.
Rails complained about not finding the methods.
tried testing the "require 'RMagick'" in irb.
------
LoadError: no such file to load -- RMagick
from (irb):1:in `require'
from (irb):1
------
tried the sample script from the 'Users Guide'
------
require 'RMagick'
include Magick
cat = ImageList.new("Cheetah.jpg")
cat.display
exit
-------
Results:
-------
Rmagicktest.rb:1:in `require': no such file to load -- RMagick
(LoadError)
from Rmagicktest.rb:1
-------
Checked locations of Rmagick.so and libMagick.so
-------
locate RMagick.so

locate libMagick.so
/usr/lib/libMagick.so
/usr/lib/libMagick.so.9
/usr/lib/libMagick.so.9.0.4
-------
No 'usr/local/lib/ to worry about...
Any ideas on where to look/ how to fix?

Try to run following line
ruby -rrubygems -e "require 'RMagick'; puts Magick::Long_version;"
what do you see??
Also you could read this article - you could find some interesting

Um... This is FC4 no sudo to worry about (there is a root account to
work from)
libs ARN'T in 'usr/local/lib' they are in 'usr/lib' (see top)
Running the irb or ruby tests above produce the same results under root.
Still stumped...

This dose make the test code from the 'Users guide' work.

Add explicit
require 'rebygems'
to your code then
require 'rubygems'
require 'RMagick'
include Magick
cat = ImageList.new("Cheetah.jpg")
cat.display

Yes, but I must 'su' for the 'gem install rmagick' to work properly.

Well, as Rails is working properly, and was installed the same way, I
presume that ld.so is pointing to 'usr/lib'
Can't find relevent ld.so to check...

that means you are compiling as root. if the installs uses non-standard
library paths (LD_RUN_PATH or -r switch to ld.so) they will then fail at
runtime as doing this as root is silently ignored.

Well, as Rails is working properly, and was installed the same way, I

rails doesn't require a properly configured ld.so since it uses now shared
libs

include RMagick
to:
require 'rubygems'
require_gem 'rmagick'
include Magick
strangly produces this message:
undefined method `include' for #<MyBountyController:0xb796d1d4>

no prob.
it looks RMagick compiled ok - otherwise you wouldn't have an so...
what do these commands do for you
harp:~ > ruby -r rubygems -e' require "RMagick"; p Magick '
Magick
if that doesn't work try
harp:~ > LD_LIBRARY_PATH=/usr/lib ruby -r rubygems -e' require "RMagick"; p Magick '

therefore, you've got it installed. if you are having issues with rails you
have issues with permissions or you have two rubys installed and the web users
is using a different one

that has to be on one line!
anyhow. you have installed RMagick and can use it fine from the command line.
what's your exact issue in rails then?

This may or may not have happened when I tried to upgrade the version of
rails.
Don't know how to check and or rectify...

Trying to use Rmagick to make thumbnails of images previously stored on
the drive.
You've seen the errors above. here is the code as it stands now:
def make_thumb(location, image, thumb)
require 'rubygems'
require_gem 'rmagick'
include Magick
pic = Magick::Image.read("#{location}#{image}")
imgwidth = pic.columns
imgheight = pic.rows
imgratio = imgwidth.to_f / imgheight.to_f
imgratio > aspectratio ? scaleratio = 64 / imgwidth : scaleratio =
64 / imgheight
thumb = pic.resize(scaleratio)
white_bg = Magick::Image.new(64, thumb.height)
pic = white_bg.composite(thumb, Magick::CenterGravity,
Magick::OverCompositeOp)
pic.write("#{location}#{thumb}")
end
