  More informations on updates are provided in the [{{SERVER}}/dload/vaucanson/1.2.91/NEWS.pdf NEWS] file of the package.

== Requirements ==

;C++&nbsp;compiler: G++ 4.0 and 4.1
;XML: The XML I/O system is based on the use of the Apache Xerces C++ library version 2.7+ (http://xml.apache.org/xerces-c/). (On Ubuntu/Debian, install the following packages: libxerces27 and libxerces27-dev)
;Graphviz: The display of automata is made using AT&T Graphviz library. (On Ubuntu/Debian, install the following package: graphviz)
;Boost: Boost provides free peer-reviewed portable C++ source libraries. (On Ubuntu/Debian, install the following packages: libboost-dev, libboost-serialization-dev, libboost-graph, libboost-graph-dev)
;Ncurses: needed for building the TAF-KIT. (On Ubuntu/Debian, install the following packages: libncurses5, libncurses-dev).

== Known Problems ==

Vaucanson is known not to work properly with Apple's G++ 4.0.0 on Tiger.
Actually, it seems that it is G++ 4.0.0 which is known not to work properly:
other library face similar issues.  We don't know how to solve the problem,
avoid it by specifying another compiler. For instance

<nowiki>
./configure CC=gcc-4.1 CXX=g++-4.1
</nowiki>

Vaucanswig is not working properly with this version.
