WarpOS version of SDL

[grelbfarlk]

libSDL_Image_wos.a and libJPEG(_wos).a working. Works with gif and jpeg that I've tried so far, now just to get png.

Had to link in order of -lSDL_Image_wos -ljpeg -lSDL_wos (just so I don't forget this tomorrow).

ppc-amigaos-g++ -warpup -O2 sdltest3.cpp -o SDLrun3-1.elf -lSDL_Image_wos -ljpeg -lSDL_wos

And you had to adjust your makefile

[grelbfarlk]

libPNG(_wos).a done too and works.
Again, not going to remember this:
ppc-amigaos-g++ -warpup -O2 sdltest3.cpp -o SDLrun3-1.elf -lSDL_Image_wos -lpng -lz -ljpeg -lSDL_wos

00000010  00000090 00000000  00000040 00000000  |...........@....|

same src code, 1st build with sas/c, 2nd with gcc.

As far as I can see: When set to GCC mode and using Amiga Classic OS as target OS with the PPC link libraries and doing a simple Hello World in C, the object file is in Amiga hunk format. The resulting executable is a WarpOS executable in this case.

HOWEVER:

With PPC it is in Extended hunk format (I see hunk 0x4E9 in the object file, next to 0x3E9, 0x3E8 etc.).

[emufan]

that sounds promising. I cannot decipher them, but those 0x3E9, 0x3E8, 0x3E7 ...
are all typical amiga hunk types.
I could imagine, those 0x4E9 were introduced with warpos, but still sort of standard amiga hunk type.

but how to "set to GCC mode". is it a ppc-amigaos-gcc option?
and target "Amiga Classic OS" ? I thought warpup is Classic Amiga, with a ppc extension/co-processor.

StormC4 comes with an IDE with a lot of menus with options. You can choose between GCC and StormC3 mode. Amiga Classic OS/PPC Native/something i forgot.

So yes, warpup is in this case Classic Amiga with a ppc extension.

ah, allright, I forgot the IDE. makes sense now

Any recommended version of SDL_Mixer? 1.2.5? Or any version of libOGG and libVorbis?

1.2.4 compiled and Playwav works, actually worked with one of the Wavs I made out of Amidi from HOMM2 midis 10+MB at 16-bit audio.

Trying to figure out why Playmus doesn't work. Pointed it at my Timidity patches which I can see it reading all the .cfgs but then just looks for
MIX_EFFECTSMAXSPEED
MUSIC_CMD

Mods play I guess midi isn't supported by this test program. No idea what's going on.

[grelbfarlk]

Will get back to SDL_mixer midi stuff later. Hedeon got Truetype working so SDL_ttf works.

Anyone have an SDL game suggestion that should work with a simple compile -lSDL?

And midi too.

[grelbfarlk]

Xrick works.

[grelbfarlk]

jetpac "works".

Working on compiling an application and have some unrecognized symbols:
snprintf
vsnprintf
rmdir
ftruncate
environ
dirname

Which are part of glibc and not in the version we have already.
Using one of the libnix compiles the community has developed I was able to piece together snprintf and vsnprintf and link in the compile which no longer complains. But the rest don't seem to work or are not in libnix. Any general advice on how to compile glibc 2.2.5 for an unknown architecture?

I would continue with the available libnix ports but they don't seem to have ftruncate.

[grelbfarlk]

If anyone has an idea how to contact Jarmo Laakkonen we'd really like to get a hold of the libnix_wos source to update it with the missing functions.

We have a pretty neat program we're trying to get running which has the missing functions:
readdir
rmdir
ftruncate
environ
snprintf
vsnprintf

With some duct tape and hammering and compiling random sources leaves us with:
rmdir and ftruncate that I can't find something that will compile. Halp?

[grelbfarlk]

I managed to compile the missing functions and actually got something produced. Dosbox 0.72 for WarpOS is now in bet- ALPHA. Thanks guys for all the help.

Dude! That's awesome. This is something I was hoping to take a crack at one of these days, if you recall

I do remember, and I'm still waiting for someone more capable to do it!

[grelbfarlk]

Exult worked, getting the linking order took a bit of screwing around to get right it was this:
-lprints -lSDL_mixer -lvorbisfile -lvorbis -logg -lSDL_wos

Bermuda Syndrome worked with the defaults in the makefile.

i try to build it for 68k, but there is no vorbis and ogg for 68k.
did you build them for ppc on your own?

can you attach your Makefile? did it build with SDL 1.2.x ?

Yeah I built libogg and libvorbis for WarpOS, wasn't much to it really, I think vorbis had some or one missing function. Yes with SDL 1.2.x.

Should be really easy to build for 68k. I just used the OS4 makefile from OS4Depot, adding some WarpOS compiler flags and playing with the linking order. Don't know if it's a faux pas to link directly to the lha:
http://os4depot.net/index.php?functi...at=game/action

Working on a couple new things, maybe they're possible for me or not. But this week I had to get bzip2 and LUA for them and a couple other libraries-getting hard to keep track my lib directory is getting pretty bloated.

List so far of what we have:
SDL 1.2.6
SDL Mixer
SDL Image
SDL Sound
TTF
Freetype
libzip
libpng
libjpeg
libsmpeg
libvorbis
libogg
liblua
libbzip2
