Changes

• Enable choosing default implementation by using the option ``--with-default-graph-impl`` at configure time.

• The Vaucanson library
  • The following iterator interfaces have been removed: ``deltac``, ``rdeltac``, ``delta_state_iterator``, ``rdelta_state_iterator``.
  • New interface ``parse_letter`` to check whether a character string represents a single letter of an alphabet or not.
  • Add an implementation of the reduce algorithm for automata with weights in a division ring.

• Automaton library
  • New program quotkbaseb.

• XML
  • Support of Xerces 3.0.

• TAF-Kit
  • ``$VCSN_DATA_PATH`` now supports colons.
  • New instance: ``vcsn-char-r`` for automata on a free monoid of char and with weights in R (implemented as floats).
  • New command: ``realtime-exp``.

• Demo
  • New Demo ``ORR_iterate``.

• Many bug fixes.

More informations on updates are provided in the NEWS file of the package.

Requirements

C++ compiler

G++ 4.x

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, or libxerces-c28 and libxerces-c28-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

./configure CC=gcc-4.1 CXX=g++-4.1
