- - SDL2 port when ? (http://angband.oook.cz/forum/showthread.php?t=9076)

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 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.

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 -

Code:

~/games/angband-t4nk074$ ./configure --with-no-install --disable-curses --disable-x11 --disable-sdl-mixer

checking build system type... x86_64-unknown-linux-gnu

checking host system type... x86_64-unknown-linux-gnu

checking target system type... x86_64-unknown-linux-gnu

.....

.....

configure: creating ./config.status

config.status: creating mk/buildsys.mk

config.status: creating mk/extra.mk

config.status: creating mk/sinclude.mk

config.status: creating src/autoconf.h

config.status: src/autoconf.h is unchanged

- 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 :(

p.s. Hi, Takkaria :)
