Let's install GraphicsMagick!

cd /usr/local/src
wget ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/GraphicsMagick-LATEST.tar.gz
tar xvfz GraphicsMagick-LATEST
cd GraphicsMagick-*
./configure --enable-shared
make
make install

Let's test it.

gm version 

If you get this error:

gm: error while loading shared libraries: libGraphicsMagick.so.3: cannot open shared object file: No such file or directory

 Do this to fix:

echo "/usr/local/lib" >> /etc/ld.so.conf
ldconfig

Ok... Let's install GMagick PHP extension

Go into /usr/local/src directory

cd /usr/local/src

First, we need to get all the required libraries...

yum search ImageMagick-devel
