Starting from version 3.0 the source code of GDToolkit is no longer freely distributed. The following packages, precompiled for all the supported platforms, are available free of charge for academic research and teaching purposes only: To all the above packages a limitation on the number of the vertices applies, so that you are not allowed to draw graphs with more than twenty vertices.

As a user of GDT you need a licence. The research-and-teaching license for the packages above mentioned is automatically sent to you with the packages themselves by the DIA - Dipartimento di Informatica e Automazione, Università di Roma Tre, Rome, ITALY. Any use of GDT by a company, government institution or other non-academic organizations is considered to be commercial use and is NOT allowed. Commercial users have to purchase a commercial license from INTEGRA Sistemi S.r.l. (Italy). Please contact Antonio Leonforte.

In order to keep track of the GDT research installations, we need some basic information including your name, your organization, your job and the objective for which you want to use GDT. You can simply provide such information by filling and submitting the GDToolkit download form.

When the submitted form contains all the required information, an e-mail is automatically sent to you, containing your research version license and, in attachment, the requested package.

How to get, install and test the software
1 Verify the following preconditions:
  • Your platform is supported by the current version of GDT.
  • A compatible release of LEDA is currently installed on your system.
  • You have at least 30Mb available on your hard disk.

If you don't have a compatible LEDA version installed on your system, you can download LEDA (free of charge for academic research and teaching) from the Max Plank Institute. LEDA-R is Copyright (c) 1991-1999 by Max-Planck-Institut fuer Informatik Im Stadtwald, 66123 Saarbruecken, Germany. All rights reserved.
NOTE: If you are downloading LEDA 4.1, make sure you download the package LEDA-4.1-win32-msc60-lib-ml.exe (if you mean to use it with MSVC++ 6.0), or LEDA-4.1-i386-linux-eg++-1.1.tar.gz (if you mean to use it with Linux), or LEDA-4.1-sparc-solaris-eg++-1.1.tar.gz (for the Solaris platform).

2 Fill in and submit the GDToolkit download form. After one or two minutes (the package is built on the fly) an acknowledgment html page appears on your browser, and, at the same moment, a mail is sent to you with the package in attachment. You may press the back button twice on your browser to get back to this page.
3 Move the downloaded archive file into a directory on which you have write permission.
4 Uncompress the archive preserving the paths of the contained files. On a linux platform, for example, you may download GDT-3.0-LEDA-4.1-i386-linuxRedHat5.2-egcs.tgz and issue first the command "gunzip GDT-3.0-LEDA-4.1-i386-linuxRedHat5.2-egcs.tgz" in order to get a GDT-3.0-LEDA-4.1-i386-linuxRedHat5.2-egcs.tar file, and then issue the command "tar xvf GDT-3.0-LEDA-4.1-i386-linuxRedHat5.2-egcs.tar".
On Windows you might use WinZip to expand the package At the end of this step you should have a GDT directory containing, among the others, the INSTALL file for you platform containing details about the installation.
Please report any bug of the installation procedure and/or of the software itself to
