SDL

[MBeijer]

I noticed that you finally added the SDK SDL. I'm curious of how the SDK install works.

The repository https://github.com/AmigaPorts/libSDL12 has SDL 1.2.15, reworked for AmigaOS3.x with a bunch of bug-fixes over 1.2.6, like fullscreen finally works. As well as AMMX extras working for Vampire cards to get some extra speed with the blitter.

The functioning makefile in this repository is Makefile.bax. The prefix is wrong but the rest should be correct.

The Vampire specific functions are defined in an vasm assembler file, that is compiled with VASM and then included in the gcc linker.

The Apollo/Vampire specifics seem to be in here: https://github.com/AmigaPorts/libSDL12/tree/master/video/apollo

The Apollo/Vampire specifics are designed to only be used if the Apollo based CPU is identified. So it will work on 020, 030, 040 and 060 just as well!

I think Makefile.bax is pretty self explanatory! =)

I need to know how I could implement this in the SDK install process, so we can leave the bug-ridden SDL 1.2.6 from Aminet behind, once and for all!

[bebbo]

You have to make a decision: a) provide a sdk file use this to install precompile binaries b) provide a Makefile snippet this gets added to the Makefile itself. Maybe we find a comfortable way to provide separate Makefiles for such a purpose.

A simple starting point is the integration of libdebug:

# =================================================
# libdebug
# =================================================
CONFIG_LIBDEBUG = --prefix=$(PREFIX) --target=m68k-amigaos --host=m68k-amigaos 

libdebug: build/libdebug/_done

build/libdebug/_done: build/libdebug/Makefile
    cd build/libdebug && $(MAKE)
    cp build/libdebug/libdebug.a $(PREFIX)/m68k-amigaos/lib/
    echo "done" >build/libdebug/_done

build/libdebug/Makefile: build/libnix/Makefile projects/libdebug/configure $(shell find 2>/dev/null projects/libdebug -not \( -path projects/libdebug/.git -prune \) -type f)
    mkdir -p build/libdebug
    cd build/libdebug && $(A) $(PWD)/projects/libdebug/configure $(CONFIG_LIBDEBUG)

projects/libdebug/configure:
    @mkdir -p projects
    cd projects &&  git clone -b master --depth 4 https://github.com/bebbo/libdebug

projects/libdebug/configure is a file which always exists after cloning.

Here is a configure command invoked to create the Makefile in the build folder. Otherwise I use rsync to copy all files.

Then I invoke the makefile and install the files.

[bebbo]

first try:

CONFIG_LIBSDL12 = PREFX=$(PREFIX) PREF=$(PREFIX)  

libSDL12: build/libSDL12/_done

build/libSDL12/_done: build/libSDL12/Makefile.bax
    cd build/libSDL12 && $(MAKE) -f Makefile.bax $(CONFIG_LIBSDL12)
    cp build/libSDL12/libsdl.a $(PREFIX)/m68k-amigaos/lib/
    echo "done" >build/libsdl/_done

build/libSDL12/Makefile.bax: build/libnix/Makefile projects/libSDL12/Makefile.bax $(shell find 2>/dev/null projects/libSDL12 -not \( -path projects/libSDL12/.git -prune \) -type f)
    mkdir -p build/libSDL12
    rsync -a projects/libSDL12/* build/libSDL12 

projects/libSDL12/Makefile.bax:
    @mkdir -p projects
    cd projects &&  git clone -b master --depth 4  https://github.com/AmigaPorts/libSDL12

[MBeijer]

I have asked Henryk Richter (author of the libSDL12 repo) to join us in this issue with his input. So please leave this open. :)

[MBeijer]

inttypes.h is always an issue for me with your toolchain, which is why I have added my own inttypes.h file in /opt/m68k-amigaos/include:

[MBeijer]

I believe I've mentioned this before, but been told I've done something wrong. Eventually I just added the file myself.

It's required for me to compile MilkyTracker as well.

[MBeijer]

I don't know how much of this file is actually needed.

[bebbo]

I'll add it to ixemul --> ends up in sys-includes

next:

ideo/amigaos/SDL_cgxvideo.c:40:41: fatal error: cybergraphics/cybergraphics.h: No such file or directory
 #include <cybergraphics/cybergraphics.h>

it depends on the cgx.sdk

[bebbo]

but there it is CGraphX/C/Include/cybergraphx/cybergraphics.h

[MBeijer]

Yeah, for some reason the include path for cybergraphics has changed between cybergraphx and cybergraphics between generations. While one is still used in MorphOS, another is used in your toolchain. And depending on source I've been working with it's been switched around. Pretty stupid. How does the toolchain handle symlinks?

[bebbo]

if symlinks exists, they are used :-) I could add symlink creation to sdk install

[bebbo]

next one:

-I/opt/amiga/os-include

should be /$(PREFX)/m68k-amigaos/sys-include

no?

[MBeijer]

yup, it differs on older GCC toolchains, especially if you use the old gg toolchain in Workbench

[MBeijer]

I added you to the SDL team on AmigaPorts. Feel free to make changes to the libSDL12 repo.

[bebbo]

I will look tomorrow - I pushed what I already did.

[bebbo]

make libSDL12 is built now.

But the headers are currently not installed, because I don't like the fact that all headers are duplicated. I'd prefer having the SDL headers in the SDL folder.

[MBeijer]

Yeah, I don't know why that is like that. I have to ask Henryk about this.

[HenrykRichter]

I knew that this thing would be going to haunt me. Yes, you both are absolutely right. There are redundant files in this particular Amiga SDL port. I didn't find time and motivation to clean the source up, as of yet.

FWIW, I've deleted the superfluous includes and kept only the SDL subdirectory. The lib builds just as fine. As Bebbo pointed out, inttypes.h is not really necessary to build SDL itself. Hence, it is disabled now in SDL_config_amigaos.h.

Hope it helps along a little.

[MBeijer]

Thanks for that! :)

Bebbo: One request I have is that I'd like it if the SDL includes ends up in /opt/m68k-amigaos/include/ SDL/ rather than /opt/m68k-amigaos/m68k-amigaos/include/ so system specific includes doesn't get mixed in with ported libs and such.

[bebbo]

now the SDL and GL folders are copied.

[MBeijer]

As a side-note, I intend to apply the fixes from the libSDL12 repo to the AmigaPorts/SDL repo. When it's time to switch I'll let you know. Until then libSDL12 serves its purpose.

[MBeijer]

Awesome, thank you! :) 👍

[MBeijer]

Make-script fails at libSDL12:

make: *** [Makefile:623: build/libSDL12/_done] Error 127

[MBeijer]

Simply moving the first " from "CFLAGS= to CFLAGS=" fixes this.

[bebbo]

... happens :-)

[bebbo]

what's left to do here?

[MBeijer]

Nothing until we're/I'm done merging the libSDL12 repo into the AmigaPorts/SDL/SDL-1.2 branch, which is a lot of manual work!

[bebbo]

reopened if necessary
