Compiling D2X-Rebirth Sourcecode on a *NIX System

This file describes how to compile D2X-Rebirth from Source.


Requirements

   1.
      C/C++ compiler (gcc/g++)
   2.
      SCons
   3.
      SDL(-devel)
   4.
      PhysFS(-devel)
   5.
      GLU/GL
   6.
      NASM (optional for Assembler-based Texture-mapper in non-OpenGL Build)


Compiling

The SConstruct file provides various options to compile this program.
To get a full list of all available commands, type scons -h within the Source directory.

Currently, the following variables are supported:

'sharepath=DIR'   (*NIX only) use DIR for shared game data. (default: /usr/local/share/games/d2x-rebirth)
'sdl_only=1'      don't include OpenGL, use SDL-only instead
'sdlmixer=1'      (*NIX only) use SDL_Mixer for sound (includes external music support)
'asm=1'           use ASSEMBLER code (only with sdl_only=1, requires NASM and x86)
'debug=1'         build DEBUG binary which includes asserts, debugging output, cheats and more output
'profiler=1'      do profiler build
'console=1'       build with console support !EXPERIMENTAL!
'editor=1'        build editor !EXPERIMENTAL!
'arm=1'           compile for ARM architecture

‘sdlmixer’ as well as ‘editor’ are currently *not* supported and may not work.

To compile the source, type:

scons


If you wish to add additional commands, just add them to the scons command.
Example:

scons sdl_only=1 no_asm=1


To install the compiled binary to your system (/usr/local/bin/), type (as root):

scons install

You can also add the ‘install’ command while compile-time. SCons will compile and install the binary right after that.

To clean up the source directory after installation, type:

scons -c


Needed files

Since D2X-Rebirth is a Sourceport of the Descent2-Engine you will need the Game-Content data files to run the game.

Following files are needed to run the game:

descent2.ham
descent2.hog
descent2.s11
descent2.s22
alien1.pig
alien2.pig
fire.pig
groupa.pig
ice.pig
water.pig
intro-h.mvl and/or intro-l.mvl
other-h.mvl and/or other-l.mvl
robots-h.mvl and/or robots-l.mvl

These files - except the Movies (*.mvl) - are archived in the file

descent2.sow

on the Descent2 CD-Rom.
This is an ARJ-archive and can be extracted with an adapted archiver like ‘unarj’ or by installing the game on a Windows/DOS system.

Those files need to be copied to the Sharepath, which is (if not specified with the SCons ‘sharepath’-variable) /usr/local/share/games/d2x-rebirth/


Optional files

D2X-Rebirth is expandable. You can add additional content to the game.

Supported content:

    *
      Vertigo series AddOn
      Can be added by copying the files

      d2x-h.mvl and/or d2x-l.mvl
      hoard.ham

      to the Sharepath and

      d2x.hog
      d2x.mn2

      to ‘missions/’ subdirectory in the Sharepath. All these files should be located on the ‘Vertigo Series’ CD-Rom

    *
      Custom/AddOn missions
      Those can be found on several websites. Add them to the game by copying them to subdirectoy ‘missions/’ of the Sharepath.

    *
      Language Packs
      German translation: http://www.dxx-rebirth.de/download/dxx/res/D2XBDE01.zip
      Copy the txb-files to the Sharepath. Will be activated automatically


Launching the program

After compiling and installing, the program can be launched with the command

d2x-rebirth-gl

or - if it has been compiled with SCons parameter ‘sdl_only=1’ -

d2x-rebirth-sdl

To see a full list of available command-line options append ‘-h’, ‘-?’ to the command or refer file

d2x.ini


The game will create a config-directory in the Home directory of the user called ‘.d2x-rebirth’.
It is used to read/save

    *
      Configuration files
    *
      Pilot profiles and Savegames
    *
      Demos
    *
      Screenshots
    *
      d2x.ini for parsing command-line arguments

Thanks to PhysFS it can also be used as a replacement for Sharepath directory
