How to install rmagick gem on Windows?
How do I install rmagick gem for Windows XP? I already installed ImageMagick with the header files, and I installed RailsInstaller.org which comes with DevKit. I don't know where to look to fix these errors.

message SUMMARY
This is the contents of mkmf.log
checking for Ruby version >= 1.8.5... -------------------- yes
--------------------
I also have Cygwin and tried there, but encountered a different ruby related error. I can see a few errors, like 'Invalid drive specification', but I don't know where that is coming from.
Answer
RMagic won't work with ImageMagic 6.8. I updated the RMagick Github wiki with detailed instructions.
https://github.com/rmagick/rmagick/wiki
There I found gems (haha) such as
If ImageMagick isn't first in your system path, you'll get an "Invalid drive specification" error when extconf.rb tries to identify the ImageMagick version.
and
gem install rmagick -- '--with-opt-dir="[path to ImageMagick]"'
(Obvious, huh?)
I believe RMagick is a dead project. There hasn't been a commit for 2 years!
