Install GraphicsMagick on AWS EC2 running Ubuntu Linux

guide.md

I use GM to render thumbnails of png and jpg images.

Sadly the GM installation guide doesn't describe how to get things working on AWS EC2.

Prepare for installing GraphicsMagick

PROMPT> sudo apt-get update
PROMPT> sudo apt-get install libpng12-0
PROMPT> sudo apt-get install libjpeg-dev
PROMPT> sudo apt-get install ghostscript
PROMPT> sudo apt-get install libtiff5-dev
PROMPT> sudo apt-get install libfreetype6
PROMPT> sudo apt-get install libfreetype6-dev

Download GraphicsMagick's source code (9 MB). This takes about 10 minutes

PROMPT> wget ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/1.3/GraphicsMagick-1.3.26.tar.gz

Unzip and configure GraphicsMagick

PROMPT> tar xzvf GraphicsMagick-1.3.26.tar.gz
PROMPT> cd GraphicsMagick-1.3.26
PROMPT> ./configure

Check that the result of configure looks like this

It must have png and jpg support, otherwise GraphicsMagick won't be to much help making thumbnails.

GraphicsMagick is configured as follows. Please verify that this
configuration matches your expectations.
