Ruby, Windows and RMagick

Been doing a lot of rails work on windows recently and ran into some issues that needed solved.  Just like on Unix, to get the RMagick gem working on a windows platform you need to install ImageMagick.  Go to and download

Double click and go through the installer, selecting to install C and C++ header files and libraries from the additional options page (this is very important)

Then add environmant variable CPATH=\path\to\imagemagick\include and LIBRARY_PATH=\path\to\imagemagick\lib

You can then ‘gem install rmagick’ and it will build it using the native image magick libraries.
