Getting the rmagick 2.12.2 gem working on Mac OS X

So getting rmagick 2.12.2 working on Mac OS X isn’t the easiest thing in the world, but it is possible.

The first thing I should say is that this assumes you already have ImageMagick installed on your machine, the second thing is that there is a rmagick 2.13.2 gem, which seems to work out of the box.

In my case I couldn’t use 2.13.2 so I had to get things working with 2.12.2.

If you Google this issue there are loads of solutions out there, unfortunately all the low-hanging fruit didn’t work for me, these are things like;

• Making sure ImageMagick is installed
• Telling the ruby gem where ImageMagick lives with -- --with-opt-dir

Thanks to gist I was able to get it sorted.

Here is a dump of the fix that you type into the terminal;

cd /usr/local/Cellar/imagemagick/6.8.0-10/lib
ln -s libMagick++-Q16.7.dylib   libMagick++.dylib
ln -s libMagickCore-Q16.7.dylib libMagickCore.dylib
ln -s libMagickWand-Q16.7.dylib libMagickWand.dylib
