|Installing RMagick on Linux, *BSD, or Cygwin systems|
This page describes a method for installing RMagick, ImageMagick or GraphicsMagick, and the delegate libraries used by ImageMagick and GraphicsMagick. You only need to install one of ImageMagick or GraphicsMagick. The procedure is the same for either library. Throughout the remainder of this document I will use the word ×Magick to refer to either of these two libraries. I developed this procedure using Mandrake Linux. If you are using FreeBSD or a different Linux distro some of the details may be different. In particular these instructions assume you are using bash as your shell.
You will need to have a connection to the Internet and around an hour of free time (assuming you have a broadband connection).
Depending on how you originally set up your system you may already have these tools. If not, you'll need to install
Generally each system has these tools available as pre-built packages. Consult your system documentation for more information.
I recommend these delegate libraries:
You may also want to install some of the other delegate libraries listed in the FAQ. Your distribution may include at least some of these libraries by default and probably provides pre-built packages for the others. If not, the delegates are available as source code tarballs from http://www.imagemagick.org/pub/delegates/.
Go to http://www.imagemagick.org or http://www.graphicsmagick.org (if you install GraphicsMagick you must install RMagick 1.15.nn) and download the latest version of the software to a temporary directory. Unroll the tarball and make the top directory current. For example, if you downloaded the ImageMagick.tar.gz file, use these commands (where X.Y.Z is the ImageMagick version number):
tar xvzf ImageMagick.tar.gz cd ImageMagick-X.Y.Z
Similarly, if you downloaded the GraphicsMagick-LATEST.tar.gz file, use these commands (where X.Y.Z is the GraphicsMagick version number):
tar xvzf GraphicsMagick-LATEST.tar.gz cd GraphicsMagick-X.Y.Z
The same command can be used to configure either ImageMagick or GraphicsMagick:
./configure --disable-static --with-modules --without-perl \ --without-magick-plus-plus --with-quantum-depth=8
./configure command should be entered on a
single line. This installs ×Magick in /usr/local. If you
want to install into another directory use the --prefix
configure command should be entered on a
single line. Here's what the options do:
--with-modulescause ImageMagick/GraphicsMagick to be built with dynamically loaded modules.
--without-magick-plus-plusto suppress installing Perl and C++ support.
--with-quantum-depth=8configures ImageMagick to use a bit depth of 8. The default quantum depth for ImageMagick is 16. See Speed up your RMagick apps in 1 easy step in the RMagick Hints & Tips Forum for a discussion why you should use this option.
Finally, if you have the standard Microsoft Windows fonts on
your system (as is frequently the case when dual-booting), add
the --with-windows-font-dir option to tell ×Magick where to
find them. For example, suppose you have the Windows fonts in the
For more information about all these options see ImageMagick/GraphicsMagick's README.txt file.
There are many more options. For more information about all these options see ×Magick's README.txt file.
./configure will produce quite a bit of output.
The last page is the most interesting. If you've successfully
performed all the steps so far and used all the defaults, the
output from configure should end with a page similar to this. (Of
course some of the details will be different depending on your
ImageMagick is configured as follows. Please verify that this configuration matches your expectations.

Of course, instead of VERSION X.Y.Z you will see the version number of the version of ×Magick that you downloaded. Check your output to make sure that ×Magick located all the delegate libraries. You should see "yes" in the Value column for FreeType 2.0, JPEG v1, PNG, WMF, X11, as well as for any other delegate libraries you chose to install.

resolve those issues before continuing. Re-run
./configure, being very careful to enter the
Once you're satisfied that you've configured ×Magick the way you want it, enter these two commands:
make sudo make install

The hard part is done. All we have to do now is install RMagick. Here you have two choices.
Installing the gem takes only one command, but you must first install RubyGems and if something goes wrong it's harder to figure it out. Installing from the source tarball produces better diagnostic output, which is useful if you run into trouble.
Issue the command
sudo gem install rmagick
If you installed GraphicsMagick in step 2 then you must install the latest RMagick 1.15.nn gem using the gem command's -v option, like this. Use the latest fix number instead of nn.
sudo gem install rmagick -v 1.15.nn
You'll see this output:
Bulk updating Gem source index for: http://gems.rubyforge.org Building native extensions. This could take a while... Successfully installed rmagick-X.Y.Z
Be patient. A lot of time will pass with no output from the
gem command. The "Successfully installed" message does not mean
that RMagick was successfully installed. The RMagick installation
can encounter error conditions that
detect. The following irb session is a better indicator of a
successful install. (Of course the version numbers in the message
may vary from what is shown here, depending on what versions of
the software are currently available.)

If you haven't already done so, download the RMagick tarball from RubyForge (if you installed GraphicsMagick in step 2 then you must download RMagick 1.15.nn) and unroll it into a temporary directory. Make that directory current.
tar xvzf RMagick-X.Y.Z.tar.gz cd RMagick-X.Y.Z
There is no need to use
--prefix. RMagick will be
installed in the appropriate directory in Ruby's search path.
The configure script accepts some
RMagick-specific options for special conditions. Enter
./configure --help for more information.
The make step will take a few minutes to run since it builds all of the RMagick examples. You should get no error messages. If something is wrong with the way ImageMagick/GraphicsMagick was configured and more than 5 examples fail, you'll get an error message here. Fix the problem(s) and re-install ImageMagick/GraphicsMagick.
sudo make install

That's it. You should have a complete install of ImageMagick/GraphicsMagick and RMagick.
