Error installing Rmagick on Mac OS X

Question

I followed the installation of RMagick for OSX: http://rmagick.rubyforge.org/install-faq.html#osx

I have done the Imagemagick installation from John Maddux (solution to install ImageMagick on OSX without using MacPorts)

Here's my terminal window:

Suebphatt:~ suebphattleelertphong$ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]

Suebphatt:~ suebphattleelertphong$ rails -v
Rails 3.0.3

Suebphatt:~ suebphattleelertphong$ gem -v
1.3.7

Suebphatt:~ suebphattleelertphong$ gem install rmagick
Building native extensions.  This could take a while...

Thanks a lot for help, Suebphatt

I would strongly recommend you try homebrew, which is a great replacement for macports:

Once you get homebrew installed, you should be able to install imagemagick and rmagick very easily:

brew install imagemagick     # will take a while!
gem install rmagick

UPDATE: (thanks to JJD and this answer)

Try to install without openpmp if you are having trouble with a chiliproject install:

brew install imagemagick --disable-openmp

UPDATE X2: (thanks to Ramon Araujo's comment)

If you have previously installed imagemagick with homebrew, you will have to unlink it before you install again:

brew unlink imagemagick

Hi, bowsersenior, Thank you for the suggestion. I'll try it and will let you know the result. – howdy Nov 27 '10 at 11:55
I tried to install [chiliproject](https://www.chiliproject.org) and successfully followed this advise to [install imagemagick without openmp](http://stackoverflow.com/a/7973760/356895). – JJD May 21 '12 at 12:23
@JJD Thanks for the comment. I've updated my answer with your info. – bowsersenior May 27 '12 at 18:12

Perfect, just one comment. I had imagemagick already installed using brew, so it asked me first to 'brew unlink imagemagick' before. After I did that, then I followed again your suggestions and it all went perfect! Thanks @bowsersenior. – Ramon Araujo Oct 26 '12 at 05:31
Thanks @RamonAraujo, I have updated my answer with that info. – bowsersenior Oct 26 '12 at 23:28
Updated my answer to include link to `brew.sh` – bowsersenior Jun 29 '13 at 03:16

Another think to watch out is the version of imagemagick. I had ImageMagick version 6.8.0, which is the latest if you install from homebrew, and rmagick just does not compile with this version. So do a

convert --version

and make sure that your ImageMagick is 6.7 or less otherwise rmagick wont compile..

And to install a specific version (using homebrew)... https://coderwall.com/p/lqphzg – David Vezzani Jan 21 '13 at 20:41

Struggled with this problem for a while, and the fix below (copied from this SO answer solved the issue (specifically the section about symbolic links).

rmagick has a problem working with imagemagick (>= 6.8.0-10) from homebrew.

You can either

update rmagick gem by

bundle update rmagick

or manually symbol link some dylib to make it work:

$ cd "`Magick-config --prefix`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

After that gem install rmagick should work.
