To run it:
./doom -iwad DOOM.WAD
Also, run the remote control app to control it for now.
It is found in the remote control folder, run it as so:
./doomgeneric-vector-input robot-ip-here
(to compile it, run gcc doomgeneric-vector-input.c -o doomgeneric-vector-input -lSDL2)
On Arch (run this from your home directory):
wget https://releases.linaro.org/components/toolchain/binaries/latest-7/arm-linux-gnueabi/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabi.tar.xz
tar xf gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabi.tar.xz
export PATH=~/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabi/bin:$PATH
Then to compile:
make -f Makefile.vector (you may need to clean if it doesn't want to compile)
Alternatively, and maybe more correctly, you can use the compiler for vector:
cd ~
mkdir compiler && cd compiler
wget https://github.com/os-vector/wire-os-externals/releases/download/5.3.0-r07/vicos-sdk_5.3.0-r07_amd64-linux.tar.gz
gunzip vicos-sdk_5.3.0-r07_amd64-linux.tar.gz && tar -xvf vicos-sdk_5.3.0-r07_amd64-linux.tar
export PATH=~/compiler/prebuilt/bin:$PATH
For the vector toolchain, run Make -f Makefile.vector.propercompiler

The purpose of doomgeneric is to make porting Doom easier. Of course Doom is already portable but with doomgeneric it is possible with just a few functions.
To try it you will need a WAD file (game data). If you don't own the game, shareware version is freely available (doom1.wad).
Create a file named doomgeneric_yourplatform.c and just implement these functions to suit your platform.
- DG_Init
- DG_DrawFrame
- DG_SleepMs
- DG_GetTicksMs
- DG_GetKey
| Functions | Description |
|---|---|
| DG_Init | Initialize your platfrom (create window, framebuffer, etc...). |
| DG_DrawFrame | Frame is ready in DG_ScreenBuffer. Copy it to your platform's screen. |
| DG_SleepMs | Sleep in milliseconds. |
| DG_GetTicksMs | The ticks passed since launch in milliseconds. |
| DG_GetKey | Provide keyboard events. |
| DG_SetWindowTitle | Not required. This is for setting the window title as Doom sets this from WAD file. |
At start, call doomgeneric_Create().
In a loop, call doomgeneric_Tick().
In simplest form:
int main(int argc, char **argv)
{
doomgeneric_Create(argc, argv);
while (1)
{
doomgeneric_Tick();
}
return 0;
}
Sound is much harder to implement! If you need sound, take a look at SDL port. It fully supports sound and music! Where to start? Define FEATURE_SOUND, assign DG_sound_module and DG_music_module.
Ported platforms include Windows, X11, SDL, emscripten. Just look at (doomgeneric_win.c, doomgeneric_xlib.c, doomgeneric_sdl.c). Makefiles provided for each platform.
You can try it directly here: https://ozkl.github.io/doomgeneric/
emscripten port is based on SDL port, so it supports sound and music! For music, timidity backend is used.
