Download Binaries

You can download pre-built stable release versions of dlvhex and its plugins from this page.

You will need the dlvhex core in any case. It provides base functionality such as the evaluation of ASP- and HEX-programs and can be extended with the plugins listed below.

If you are using operating systems which are not listed below, or if you prefer to build from sourcecode for other reasons, please visit the Download Sourcecode page.

Note that this page is only about dlvhex 2.X because dlvhex 1.X is no longer supported and should not be used anymore. However, if you depend on 1.X (e.g. because a plugin is not available for 2.X), you may visit the old download page (distribution as sourcecode only).
