Hey everyone,
Just curious if anyone has had any luck installing ImageMagick-6.7.4-Q16
and rmagick-2.13.x. I have been trying to follow a few posts out here, but
no luck. I can obviously get ImageMagick in stalled, but when I try to
install the gem rmagick(gem install rmagick) It’s like it’s trying to build
the gem.
TL;DR : $ sudo apt-get install libmagickcore-dev libmagickwand-dev

Yes, it is trying to build “native extensions”.
Assuming you saw this error:
~/data/projects/temp/rmagick$ bundle install

Installing rmagick (2.13.1) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:

Gem files will remain installed in

inspection.
Results logged to /home/peterv/.rvm/gems/ruby-1.9.3-p0@rmagick
/gems/rmagick-2.13.1/ext/RMagick/gem_make.out
An error occured while installing rmagick (2.13.1), and Bundler cannot
continue.
Make sure that gem install rmagick -v '2.13.1'
succeeds before
bundling.
I used the regular trick to find the required debian/Ubuntu packages:
~/data/projects/temp/rmagick$ apt-cache search magick | grep ‘-dev’
libmagick+±dev - object-oriented C++ interface to ImageMagick -
development files
libmagickcore-dev - low-level image manipulation library - development
files
libmagickwand-dev - image manipulation library - development files
graphicsmagick-libmagick-dev-compat - image processing libraries
providing
ImageMagick interface
libgraphicsmagick++1-dev - format-independent image processing - C++
development files
libgraphicsmagick1-dev - format-independent image processing - C
development files
libvips-dev - image processing system good for very large images (dev)
Installed
~/data/projects/temp/rmagick$ sudo apt-get install libmagickcore-dev
this pulls in 80+ packages … probably a smaller set would suffice …
~/data/projects/temp/rmagick$ sudo apt-get install libmagickwand-dev
this was only 1 package
And now gem install or bundle install works:
~/data/projects/temp/rmagick$ bundle install
Fetching source index for http://rubygems.org/
