WarpOS version of SDL

[grelbfarlk]

There is a reference to AslBase in libauto.a under the MorphOS host but adding -lauto doesn't seem to help.

Are you sure -noixemul is defined? I suppose you used ppc-amigaos configuration in the makefile, which is missing that.

[grelbfarlk]

Yeah I've set -noixemul, to no effect.
I transferred everything over to the A4000 in case somehow it was grabbing things from the Morphos osinclude or something, it's basically the same. Here's where I'm at now:

AslRequester.o(.text+0x3f4): undefined reference to `AllocAslRequestTags(unsigned long, unsigned long,...)'
AslRequester.o(.text+0x40c): undefined reference to `AslRequestTags(void *, unsigned long,...)'

I've tried including everything under the sun, those appear in libamiga.a on the A4000 in the 68k lib folder but adding -lamiga doesn't seem to help either. I think I need to call in my WarpOS expert. Steve House.

Also this is what I changed which has not been cleaned up yet:

#include "AslRequester.h"

#include <stdio.h>
#ifdef WARPOS
#pragma pack(2)
#endif

#ifndef WARPOS
#include <proto/exec.h>
#include <proto/asl.h>
#include <proto/dos.h>
#endif

struct AslIFace *IAsl;
#define MAX_DOS_PATH 260
#ifdef WARPOS
#include <proto/exec.h>
#include <proto/dos.h>
#include <proto/powerpc.h>
#include <proto/asl.h>
extern struct Library *AslBase;
#pragma pack()

#endif

This shit is super weird. Keep notes of all this until I merge everything with my sources!

You can't use 68k libs as the PPC can't jump to 68k code directly. Can't use MorphOS libs due to ABI and API differences.

You have a correct proto/asl.h for WarpOS?

No I don't think so. Made sure it's going to os-includeppc and it gives the AslBase undefined reference that I got earlier.

Ok Steve fixed it.
struct AslIFace *IAsl =;
struct Library *AslBase = NULL;

Assuming because we don't have libauto this was necessary. Now just some missing functions which I'll try to piece together tonight which are:
expf
cosf
sinf

[grelbfarlk]

Ok... so it compiled. I do not agree with the color choices in your program.

[grelbfarlk]

Looks correct on a BE screen. Doesn't seem to want to go fullscreen. I guess it's using the SDL audio driver instead of the AHI one, not sure which would be better. Sound is kinda bad. Looks like it's using 16-bit audio by default. File requester doesn't work when I hit open it says failed to allocate file requestor.

Which SDL version is this? It's always used SDL-audio. SDL-audio goes through AHI.

You need to change audio settings in the program under config. It by default tries to play 48.000Hz playback and minimal buffer. Changing it to 44.100Hz should probably make it better.

The file requester is Asl, which is part of AmigaOS api, so you did not fix that part. :P

Atleast it's getting closer to working as it should. At the moment it's hardcoded to run in 16bit graphics mode, which could be the reason for the weird graphics. You can change that inside src/tracker/sdl-1.2/CGX_main.cpp in the main function.

[Marlon_]

Hmm, I'm curious if I could use the MorphOS cross-toolchain to build WarpOS binaries. Like if I get the proper includes and libs for WarpOS, wouldn't it technically work? Or does the compiler itself do some 68k-PPC mixing when compiling? Maybe worth a try?

[Hedeon]

See gcc-wos4mos on Aminet.

Unfortunately Aminet seems to be down for the moment.

I was just confused by the AudioDriver_AHI.cpp. SDL is 1.2.6.

If I force a BE screenmode the colors are correct.

As Hedeon says below, get his package from Aminet and drop it in gg:
Add -warpup to CFLAGS and LDFLAGS and that's pretty much it.

AudioDriver_AHI.cpp is not finished, it's not compiled at the moment.

Have you tried compiling this for WarpOS?: https://github.com/AmigaPorts/libSDL12

It's SDL-1.2.15 for Amiga platforms.

I'm going to mess with Hedeon's package and see if I can set up a Linux cross-compiler with it.

Yes actually I tried that last night, it was about the same. Voodoo on Mediator really prefer LE modes and Radeon doesn't support BE at all. Voodoo 3 does BE/LE but Voodoo 4 only does LE. So I've got to look at how to switch that.

Isn't elf2exe2 just elf2hunk? I'll do some experiments and see what I come up with.

Good luck.

Elf2exe2 needs warpcollect to convert output of gcc to input for elf2exe2. Maybe elf2hunk doesn't need that and can be called directly. Anyway, see specs file.

Too bad they removed that functionality with gcc 4.6 I think.

As far as I understand from my research, all Elf2exe2 is doing is the same Elf2hunk does.

I found this here:

The spec strings built into GCC can be overridden by using the -specs= command-line switch to specify a spec file.

So, yeah, specs files still work:

But I think the format might be different!

[Marlon_]

Elf2exe2 usage:
./elf2exe2 file.elf file.hunk

Exactly the same way elf2hunk works.

So it should work just the same with warpcollect.
