Click on the _Start men_u, choose _Programs_ and _Scol Voyager_. The Scol icon (bluish) will display in the tasks bar (next to the clock). Click right on the icon top open a contextual menu.

You can launch the application from the file explorer : go to its directory and double-click on the *.scol file. Some Scol applications can be in the _Start Menu_ (depending on the installation way).

h2. How to run Scol on a GNU/Linux system

The version is not up to date and it need the terminal yet.

# Log in with the same user (see [[How to install Scol]])

# Go to in Scol install directory

# Run Scol :

    @$ ./scol &@

# If you want launch an application :

    @$ ./scol relative_path_to_the_application/script_file.scol@

If an error occurs, check the executable script named scol in the install directory :

# execution rights ?

# edit this script (with vi, emacs, nano, ...) and replace 

@SCOLPATH=$HOME/.../scol@ 

by 

@SCOLPATH=/home/my_login/.../scol@

h3. Create a launcher

Create a blank file anywhere (but accessible by this user). Add these lines (improve according to your needs) :

<pre>

#!/usr/bin/env bash

cd $HOME"/Bureau/scol/scol/"

./scol &

</pre>

Save it. Create a second blank file (one per application) and add theses lines :

<pre>

#!/usr/bin/env bash

cd $HOME"/Bureau/scol/scol/"

./scol ./partition/tutoriels/codes/8/launchSRV.scol

</pre>

Don't forget to give the execution rights at these two file :

@

$ chmod -x your_file@

To launch Scol, call the first script. To run an application, call the first script, next, call the second.

To have a graphical launcher, read the documentation of your desktop environment (GNOME, KDE, XFCE, ...).

This small tool in Python can help you : "ScolLinux":http://iri3d.free.fr/OUTILS/Scollinux [Fr].

h2. How to configure Scol ?

Here is the configuration for version 6.x.

You should configure Scol to optimize these performances on your system and to custom its behavior.

The Scol voyager (or Voyager) is the interface between the user and the operating system. This has a graphical interface to configure the Scol behavior and launch any Scol applications.

The Voyager can be partially removed and a product can be published like this (for experts only).

!http://www.irizone.net/scolring2/images/scol/voy_popup.png! Launch Scol and click right on the Scol icon (in the tasks bar) to display a contextual menu.

By default, the Scol is inactive except if a Scol application is running or if you launch Scol explicitly. This decreases the resources consumed by your computer.

Once Scol is started, click on the Scol icon with the right mouse button. In the displayed contextual menu (pic. above), select " _Settings_ ".

h3. General

!http://www.irizone.net/scolring2/images/scol/voyager5x_conf_gen.jpg! 

Select your favorite language and your pseudonym : the Voyager and some applications use these parameters when they launch themselves.

h3. SO3Engine

!http://www.irizone.net/scolring2/images/scol/voyager5x_conf_so3e.jpg! 

In " _SO3Engine settings_ ", you can configure the new 3d engine : OpenGL (better often) or DirectX renderer, etc. In an application, if the 3d crashes or the rendering is bad, you could change these settings.

h3. Legacy 3d engine

!http://www.irizone.net/scolring2/images/scol/voyager5x_conf_old3d.jpg! 

In the " _Old engine_ " (legacy 3d engine), select the best values according to the capacities of your system (a high number implies more resources). This is not applied in the recent softwares.

h3. Webcam

!http://www.irizone.net/scolring2/images/scol/voyager5x_conf_wcam.jpg! 

In " _Webcam_ " sub item : If you have a webcam, connect it and select the driver in the combo list. Check the image, if nothing, select another driver.

h3. Network

!http://www.irizone.net/scolring2/images/scol/voyager5x_conf_net.jpg! 

For the " _Network_ " settings : choose your external IP address. If you use a proxy, configure it : the "automatic setup" check box should be sufficient. Otherwise, you should set manuelly.

h3. Maintenance

!http://www.irizone.net/scolring2/images/scol/voyager5x_conf_misc.jpg! 

In " _Maintenance_ ", you can enable/disable write log files (helpful to debug Scol or an application).

The "developer mode" disable the closing Scol when no application is running. This is useful fora  coding.

The send of "statistics" is optional : Scol version, number of connections, date of the last connection and IP address. Only the development team has access to these data.

It is recommended to keep the "update" box checked to have Scol up to date.

The "Clear cache" button : remove all files in the Scol cache. Sometimes, a bad cache may make an application unstable ; clear the cache can resolve that.

The "Clear logs" button : remove all log files to increase the free disk space for example (if logs have been enabled !).

h2. Old versions

To configure a previous version of Scol, see [[How to configure a version 5.x]].
