SDL2 port when ? - Page 3

Magnate · September 23, 2018, 09:07

Hi Shirish, thanks for the email. It's funny how life happens sometimes, I was thinking only the other day it's time I updated Angband in Debian, 4.x must be pretty mature now and I expect some free time this fall ... and lo, something happens to pull me back.

I can't promise anything soon, but months rather than years. I'll start with a bog-standard package of Angband 4.x, then I'm going to fix up angband-audio, then I'll see if I can help on SDL2.

Derakon, Nick - hope you're well.

Good to hear from you! Am currently recovering from surgery according to plan, so let's call that well

Good to see you, Magnate! I'm doing decently well. Life continues on, no great peaks nor abyssal chasms.

I sent the pull request:
https://github.com/angband/angband/pull/502

For those who are interested in compiling it (instructions for Debian-based systems!):

You'll need three libraries: the "base" SDL2, SDL2_ttf (fonts stuff) and SDL2_image (loading .png files and such). Also, their dependecies (Freetype, zlib and co). If you want sounds, you'll also need SDL2_mixer. In short:

Code:

apt-get install libsdl2-dev libsdl2-ttf-dev libsdl2-image-dev libsdl2-mixer-dev

Clone the repo and switch to sdl2 branch:

Code:

git clone https://github.com/t4nk074/angband
git checkout sdl2

Configure Angband without any frontends (just in case):

Code:

cd angband
./autogen.sh
./configure --with-no-install --disable-curses --disable-x11

(I think other stuff is disabled by default)

Now compile the game using Makefile.sdl2:

Code:

cd src
make -f Makefile.sdl2

If you want sounds, use this instead:

Code:

cd src
SOUND=yes make -f Makefile.sdl2

Now it should work... well, works for me

Code:

cd ..
./angband

Let me know if there are any problems!

Shouldn't this be from inside the repo. I have done the following -

Code:

~/games$ git clone https://github.com/t4nk074/angband angband-t4nk074
Cloning into 'angband-t4nk074'...
remote: Counting objects: 56527, done.

Resolving deltas: 100% (45476/45476), done.

Then -

Code:

~/games$ cd angband-t4nk074/
~/games/angband-t4nk074$ git checkout sdl2
Branch 'sdl2' set up to track remote branch 'sdl2' from 'origin'.
Switched to a new branch 'sdl2'

I would be updating my answer as I do the next steps.

You should probably run ./configure with --disable-sdl-mixer too. (Hi magnate!)

Hi all,

I retried and failed -

Code:

~/games/angband-t4nk074$ ./autogen.sh
*info* running aclocal (-I m4)
*info* running autoheader
*info* running autoconf

and then - will be sharing just the start and end messages -

- SDL sound                               Disabled

Still got the same issue -

Code:

shirish@debian:~/games/angband-t4nk074$ cd src/
shirish@debian:~/games/angband-t4nk074/src$ SOUND=yes make -f Makefile.sdl2
        CC snd-sdl.c           
snd-sdl.c:25:10: fatal error: SDL/SDL.h: No such file or directory
 #include <SDL/SDL.h>
          ^~~~~~~~~~~
compilation terminated.
make: *** [Makefile.sdl2:100: snd-sdl.o] Error 1

Perhaps it should be -
SDL2/SDL.h

Code:

$ dpkg -L libsdl2-dev | grep SDL.h
/usr/include/SDL2/SDL.h
/usr/include/SDL2/SDL_haptic.h
/usr/include/SDL2/SDL_hints.h

I was able to fix it by doing in sdl2.c -

Code:

$ cat snd-sdl.c | grep include
 *    are included in all such copies.  Other copyrights may also apply.
#include "angband.h"
#include "init.h"
#include "sound.h"
#include <SDL2/SDL.h>
#include <SDL2/SDL_mixer.h>

just changed SDL/SDL.h and SDL/SDL_mixer.h to SDL2/SDL.h and SDL2/SDL.mixer.h

and was able to compile -

Code:

~/games/angband-t4nk074/src$ SOUND=yes make -f Makefile.sdl2
        CC snd-sdl.c           
      LINK angband             
cp angband ..

Ah, I see. I have SDL1 headers installed, so gcc looks into /usr/include and there is "SDL" directory there. You have only SDL2, so you have /usr/include/SDL2 (but not /usr/include/SDL). So it fails to find it (SDL_mixer API hasn't changed between 1 and 2).

Anyway, looks like you're close

snd-sdl.c has two lines:

Code:

#include <SDL/SDL.h>
#include <SDL/SDL_mixer.h>

(lines 25 and 26)

Those need to be replaced with:

Code:

#include <SDL.h>
#include <SDL_mixer.h>

@t4nk, I just did that, see above

Btw we don't seem to have any graphics, it still shows up in ASCII mode with the skeletons as background.

I did try -

Code:

~/games/angband-t4nk074$ ./angband -g -ssdl -msdl2

Also angband doesn't seem to have any options for windowed mode from what all I could see/gather -

Code:

$ ./angband --help
Usage: angband [options] [-- subopts]
  -n             Start a new character (WARNING: overwrites default savefile without -u)
  -l             Lists all savefiles you can play
  -w             Resurrect dead character (marks savefile)
  -g             Request graphics mode
  -x<opt>        Debug options; see -xhelp
  -u<who>        Use your <who> savefile
  -d<dir>=<path> Override a specific directory with <path>. <path> can be:
    scores (default is /home/shirish/games/angband-t4nk074/lib/scores)
    gamedata (default is /home/shirish/games/angband-t4nk074/lib/gamedata)
    screens (default is /home/shirish/games/angband-t4nk074/lib/screens)
    help (default is /home/shirish/games/angband-t4nk074/lib/help)
    info (default is /home/shirish//.angband/Angband/info)
    pref (default is /home/shirish/games/angband-t4nk074/lib/customize)
    fonts (default is /home/shirish/games/angband-t4nk074/lib/fonts)
    tiles (default is /home/shirish/games/angband-t4nk074/lib/tiles)
    sounds (default is /home/shirish/games/angband-t4nk074/lib/sounds)
    icons (default is /home/shirish/games/angband-t4nk074/lib/icons)
    user (default is /home/shirish//.angband/Angband)
    save (default is /home/shirish/games/angband-t4nk074/lib/save)
                 Multiple -d options are allowed.
  -s<mod>        Use sound module <sys>:
     sdl   SDL_mixer sound module
        
  -m<sys>        Use module <sys>, where <sys> can be:
     sdl2   SDL2 frontend

Also for the mixer, shouldn't it be sdl2_mixer. I haven't been able to hear any sound
