CentOS 5.5

libvips

Note: The biggest problem of installing latest vips on CentOS5 is that it depends on glib2 of much higher versions than available in CentOS5 repo. Recently John added support for CentOS5 - he took off libvips dependency on higher versions of glib2 - now libvips can be installed without need to upgrade glib2, using just repo's 2.12.3 version.

If you are trying to compile <7.28.8 version, you additionally need to upgrade glib2 to this version - 2.21.6 - I couldn't manage to compile libvips using following glib versions: 2.16, 2.17, 2.32, I advice you version that worked for me (see compilation steps right below)

# For libvips < 7.28.8
wget http://ftp.acc.umu.se/pub/gnome/sources/glib/2.21/glib-2.21.6.tar.gz
tar zxvf glib-2.21.6.tar.gz
cd glib-2.21.6/
./configure
make
make install

And finally

wget -c http://www.vips.ecs.soton.ac.uk/supported/current/vips-7.28.8.tar.gz
tar xzvf vips-7.28.8.tar.gz
cd vips-7.28.8
./configure && make && make install

ruby-vips gem

gem install ruby-vips

Possible problems

Following EXPORT is needed if you will have problems like described here: https://github.com/jcupitt/libvips/issues/20

# https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=VIPSIP;db1e4401.0706
# To run 'gem install vips' once
$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig
# or for constant use
$ echo "export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig" >> ~/.bash_profile

If you will see:

1.9.3-p194 :001 > require 'vips'
LoadError: libvips.so.32: cannot open shared object file: No such file or directory

Do this:

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

Gentoo

If you are trying to compile the latest vips source from official site, see "Possible problems" section from instructions for CentOS 5.5.
