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.

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!
