For those who are going to install RMagick on Windows this might help you.
Actually I've spent half day making this work and as I was googling around I found this usual reason why it doesn't work (most of them are my typo fault):
- This application has failed to start because CORE_RL_Magick_.dll was not found Re-installing the application may fix the problem....RMagick2.so
irb(main):002:0> require 'rmagick'- This error occurs because "you don’t have ImageMagick path in your PATH!". So better change or add it on your PATH.
LoadError: 126: The specified module could not be found.
from c:/ruby18/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require’
- Runtime Error!
Runtime Error!- comes out becuase your VC++ version is not compatible with the version of RMagick
Program: c:\ruby\bin\ruby.exe R6034
An application has made an attempt to load the C runtime library incorrectly.
- This application has failed to start because the application configuration is incorrect. Re-installing the application may fix the problem....RMagick2.so
- something's wrong with your installation. Re-install it.
