Installation of ImageMagick¶

Download last setup package from http://www.imagemagick.org/script/binary-releases.php#windows and run it.

Installation of the rmagick gem¶

• open a new command prompt
• set CPATH and LIBRARY_PATH environment variables to point respectively to ImageMagick installation directory include and lib subdirectories (so the DevKit will find them at build time)

For example:

set CPATH=C:\Program Files\ImageMagick-6.7.7-Q16\include
set LIBRARY_PATH=C:\Program Files\ImageMagick-6.7.7-Q16\lib

• actually install the gem, e.g. with gem install rmagick or bundle install --without=development test, etc.
