The Vaucanson library is free software. It is distributed under the conditions of the GNU General Public License (


Changes since 1.2.95

  • Out-of-date documentation has been trashed away. What remains is an overhauled documentation for TAF-Kit that can be read in doc/manual/taf-kit-manual.pdf.
  • Vaucanson library
    • The has_succ_comp() function has been renamed to is_useless(), and its result reversed.
    • Rational expression can be exported into XML.
    • standard_of() and thompson_of have been improved to build the automaton in place.
  • TAF-Kit
    • The has-succ-comp command has been replaced by the is-useless command, following the change in the library.
    • The co-accessible command is now spelled coaccessible.
    • Commands that output rational expression will output XML files if given the -o xml option, and will read XML files if given the -i xml option.
    • Two new instances: vcsn-char-zmin and vcsn-char-zmax.
    • A couple of unusual commands have been removed from the output of --list-commands and are now only shown by the new --list-all-commands option.
 More informations on updates are provided in the NEWS file of the package.


C++ compiler

The display of automata is made using AT&T Graphviz library. (On Ubuntu/Debian, install the following package: graphviz)
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)
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
