Installing rmagick on ubuntu 10.04

Tags: ruby, ubuntu

I just installed ruby and rmagick on an ubuntu 10.4 server. Got some errors during the installation and thought i should summarize the procedure here:

Install ruby

sudo apt-get install ruby1.9.1 rubygems1.9.1

Install imagemagick

sudo apt-get install imagemagick

Tried to install rmagick

sudo gem install rmagick

Got this error:

ERROR:  Error installing rmagick:
	ERROR: Failed to build gem native extension.
 
/usr/bin/ruby1.9.1 extconf.rb
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
	from extconf.rb:1:in `<main>'
</main>

Found this page, which pointed med to install ruby1.9.1-dev package.

sudo apt-get install ruby1.9.1-dev

Ok, trying again to install rmagick

sudo gem install rmagick

Got this error:

ERROR:  Error installing rmagick:
	ERROR: Failed to build gem native extension.
 
/usr/bin/ruby1.9.1 extconf.rb

Can't install RMagick 2.13.1. Can't find Magick-config in /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin
 
*** extconf.rb failed ***
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.

Found this question on superuser.com which pointed me to install the libmagickwand-dev-package.

sudo apt-get install libmagickwand-dev

Finally, another attempt to install rmagick

sudo gem install rmagick

Building native extensions.  This could take a while...
