### Getting the sources
You have two options to get souces:

*   use prepared tarball/archive with applied patch  
*   use the latest code from version control

#### Using prepared tarball
Download archive file from https://db.tt/0UUO7NKb and extract sources into some folder (for example `~/wireshark`). You should not apply any patches: all patches are included in archive. Goto **Build steps**.

#### Using latest code from version control
If you wish to use the latest code from version control, first ensure that you have a *Subversion* client (if you don't have one, install a client for your platform from https://subversion.apache.org/packages.html).  
To download sources, use "svn co", e.g.

    $ svn co http://anonsvn.wireshark.org/wireshark/trunk/ wireshark 

If you're behind a proxy that doesn't allow Subversion access you can use SSL:

    $ svn co https://anonsvn.wireshark.org/wireshark/trunk/ wireshark

### Applying a patch
Download patch-file from https://db.tt/d4R2DX8c
#### Linux

Then goto WireShark sources folder `$ cd wireshark`and run the following comand:

    $ patch -p0 -i path/to/patch-file/ws_dcbx.patch

#### Windows
For apply patch under windows you can use *TortoiseMerge* (part of TortoiseSVN http://tortoisesvn.net/). Or you can install *patch* on *Cygwin* (http://www.cygwin.com/) and act as in Linux case.

### Required Libraries and Packages
* GTK+ and GLib (http://www.gtk.org/)
* libpcap (http://www.tcpdump.org/) or Winpcap for Windows (http://www.winpcap.org/)
* Perl (http://www.perl.com/)
* Python (http://www.python.org/)
* sed (http://directory.fsf.org/GNU/sed.html)
* flex (http://www.gnu.org/software/flex/)
* bison (http://www.gnu.org/software/bison/bison.html)

### Build steps

#### Linux
Install required libraries and packages:

    sudo apt-get install build-essential automake autoconf libgtk2.0-dev libgtk-3-dev libglib2.0-dev libpcap0.8-dev flex bison

Then goto wireshark sources folder and configure your build directory:

    $ ./autogen.sh
$ ./configure [options]

And finally build by running:

    $ make

**NOTE:**: if build fails with error message `all warnings being treated as errors` run `./configure` with option `--disable-warnings-as-errors`

#### Windows
Building Wireshark under Windows is a bit **complicated**. But there is a detailed **Win32/64: Step-by-Step Guide** on Wireshark site (http://bit.ly/WireSharkWinBuild).
