After a lot of time triying, i could finally install rmagick-2.12.2 gem
in ruby-1.8.7 on Windows-Xp.
If ImageMagic is installed in c:/ImageMagic, the secret to install the
gem is the --with-opt-dir:
gem install rmagick -v=2.12.2 – --with-opt-dir=c:/imagemagick --remote
I have also tried to install magickwand with the same method , but don’t
