EDuke32 is a fork of the JFDuke3D port of Duke Nukem 3D (aka Duke3D), merging it with EDuke to provide many new features for mod authors. Also included is a map editor (mapster32). To play the game, you will need the DUKE32.GRP file from either the Duke Nukem 3D CD-ROM, or from the shareware version of Duke Nukem 3D. For convenience, the shareware GRP file has been packaged as eduke32_shareware_data, also available from slackbuilds.org. See README_game_data.txt eduke32 is an SDL application. It can be built with either SDL 1.2 (included in Slackware), or SDL 2 (from SlackBuilds.org). By default, SDL 2 is used if it's installed, otherwise SDL 1.2 is used. To force building with SDL 1.2, export SDL2=no in the environment before building eduke32. If you want to play the HRP (High Resolution Pack), get the eduke32_hires_pack package from slackbuilds.org. To hear the in-game music, either use the Music Pack (see eduke32_hires_pack), or else install a set of MIDI patches (either freepats or eawpats) from slackbuilds.org. The game looks for /etc/timidity/timidity.cfg, but timidity doesn't actually have to be installed. By default, the Build utilities (kextract kgroup transpal wad2art wad2map) are built by this script and installed in /usr/games. If you don't want these, you can set BUILD_UTILS=no in the environment before running the SlackBuild script. Note for 64-bit users: Despite the "32" in the name, this software builds and runs just fine as 64-bit native binaries :)
