## Install Boost and libidn

You have to have boost-devel and libidn-devel installed before compiling Swiften, otherwise it will compile against bundled version of Boost and libidn and Spectrum compilation will fail.

## Install Swiften from git repository:

	git clone git://swift.im/swift

	cd swift

	./scons V=1 swiften_dll=1 Swiften SWIFTEN_INSTALLDIR=/usr/local force-configure=1

	sudo ./scons V=1 swiften_dll=1 Swiften SWIFTEN_INSTALLDIR=/usr/local /usr/local

*Note* - If the output of "./scons" command contains following during the configure stage, you don't have boost-devel or libidn-devel installed during the compilation and *Swiften won't work properly*:

	Checking for C++ header file boost/signals.hpp... no

	....

	Checking for C library idn... no

The proper configure script output looks like this:

	scons: Reading SConscript files ...

Note that you have to have at least Python 2.5 to build Swiften.

## Install Google protobuf

In Fedora, you just have to install following packages:

	sudo yum install protobuf protobuf protobuf-devel

## Install Libpurple for libpurple backend

You should definitely have latest libpurple, so download Pidgin and compile it, because your distribution probably doesn't have the latest one.

## Install libCommuni for libCommuni IRC backend

The instructions are defined on [libCommuni wiki](https://github.com/communi/communi/wiki).

## Install Spectrum 2

	git clone git://github.com/hanzz/libtransport.git

	cd libtransport

	cmake . -DCMAKE_BUILD_TYPE=Debug

	make

Before running make, check cmake output if the supported features are OK for you. If not, install libraries needed by Spectrum to provide specific feature.

You can also install spectrum using `sudo make install`.
