   1 D2DF-SDL
   2 ---------
   3
   4 Doom 2D Forever ( http://repo.or.cz/d2df-sdl.git ) adapted for use with the FreePascal Compiler
   5 and ported to SDL 2.0.

   7 Building
   8 ---------
   9
  10 Requirements:
  11 * FPC >= 3.0.2;
  12 * FMODEx >= 4.26.xx or SDL_mixer >= 2.0;
  13 * libenet >= 1.3.13;
  14 * SDL >= 2.0.
  15
  16 Create the "tmp" and "bin" directories beforehand if they don't exist already. Then run
  17
  18 cd src/game
  19 fpc -O3 -Fi../lib/vampimg -Fi../lib/vampimg/JpegLib -Fi../lib/vampimg/ZLib -Fu../lib/vampimg -Fu../lib/vampimg/JpegLib -Fu../lib/vampimg/ZLib -FE../../bin -FU../../tmp Doom2DF.lpr

  21 If you want SDL_mixer instead of FMOD, add -dUSE_SDLMIXER.
  22 If you want the server to be able to forward ports via UPNP, add -dUSE_MINIUPNPC.
  23 If you want to debug game with Holmes, add -dENABLE_HOLMES (not supported in GLES mode).
  24 If you want to render graphics using OpenGL ES, add -dUSE_GLES1.
  25 To build a headless (no video/audio, for dedicated servers) executable, add -dHEADLESS.
  26 Replace -O3 with -g -gl to enable debugging features. Run the game with --gdb when using a debugger to
  27 prevent it from eating exceptions.
  28
  29 Windows binaries will require the appropriate DLLs (SDL2.dll, SDL2_mixer.dll or FMODEx.dll, ENet.dll, miniupnpc.dll),
  30 unless you choose to static link them (see below).

  33 Static Linking
  34 --------------
  35
  36 See ( http://repo.or.cz/d2df-binlib.git ) repo for prebuild dynamic and static libraries.
  37
  38 It is now possible to link windoze LibJIT and ENet as static libs.
  39
  40 First, you need to clone ( http://repo.or.cz/d2df-binlib.git ) (repo with prebuilt windoze libs).
  41 Then, you can use:
  42   -dLIBJIT_WINDOZE_STATIC       -- static LibJIT
  43   -dLIBENET_WINDOZE_STATIC      -- static ENet
  44   -dLIBMINIUPNPC_WINDOZE_STATIC -- static MiniUPNPC
  45
  46 Don't forget to specify lib*.a location with -Fi<...>
  47
  48 I (ketmar) used mingw-gcc 7.1.0 to build static libs; some other .a libs were taken directly from mingw.
  49 building libs is easy: just fire msys, install all dependencies, and do:
  50
  51   ./configure --enable-static --disable-shared && make
  52
  53 This should produce working .a library suitable for static linking.
