## 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 ...
