  Mac OS X & Rails & ImageMagick without the kruft
Recently I got one of the new Intel iMacs, and I wanted to move all my Rails development over to it. Most things went very easily, however ImageMagick doesn't seem to have a binary for Intel Macs just yet. I decided to try and install it from source. It was actually very easy to do. So if you don't feel like installing Darwin Ports/Fink just to get ImageMagick read on.

If you're not comfortable dealing with the Terminal/shell access then you may want to wait for the binary release, or go the Darwin Ports/Fink route.

Ideally you should have followed the Rails installation tutorial at Hivelogic.

Basically you need to have your path setup to look in /usr/local/bin for binaries. If you need help doing that, have a look at the aforementioned article.

Start up Terminal(usually located in the /Applications folder).

At the prompt enter:

mkdir src
cd src

Now we're ready to get and install the required software.

Note: the order here is important.


This supports PNG files. If you don't need support you can safely skip it.

curl -O
tar zxvf libpng-1.2.8-config.tar.gz
cd libpng-1.2.8-config
./configure --prefix=/usr/local
sudo make install



Pretty much everyone needs this. Unfortunately it's the most troublesome to compile and
install correctly. Follow the directions carefully. Note: The single quotes in the fourth line
are backquotes, not regular quotes. (see the tilda key)

curl -O
tar zxvf jpegsrc.v6b.tar.gz
cd jpeg-6b
ln -s `which glibtool` ./libtool
./configure --enable-shared --prefix=/usr/local
sudo make install


Everyone needs this as well.

curl -O
tar zxvf tiff-3.8.2.tar.gz
cd tiff-3.8.2
./configure --prefix=/usr/local
sudo make install


The big tamale! The [VERSION] tag below denotes the version of ImageMagick you actually got. ImageMagick.tar.gz is a link to the latest version of ImageMagick, so the version will change as they do new releases.

curl -O
tar zxvf ImageMagick.tar.gz
cd ImageMagick-[VERSION]
./configure --without-perl
sudo make install

Updated to use the latest version via the linked file.


One more step, add the ruby bindings to ImageMagick. You may get some errors during the Rdoc
install phase, you can safely ignore them.

sudo gem install rmagick

Woot! You're done. Have a beverage, and get down to work.
