Building EDuke32 on Linux

Compiling From Source

Installation Notes

• You need an actual copy of Duke Nukem 3D. The shareware version can be found here
• Proper 3D acceleration drivers. NVIDIA has classically had the best Linux drivers.
• Proper MIDI install. The EDuke32 will appear to "randomly" crash without one. Use timidity for an easy software midi solution.

Getting source files

• Current version (You need to install the subversion program) :

svn co https://eduke32.svn.sourceforge.net/svnroot/eduke32/polymer/eduke32

• Source tarballs (Lite subversion snapshots, it does not include metadata, Apple compiled libraries, third-party jaudiolib and Photoshop files).
• Old and Older versions.

Prerequisites for the build

EDuke32 requires some development files installed before you can properly build.

• Basic dev environment (GCC >= 4.3.3, make, etc)
• LibStdc++ (or LibSupc++, the cut down version. These might not be necessary at all, try commenting out '-lsupc++' in build/Makefile.shared)
• Nasm (optional)
• LibGL and LibGLU (optional)
• LibSDL >= 1.2.10 or 1.3
• LibSDL Mixer > 1.2.6
• LibVorbis >= 1.1.2
• LibPNG >= 1.2.13 (optional)
• LibVPX >= 0.9.6 (optional)
• LibGTK+ >= 2.8.0 (optional)

On Debian / Ubuntu

sudo apt-get install build-essential nasm libgl1-mesa-dev libglu1-mesa-dev libsdl1.2-dev libsdl-mixer1.2-dev libvorbis-dev libpng12-dev libvpx-dev libgtk2.0-dev timidity freepats

On Fedora 14-16

sudo yum groupinstall "Development Tools"

sudo yum install SDL-devel SDL_mixer SDL_mixer-devel SDL_image-devel nasm libstdc++-devel libstdc++-static libpng-devel libvpx-devel

Build the EDuke32

In a terminal window move to the EDuke32 sources folder and type make.

NOTE: with eduke32_src_20080924 and older GCC versions (< 4.3) remove; -finline-small-functions -fpredictive-commoning options from debug= options in eduke32/Makefile and build/Makefile. Newer source releases do not have this problem.

NOTE2:

If building fails with GCC version 4.4.X, try: make OPTLEVEL=0

If it fails again, you can try with another version of GCC, for example: make CC=gcc-4.3

Build options

It is possible to define some options during the build. Just add them before or after the 'make' command.

Example: make USE_LIBPNG=1

Various options

Options	Description	Default value
PRETTY_OUTPUT	Use colored output.	1

Engine options

Options	Description	Default value
USE_OPENGL	Enable basic OpenGL Polymost renderer.	1
POLYMER	Enable fancy Polymer renderer.	1
NOASM	Disable the use of inline assembly pragmas. Should be enabled on 32-bit Pentium compatible processors only.	0 (disabled for x86_64, hardcoded, because the ASM is 32-bit)
LINKED_GTK	Enable compile-time linkage to GTK+.	0
WITHOUT_GTK	Do not compile GTK+ code.	0
BUILD32_ON_64		0
NEDMALLOC	Use nedmalloc instead of malloc().	0
USE_LIBPNG	Compile with libpng (used to make screenshots in the PNG format). This may or may not require libz.	0
USE_LIBVPX	VP8 video codec used as an alternative to the ANM file format (only works if compiled with OpenGL support).	1

Debugging/Build options

Options	Description	Default value
RELEASE	No debugging.	1
DEBUGANYWAY	Include debug symbols even when generating release code. The following arrays be allocated statically: spriteext, spritesmooth, sector, wall, sprite, tsprite, while necessarily disabling the clipshape feature (because it relies on setting sector/wall to different malloc'd block temporarily). Really only useful with CC=clang.	0
KRANDDEBUG	Include logging of krand() calls for debugging the demo system.	0
EFENCE	Compile with Electric Fence for malloc() debugging.	0
DMALLOC	Compile with dmalloc for malloc() debugging.	0
OPTLEVEL	GCC optimization strategy. Values above 2 can cause crashes.	2
ARCH	Define options specific to the CPU architecture.	empty (except for i686)
PROFILER		0
MUDFLAP		0
LTO	Enable link-time optimization, for GCC 4.5 and up.	0

Confirm successful compile

These files should now be present in the EDuke32 directory.

• mapster32 (executable)
• eduke32 (exectuable)

Run the game!

You need to have the original Duke Nukem 3D files and the newly created EDuke32 executables in the same place. So, you could create a new folder (example eduke32_linux) and copy the original game files and the newly created EDuke32 executables there.

To run the game open up a terminal window, move to the proper directory and type :

./eduke32

• To use the Polymost High Resolution Pack you can pass the -g parameter :

./eduke32 -g duke3d_hrp.zip polymost_hrp_update-*.zip

• To use the Polymer HRP you can pass the -g parameter :

./eduke32 -g polymer_hrp.zip polymer_upd.zip

Note that polymer_upd.zip may not be available. It is also possbile to add additional packs such as remade music and Z-Pack.

• Using the autoload folder :

Copy mods or HRP files in the $HOME/.eduke32/autoload folder and it will be automaticaly loaded without additional parameters.

Installing EDuke32 globally

Why

Installing EDuke32 as an application that you could run anywhere brings some useful advantages and is surprisingly easy to do.

EDuke32 will use the directory you are currently in as the directory to work in, as well as ~/.eduke32 (/home/yourname/.eduke32). This means that you could have a directory, copy a Duke Nukem TC (or mod) in there, cd to that directory and run the global EDuke32 binary without having to make even more copies of the same EDuke32 binaries. EDuke32 will adapt to use the GAME/USER.CON files it finds in the CURRENT directory.

How

All you'll have to do to get EDuke32 to run from anywhere is copy the eduke32 and mapster32 binaries to /usr/local/bin. After doing this, copy the duke3d.grp file to /usr/local/share/games/eduke32 or ~/.eduke32 (it's hidden, so try to cd to it or show hidden files). After this you'll be able to run EDuke32 from any directory on your hard disk!

Notes

Lowercase/Uppercase problems

Maps with extra resources Some maps that include extra resources might have trouble finding these new files (for example, an older version of Duke Plus won't be able to find Step#.wav and Grate#.wav sounds). The EDuke32 log will output a "file not found" error every time this happens. To fix this, change the names of these files to match the exact case given in EDuke32's log (for example, GRATE#.wav instead of Grate#.wav).

ART file inconsistency While most standard resources are referred to as UPPERCASE by EDuke32 (for example, GAME.CON), ART files are not as consistent and should be renamed to lowercase if you want to use custom art (tiles014.art instead of TILES014.ART).

Running with HRP Notes

If you want to run Polymer with the HRP you will need to provide the path to polymer_hrp.zip (even if its installed globally): eduke32 -g /path/to/polymer_hrp.zip.

Running EDuke32 with an ATI card is slow for some users. One user has had success with a Radeon 4850 and Fedora 12 with the open source default driver plus the latest Mesa experimental - the game runs smooth and pretty fast.
