Fedora, Centos, Scientific Linux

To facilitate the installation on RPM based Linux distributions, the package includes a spec file which can be used to produce RPM packages for linux distributions that support them (Fedora, Red Hat etc). The developers have built 64-bit RPM packages of GtkExtra-3 for the Fedora and Redhat EL/CentOS/Scientific Linux distributions. These can be downloaded from the RPM repository that is hosted by the X-ray Microspectroscopy and Imaging research group of Ghent University.


Access to this repository can be obtained as follows for Fedora 20,21,22 distros:


su -c ‘rpm -Uvh'


for Red Hat EL 6 based distributions:


su -c ‘rpm -Uvh'


and for Red Hat EL 7 based distributions:


su -c ‘rpm -Uvh'


After that, the GtkExtra-3 packages themselves can then be downloaded using yum:


su -c 'yum install gtkextra3 gtkextra3-devel'


Updates can be installed in a similar way:


su -c 'yum update gtkextra3 gtkextra3-devel'



Packages were created for Debian and Ubuntu. In order to access these packages using your favorite package manager, execute the following command to import our public key:


curl | sudo apt-key add -


Next, add the package download location corresponding to your distribution to the /etc/apt/sources.list file (as root):


Ubuntu Vivid 15.04:

deb [arch=amd64] vivid stable
deb-src vivid stable


Ubuntu Utopic 14.10:

deb [arch=amd64] utopic stable
deb-src utopic stable


Ubuntu Trusty 14.04:

deb [arch=amd64] trusty stable
deb-src trusty stable


Ubuntu Precise 12.04:


deb [arch=amd64] precise stable

deb-src precise stable



Debian Jessie:


deb jessie stable

deb-src jessie stable


Debian Squeeze:


deb squeeze stable

deb-src squeeze stable


Debian Wheezy:

deb wheezy stable
deb-src wheezy stable


When the sources.list file contains the correct download locations, update the apt cache by running:


sudo apt-get update

After this, one can install GtkExtra-3 by executing the following command:


sudo apt-get install libgtkextra3 libgtkextra3-dev
