dlvhex for Debian/Ubuntu

We provide pre-compiled packages of dlvhex 1.X at Debian/Ubuntu packages for ASP systems.

Note: These packages are outdated! There are currently no pre-compiled packages of dlvhex 2.X available. Please build it from source. However, we offer a funded master thesis on the development of a release management system and building new packages; if you are interested please drop us an e-mail.

Development Version

The current development version of dlvhex plus plugin-suite is hosted at github in the hexhex Collection.

The dlvhex core code can be retrieved by executing

git clone --recursive git://github.com/hexhex/core.git

(readonly) or for read-write access (if you are allowed to commit) with

git clone --recursive git@github.com:hexhex/core.git

Confer MAINTAINER-README and README for the list of packages you need to compile the development version of dlvhex.

You can checkout the plugins using the same command (do not forget --recursive) on the other repositories which are parte of the hexhex organization.

IMPORTANT!

Whenever you use a git version of dlvhex, do not forget to clone with

git clone --recursive

and do not forget to run

./bootstrap.sh

after cloning. (After ./bootstrap.sh you can continue with ./configure as shown below.)

Per default, dlvhex will build with gringo and clasp which is contained in the dlvhex tarball.

If dlv is found in the path, then dlv can be used as backend.

To work with the DL-plugin, you will also need the DL-reasoner RacerPro.

To work with the WordNet-plugin, you will also need Wordnet installed.

Compiling Source Packages Primer

Requirements for compiling dlvhex: the inevitable Boost C++ libraries (available as packages for all major distributions).

dlvhex is installed with the usual sequence:

./configure
make
make install

If you don't want a system-wide installation or don't have root-permissions, use

./configure --prefix=/path/to/dir

where /path/to/dir is the desired target prefix. There, the usual bin/ and lib/ will be created, if necessary.

For installing a plugin, again do:

./configure
make
make install

The plugin library will be installed in ${prefix}/lib/dlvhex/plugins, where ${prefix} was determined by the dlvhex installation. If you use

./configure --enable-userinstall

instead, the plugin will be put in ~/.dlvhex/plugins/.
