Ruby can't see RMagick installed from gem on FC4

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
/usr/lib/ruby/gems/1.8/gems/rmagick-1.13.0/ext/RMagick/RMagick.so
/usr/lib/ruby/gems/1.8/gems/rmagick-1.13.0/lib/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?

Thanks,

Lance F. Squire

If you are using a library installed with gems, you will need to

require 'rubygems'

first. Give that a try.

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
things about RMagick

$ ruby -rrubygems -e "require 'RMagick'; puts Magick::Long_version;"

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...

Add explicit
require 'rebygems'
to your code then


require 'rubygems'
require 'RMagick'
include Magick
cat = ImageList.new("Cheetah.jpg")
cat.display
exit

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

Though you would think they would have included it....

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...

# locate ld.so
/etc/ld.so.cache
/etc/ld.so.conf
/etc/ld.so.conf.d
/etc/ld.so.conf.d/mysql-i386.conf
/etc/ld.so.conf.d/qt-i386.conf
/usr/lib/librpmbuild.so
/usr/lib/kde3/kded_kssld.so
/usr/share/doc/man-pages-ja-20060115/translation_lists/ld.so.translation_list
/usr/share/man/ja/man8/ld.so.8.gz
/usr/share/man/man8/ld.so.8.gz
