INSTALLATION

* GNS3 dependencies:

- Qt 4.5.1 (or higher)
- Python 2.5 (or higher)
- Sip 4.5 (or higher)
- PyQt 4.5 (or higher)

* WINDOWS users:

Download the GNS3 all-in-one for Windows on http://www.gns3.net (~12 MB)
This program will install a binary version of GNS3 as well as Dynamips, Qemu and WinPCAP.

Recommendation: Dynamips has better performances on other platforms such as Linux or Mac OS X.

* Linux users:

On Linux you just need to install a package called python-qt4 (or similar). Instead, you can compile all the dependencies manually.

A debian package is now available, until officially released with Debian/Ubuntu follow instructions
on http://gpl.code.de/oswiki/GplcodedeApt and install "gns3" package (it might not be up-to-date).

* MacOS X users:

Method 1.

1. Install the Apple Devs Tools (on your Mac OS X DvD or download it on ADC account). Run and install XcodeTools.mpkg.

2. Download Python 2.6 for MacOS X on http://www.python.org/download/ and install it.

3. Download Qt librairies for Mac on http://qt.nokia.com/downloads and install it. 

	Please note GNS3 doesn't run properly with Qt 4.6.1 and 4.6.2. Version 4.5.3 is currently recommended.

4. Download SIP on http://www.riverbankcomputing.com/software/sip/download, compile and install it:

	Version 4.9.3 is currently recommended.

	Open terminal and cd into the folder you downloaded the tar file and compile via the following commands (example for SIP 4.9.3):

	Macintosh:$  tar xvzf sip-4.9.3.tar.gz
	Macintosh:$  cd sip-4.9.3
	Macintosh:sip-4.9.3$  python configure.py
	Macintosh:sip-4.9.3$  make
	Macintosh:sip-4.9.3$  make install

5. Download PyQt on http://www.riverbankcomputing.com/software/pyqt/download, compile and install it:

	Version 4.6.2 is currently recommended.

	Again, run the following commands to decompress and compile PyQt (example for PyQt 4.6.2):

	Macintosh:$  tar xvzf PyQt-mac-gpl-4.6.2.tar.gz
	Macintosh:$  cd PyQt-mac-gpl-4.6.2
	Macintosh:PyQt-mac-gpl-4.6.2$  python configure.py
	Macintosh:PyQt-mac-gpl-4.6.2$  make
	Macintosh:PyQt-mac-gpl-4.6.2$  make install

6. Download and start GNS3.


Method 2 (this can take a few hours as everything is compiled).

1. Download and install MacPorts http://guide.macports.org/#installing (you will need the Apple Devs Tools).

2. Open a terminal and install GNS3 dependencies. 

	To prevent MacPorts to install the last version of the dependencies (which may not work properly with GNS3), you have to specify the needed version.
	
	Currently, it is recommended to install Qt 4.5.3, SIP 4.9.3 and PyQt 4.6.2.

	Macintosh:$ sudo port install python26
	Macintosh:$ sudo port install py26-sip @4.9.3_0
	Macintosh:$ sudo port install py26-pyqt4 @4.6.2_0
	Macintosh:$ sudo port install qt4-mac @4.5.3_0

3. Download and start GNS3
