Doom64EX is a reverse-engineering project aimed to recreate Doom64 as close as possible with additional modding features.

NOTE for Linux users: As of Feb. 24, 2016, the save data is located in $XDG_DATA_HOME/doom64ex (typically ~/.local/share/doom64ex) and not in ~/.doom64ex. The files can be safely moved to their new home.

• release - stable release, verified and tested on SteamOS / Debian Jessie.
• master - tracks the upstream master tree, and is not guarenteed to work / build.

• SDL2
• SDL2_net
• zlib
• libpng
• FluidSynth
• gcc-5 or clang-3.6 (>=3.6.2) if building from the master tree

For Debian users:

sudo apt-get install cmake debhelper libsdl2-dev libsdl2-net-dev zlib1g-dev libpng12-dev libfluidsynth-dev

Clone this repo

$ git clone https://github.com/svkaiser/Doom64EX

Create a new directory inside the repo root where compilation will take place

$ mkdir Doom64EX/temp
$ cd Doom64EX/temp

Run cmake and make

$ cmake .. && make

Install doom64ex

# make install

Doom64EX needs the Doom 64 data to be present in any of the following directories:

• The directory in which doom64ex resides
• $XDG_DATA_HOME/doom64ex (eg. ~/.local/share/doom64ex)
• /usr/local/share/games/doom64ex
• /usr/local/share/doom64ex
• /usr/share/games/doom64ex
• /usr/share/doom64ex

The data files are:

• kex.wad (Generated by cmake)
• doom64.wad
• doomsnd.sf2

To generate the two latter files, acquire a Doom64 ROM and run:

$ doom64ex -wadgen PATH_TO_ROM

This will generate the required files and place them in $XDG_DATA_DIR/doom64ex.

After this you can play.

$ doom64ex

If you have trouble generating the wad file, try making a directory, and running wadgen in that directory. For some reason, the output tries to write to the current name of the rom.

mkdir wad_output && cd wad_output
doom64ex -wadgen ../doom64.z64

When you generate the doom files with the executable, check the permissions:

Sucessfully created /home/desktop/doom64.wad
Writing Soundfont File...

Sucessfully created /home/desktop/doomsnd.sf2
desktop@steamos:~$ ls -la /home/desktop/doom64.wad
-r-------- 1 desktop desktop 8641888 Jul 30 07:25 /home/desktop/doom64.wad

desktop@steamos:~$ ls -la /home/desktop/doomsnd.sf2
-r-------- 1 desktop desktop 5429302 Jul 30 07:25 /home/desktop/doomsnd.sf2

Try chmod 755 on those files, and things may work fine.
