Switched to the {{relax source}} template for repository links, and removed all SVN references.
__TOC__
== Installing the relax dependencies ==
The python-devel and scons packages are only required if the C modules need to be compiled for your system. <br>
* [http://plasma-gate.weizmann.ac.il/Grace/ Grace] software is used for visualisation of 2D data sets.
* '''subversion''' is only if you wan't to checkout the source code.
* matplotlib is not a necessity, but is likely to be implemented later for extended plotting.
=== RHEL 5 and compatible distributions ===
For RPM-based Linux distributions with access to the YUM installer, first install the relax dependencies with:
<source lang="bash">
yum install python
yum install python-devel
yum install numpy
yum install scipy
yum install scons
yum install wxPython
yum install grace
yum install subversion
yum install python-matplotlib
# We can manage python package installations with pip
sudo easy_install pip
</source>
If you do not have root access but are in the '''sudo ''' group, you can type:then add a '''sudo''' before each of the above commands.<source lang== Minfx and Bmrblib =="bash">sudo yum install pythonsudo yum install scons# [[Minfx#Install | Minfx]]sudo yum install wxPythonsudo yum install grace# [[Bmrblib#Install | Bmrblib]]</source># [[mpi4py#Install | mpi4py]]

This is done using the scons program, by simply typing:
<source lang="bash">
scons
</source>
You must be in the base relax directory for this to work.
In addition, if you would like to compile the relax user manual via LaTeX, you can also use scons. See the wiki page [[manual]].:
=== Add to path - C_shell / Tcsh ===

Restart the terminal, to load the new variables.

== Trouble shooting ==
=== The menu icons are missing in Linux. ===
On some Linux systems, the icons for the menu items are not shown. This was a decision taken by the Gnome developers at some point to keep the GUI minimal, though in recent versions this behaviour has been reverted. <br>
If you suffer from this problem, to reactive the icons simply type in the shell:
gconftool-2 --get /desktop/gnome/interface/menus_have_icons
gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true
For GNOME 3
# Get schemas
gsettings list-schemas
gsettings list-schemas | grep org.gnome.desktop
gsettings list-schemas | grep org.gnome.desktop.interface
# Get keys
gsettings list-keys org.gnome.desktop.interface
gsettings list-keys org.gnome.desktop.interface | grep icon
gsettings list-keys org.gnome.desktop.interface | grep desktop
# Get value
gsettings get org.gnome.desktop.interface icon-theme
# https://wiki.archlinux.org/index.php/GNOME/Tips_and_tricks#Enable_button_and_menu_icons
# Since GTK+ 3.10, the GSettings key 'menus-have-icons' has been deprecated. Icons in buttons and menus can still be enabled by setting the following overrides:
gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1>}"
# Check
gsettings list-keys org.gnome.settings-daemon.plugins.xsettings
gsettings get org.gnome.settings-daemon.plugins.xsettings overrides
