Can anyone tell this noob what I’ve done wrong? I tried to install
rmagick,
but apparently it fails.

C:\InstantRails\rails_apps>gem install rmagick -r

To install RMagick on Windows, use the rmagick-win32 gem. See
http://rmagick.rubyforge.org/install-faq.html.

OK thanks, however, I’m a little confused. I used gem install -r
command to
install ajax_scaffold. Is the procedure for installing rmagick
different
because it’s bundled with other things…like ImageMagick?

Just curious.
Thanks.

Partly. The “rmagick” gem includes the source code for RMagick. It
configures itself to the version of ImageMagick that is installed on the
system and then compiles RMagick for that version. The “rmagick-win32”
gem is pre-compiled and is configured for use the specific version of
ImageMagick it is bundled with.
