How to build ImageMagick and install RMagick with MacPorts on Mac OS X Leopard

Oh holy day, brand new operating system for me to poke my grubby little fingers at!

Leopard is a piece of work that is for sure, but for some of us getting back to the bliss that was the Rails development environment on Tiger will take a little doing. In today’s journey will get RMagick running again.

Apple has provided us with a near complete rails environment out of the box, but there are two big missing pieces: the mysql gem, and rmagick.

Normally, we would simply install rmagick with:

sudo port install ImageMagick
sudo gem install rmagick

But it turns out the tiff port in macports fails to build when using apples new implementation of opengl in leopard. so:

Getting RMagick, Leopard-Style

sudo port install tiff -macosx  #disables the linkage with Apple's open gl
sudo port install ImageMagick
sudo gem install rmagick

Simple as that.

    Thanks! That's just what I was looking into. It's great to see how issues are found and solved by the community.

  2. Jordi Says:

    But is that using Apple's ruby and rubygems, or MacPorts? I figured out the -macosx part, but my gem won't build. Bitching about missing freetype, which is installed.

    Which ruby were you using?

  3. Jordi Says:

    Nevermind. I did sudo port install ImageMagick +no_x11, which means I had to do sudo port install ghostscript as well before installing the gem. Problem solved!

    I'm running into an issue when trying to install ImageMagick. I get the following error:

    sudo port install ImageMagick Error: Unable to execute port: invalid command name "destroot.violate_mtree"

    Any idea what's going on?


  6. Greg Says:

    BryanD…. Do sudo port selfupdate to get 1.5.2 which will fix that issue.

    Just a heads-up… After solving the GCC issues by installing Xcode 3.0, I had some other issues getting this installed due to a missing GNUTAR in /usr/bin. For some reason, it was not existent on my factory Leopard install. I can't be sure that it wasn't there and somehow removed, but copying getting a copy of TAR from a Tiger install and dropping it into /usr/bin did the trick. Also, be sure to symlink tar to gnutar (ln -s /usr/bin/tar /usr/bin/gnutar), as MacPorts looks for /usr/bin/gnutar
