Problem installing RMagick rubygem on Centos 5

Question

I\'m having problems installing the RMagick rubygem on Centos 5. I\'ve followed the steps detailed in http://rmagick.rubyforge.org/install2-linux.html but when I try:

Answer 1

Centos 5.5 the ImageMagick is legacy, so install from source to can use the rmagick.

Get the source RPM

wget ftp://ftp.kddlabs.co.jp/graphics/ImageMagick/linux/SRPMS/ImageMagick.src.rpm
rpm -ivh --nomd5 ImageMagick.src.rpm
cd /usr/src/redhat/SPECS
rpmbuild -ba ImageMagick.spec

Probably you get dependence error for:

• perl-devel
• jasper-devel
• djvulibre-devel

Add to your /etc/yum.repos.d/dag.repo

[dag]
name=Dag RPM Repository for CentOS5
baseurl=http://ftp.riken.jp/Linux/dag/redhat/el5/en/$basearch/dag/
enabled=0
gpgcheck=1

Then import the GPG key and install the djvulibre-devel

rpm --import http://ftp.riken.jp/Linux/dag/RPM-GPG-KEY.dag.txt
yum --enablerepo=dag install djvulibre-devel

Then check if you can make the RPM:

rpmbuild -ba ImageMagick.spec

If you get the perl-devel dependency error.

yum install perl

Then edit the ImageMagick.spec and replace "perl-devel" for "perl", save and rpmbuild again.

rpmbuild -ba ImageMagick.spec

So install the the other dependences:

yum install freetype
yum install gd-devel
wget http://www.osresources.com/files/centos-windows-fonts/msfonts.tbz
mkdir /usr/share/fonts/default/TrueType
tar xvjpf msfonts.tbz -C /usr/share/fonts/default/TrueType/

Let's install it:

cd /usr/src/redhat/RPMS/i386
rpm -Uvh ImageMagick-*

After all you can test if your RMagick is installed:

ruby -rrubygems -e "require 'RMagick'; puts Magick::Long_version;"

Answer 2

So I've finally managed to install version 1.15.17 of the rmagick rubygem! Here's what I did:

1. Uninstalled ImageMagick 6.5.4-9 and the delegate libraries that I had installed from source
2. sudo yum install ImageMagick
3. sudo yum install ImageMagick-devel
4. curl -O http://www.zacharywhitley.com/linux/rpms/fedora/core/6/i386/msttcorefonts-2.0-1.noarch.rpm
5. sudo rpm -ivh msttcorefonts-2.0-1.noarch.rpm
6. ln -s /usr/share/fonts/msttcorefonts/ /usr/share/fonts/default/TrueType
7. sudo gem install rmagick -v 1.15.17 --no-rdoc --no-ri

Blog entries from David Bock and Will were invaluable.

Answer 3

The answer from rubiojr worked for me, but the rbel.co is down at the moment. You can use rbel.frameos.org instead:

rpm -Uvh http://rbel.frameos.org/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel
gem install rmagick

Answer 4

I got around this in RHEL 5.4 by temporarily symlinking /usr/local/bin/Magick-config to /usr/bin/Magick-conf, so the gem install could find this Magick-config executable.

In my case, I installed ImageMagick from source with --prefix=/usr/local. For some reason, the gem install didn't want to look there for the config, even with gem install --local ../rmagick-2.12.2.gem -- -with-opt-dir=/usr/local/bin. Running yum install ImageMagick-devel would get the binary there, but then the gem install would say that ImageMagick was the wrong version.

Answer 5

kept getting this error after following the instructions in the most voted answer:

RMagick: unable to read font `(null)'.

so I have something to add to step 7, taken from an update to David Bock's blog:

http://blog.codesherpas.com/on_the_path/2009/09/installing-centos-5-imagemagick-and-rmagick-september-2009-edition.html

gem install rmagick -v 1.15.17 --no-rdoc --no-ri -- --disable-htmldoc

disabling html-documentation is crucial for avoiding further errors if your font files make rmagick unhappy. Just the outcome of about 2 hours of struggling with this issue.

Answer 6

I've recently backported ImageMagick 6.5.4.7 from CentOS6 to CentOS5 so installing rmagick should be easier right now:

rpm -Uvh http://rbel.co/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel
gem install rmagick
