To launch any Scol application, Scol must be already installed. To run an application, launch it must be sufficient (Scol will be called automatically). Sometimes, it need to launch Scol before.

How to run Scol on a MS Windows system ?¶

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).

How to run Scol on a GNU/Linux system¶

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

1. Log in with the same user (see How to install Scol)
2. Go to in Scol install directory
3. Run Scol :
   $ ./scol &
4. 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 :

1. execution rights ?
2. edit this script (with vi, emacs, nano, ...) and replace
   SCOLPATH=$HOME/.../scol
   by
   SCOLPATH=/home/my_login/.../scol

Create a launcher¶

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

#!/usr/bin/env bash
cd $HOME"/Bureau/scol/scol/" 
./scol &

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

#!/usr/bin/env bash
cd $HOME"/Bureau/scol/scol/" 
./scol ./partition/tutoriels/codes/8/launchSRV.scol

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, ...).

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).

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 ".

General¶

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

SO3Engine¶

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.

Legacy 3d engine¶

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.

Webcam¶

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.

Network¶

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.

Maintenance¶

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 !).

Old versions¶

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