This code is a compatibility layer; it provides a binary and source compatible API for programs written against SDL 1.2, but it uses SDL 2.0 behind the scenes. If you are writing new code, please target SDL 2.0 directly and do not use this layer.
...

AFAIK looks like a wrapper for SDL1 to use SDL2 (if I'm not mistaken)

@HunoPPC

Hi, changed/updated BeWorld's wipeout fork:

[render_gl_legacy.c]:
//AMIGAOS4
#elif defined(__amigaos4__)
// #include <SDL2/SDL.h>
// #include <SDL2/SDL_opengl.h>
#include <EGLSDL2/SDL.h>
#include <EGLSDL2/SDL_opengl.h>


and in Makefile[.amigaos4]:
L_FLAGS := $(L_FLAGS) -lSDL2egl_wrap -legl_wrap -lauto

build without problems, and runs with all textureet all

GREAT JOB MAN!!!!!!!


NOTE: if I don't use "-lauto" I get:
/SDK/local/newlib/lib/libegl_wrap.a(egl_wrap.o): In function `OpenDynLibs()':
egl_wrap.cpp:(.text+0x2d36): undefined reference to `ITimer'

/SDK/local/newlib/lib/libegl_wrap.a(esGlu.o):esGlu.c:(.text+0x966): more undefined references to `ITimer' follow

isn't possible to add/open Timer/ITimer so to get rid of -lauto switch?

@kas1e

if you use RAWBInfo, then juts on WBStartup prefs click on entry and you should see "Start priority" and set it to a lower value so it starts last one.

Not sure but think tooltype is "PRIORITY=<value>"

To get rid of alignment error:

I had to change line 366 as follows (in platform_sdl.c)

sdl_path_userdata = SDL_GetPrefPath("", "wipeout");
...

@SinanSam460

tested on my SM460ex and works fine slooooow (~8 fps), but works!!!

GREAT job man(s)!!!!

@SinanSam460

GREAT. will try it tomorow

THXaLOT

@kas1e

IMO is not in object.c the problem, the problem is that author decided to use its own memory management (sort of) in mem.c/.h
Maybe to make it easier or dunnot.

@SinanSam460

Not on my miggy right now (but it was just for testing). IIRC at top object.h:
#pragma pack(2)

or maybe #pragma pack(4)

and at bottom:
#pragma pack()

EDIT: forget this silly post, re-tested and got same line (58) crash/allignment issue.

@HunoPPC

yep, same here, but if I add inside object.h (IIRC)
#pragma pack(2)
then such crash/alignment issue "goes down" to line ~76 approx.

Unarchived BeWorld sources to RAM:, added couple of 'defined(__amigaos4__)' and changed to "sdl_path_userdata = SDL_GetPrefPath("", "wipeout");" build and still working here.
I too thinik maybe is just luck how objects are linked, but ¿:-/

http://jabirulo.byethost13.com/temp/wipegame_BEWORLD.7z

Maybe is the way it "allocates memory" in mem.c/.h?

Can the "#pragna pack(whatever_value)" help/solve such allignment issue?

@SinanSam460

YES!! with such change BeWorld sources run ok under my SAM460ex no allignment issues.

But fonts still aren't rendered correctly.

@smarkusg

and using sam460 (AMCC PPC460EX) in QEMU does it work too?

@SinanSam460

Can you test the version attached smarkusg in #37 (https://www.amigans.net/modules/newbb/ ... id=142720#forumpost142720)?

Tested here and fails with alignment on my sam460.

@rwo

I just tested with ReAction demos LB_Example.c and acts a little weird, when I resize window maybe it needs "2 resizes" to text get wrapped on 2 (3) lines.



Then when I shrink window width, text gets cutted, I shrink a little again an then I get:
Demo of ListBrowserNode
features

and same to get:
Demo of
ListBrowserNode
features

@SinanSam460

Great no more LSD-ish colors!!!!
Keep the good work mate!

@kas1e

I Downloaded BeWorld github (fix branch) and recompiled, and it just hangs when loading .PRM files ¿:-/

So I'm (like Sinan) applying step by step such patches and see where it hangs.

<thinking_loud>
Maybe MoprhOS GL library doesn't use GLES2 (as ours, and dunnot if there are "big" diffs between GL and GLES2 or "things" are applied differently on our 3Dgfx system VS mos 3Dgfx system) and some things do work with BeWorld's fixes and others don't.)
</thinking_loud>

EDIT1: and now such brach (fix) doesn't exists ¿:-/
his ain branch doesn't have render_gl_legacy,c

@LiveForIt

thx, still think is some endianess issue with textures/colors/..., 'cos audio was garbled and changing:

SDL_OpenAudioDevice(...
#ifdef __amigaos4__
.format = AUDIO_F32SYS,
#else
.format = AUDIO_F32,
#endif
...

now audio works fine (or just I'm lucky)

@Skateman

yep, applied issue 56 patches/fixes, but no changes on colors/textures/.. ¿:-/

but maybe is 'cos I'm using different fork, as main & beworld crashes here on loading *.PRM (textures?) files.
