WarpOS version of SDL

Does anyone know of or have an SDL link library for WarpOS for GCC 2.95.3?
I have found a StormC version and what I think is a SAS/C version but nothing for GCC or the source for it.

http://aminet.net/package/dev/misc/AmigaSDLstorm4

I am aware of the WarpSDL.library from OnyxSoft.

http://www.onyxsoft.se/warpsdl.html

But no source is available and I'm not smart enough to convert all those to openlibrary calls even if all of the functions are available.

Just as an experiment I tried compiling the old OS4 version of ScummVM 0.11.1 which fails on the OS FS stuff and SDL, but 589 other objects were compiled.

So I found an older version which includes a WarpOS version and managed to get it all to compile except for the PPC Tasks and Threads part. These didn't compile.

Prerequisite `SDL_syssem.wo' of target `libSDL_wos.a' does not exist.
Prerequisite `SDL_systhread.wo' of target `libSDL_wos.a' does not exist.
Prerequisite `SDL_thread.wo' of target `libSDL_wos.a' does not exist.

Which it seems to be complaining about:

};
In Semawhoresppc.h:

struct SignalSemaphorePPC {
struct SignalSemaphore ssppc_SS;
APTR ssppc_reserved; /* private */
UWORD ssppc_lock; /* private */
};

*Update* turns out I wasn't including the right file.

Done, I mean if it works.

the .lib do indeed look like sas/c compatible stuff. fileheader on those gcc made .a look different.

some moons ago I was building successfully sdl with SDL-AmigaSrc.lha.
using Makefile.cross. IIRC i only enabled "-DNO_AMIGADEBUG".

it was build for 68k, not sure about ppc. cannot remember which compiler, maybe
2.95 gcc or the one from AmiDevCpp ( gcc 3.5) - on a win7 box.

I have 3 gcc crosscompiler on my winbox. some sources compile with 2.95,
others with 6.x only. most compatible gcc comes with AmiDevCPP - gcc3.4.

you can use AmiDevCpp's gcc from a dos command shell.

open a cmd, cd to AmiDevCpp/bin and start a bash. basicaly it is a cygwin environment.
after starting bash.exe I only add path:
Code:
export PATH=/cygdrive/d/AmiDevCpp/usr/local/amiga/bin:/cygdrive/d/AmiDevCpp/bin:$PATH
this way you can use ./configure scripts, which is impossible with the AmiDevCpp gui version.
it does also have ppc-amigaos-gcc-4.2.0.exe incl the compiler tools for that.

#1) sometimes it is usefull to use CFLAGS like -std=c99 .
not sure if the following options apply to warpos / ppc aswell:
gcc with -noixemul or -mcrt=clib2 or -mcrt=nix13 or without any of them, can make big difference.

#2) and offten you try to find some errors in the source code, but the troublemaker is the incompatibe compiler ...

Very interesting Emufan, I didn't know there was a cross compiler for WarpOS in Amidevcpp. I'll look into that.

Here's the lib if anyone wants to give it a try making it do something. It's compiled in gcc 2.95.3.

Version 1.2.6 (really old).

congrats

1.2.6 is old, but good enough for the amiga. I'm using them for the sdl emulators.
btw. I'm using the includes by Novacoder - SDL_AGA.
take a look at the SDL_config* files. maybe usefull somehow.

now if I could only figure out how to use ppc-amigaos-g++ to actually link to the thing properly, I might could meet Cowcat's challenge of opening a simple intution window.

hmm, link with libSDl.a ? something like this:
g++ example.cpp libSDl.a -o example.exe

btw: some good point of AmiDevCpp, it does have the ability to produce binaries,
which uses ixemul.library. this was of great use, when it came to source code with path/directory/filehandling.
this happens if you do not use any of the 3 CFLAGs i wrote above.

Are you sure that the cross compiler for AmiDevCPP works with Warpos? The ppc-amigaos-gcc stuff seems to just be for OS4.

I cannot say for sure, never did any ppc stuff, just saw the *ppc* binary

#1) in the gui i can only find new project for amiga-68k and amiga-OS4. my bad :/

Pretty sure the lib is a failure. No matter what I try to link it with I get stuff like:

As I explained in other thread, the gcc-warpos stuff doesn't work now AFAIK. I asume the compiled gcc binaries/libraries where done with old warpos includes. I tried to correct some of those (specially some function calls inlines that needed more parameters/registers), but no luck for now.

But I don't know any binary done by this gcc version to compare for example with an old or new warpos kernel.

try the nm command and look if those function are in the libSDL.a:
Code:
$ m68k-amigaos-nm.exe -l libSDL.a | grep SDL_Flip
0000089c T _SDL_Flip
and ensure you have libSDl.a in last position in the object link order.

with the m68k cross compilers those issue may be fixed by using libauto, -lAuto , -lauto.
-noixemul is ment to take care of those aswell.
not all compilers support those commands, or have their functionality, it seems.

I didn't read all of this thread, but your PPC-gcc seems to be configured for ELF V.4-ABI, not WarpOS PowerOpen-ABI. In ELF the compiler creates (and refers to) symbols without leading underscore. The library, on the other hand, looks like a real WarpOS library with underscores.

it's about grelbfarlk attemp to create a libsSDl for warpOS.
i only gave some hint on how I did things with building m68k version of libSDL.

but any help is welcome

#1) your vbcc does have support for warpos, does build wos binaries?

#2) zoned: stormc4_gnu_sources.part1.rar stormc4_gnu_sources.part2.rar
which should have wos support?
there are some bin-utils binaries included. not sure if 68k or wos.
project files for StormC4 to rebuild them seems to be there too, also some Makefies.

is StormC4 still being sold? I can find StormC3 only. anyone with StormC4 installer?

#3) tested the bin-utils from stromc archive, no ppc support it seems:
Code:
3.SYS:binutils> nm-new -l ram:libSDL_wos.a 
nm-new: SDL_error.wo: File format not recognized
nm-new: SDL_fatal.wo: File format not recognized
nm-new: SDL_yuv.wo: File format not recognized
nm-new: SDL_yuv_sw.wo: File format not recognized
nm-new: SDL_yuv_mmx.wo: File format not recognized
...
the Undefined Symbol are not available. ?

Yeah it does, actually Hedeon suggested trying VBCC to build some of these objects when GCC wasn't giving me any useful errors. That's what lead me to find that it was puking on the includes.

nm says: For SDL_Flip
000012d8 T SDL_Flip
U SDL_FormatChanged (null):0
U SDL_FreeFormat (null):0
U SDL_FreeSurface (null):0

And SDL_Init
0000015c T SDL_Init

I get the same for the 68k version. with different offset and leading "_".
hmm, you did link with the correct version: g++ ... libSDL_wos.a
dont use -lSDL to ensure you link with the correct one.

I use -lSDL_wos or -LlibSDL_wos.a same difference. -lauto and -lAuto are not found.

If I do:
ppc-amigaos-g++ -warpup -lSDL_wos sdltest2.cpp -o sdltest801.elf
