SDL2

@broadblues

Some tests don't even rely on SDL cleanup. They rely on OS cleanups. Sigh.

I hope nobody tries to learn SDL from its "test" code :)

@Capehill

I suppose that Compositing should produce better results. However only a test can give us some responses

Fixed SDL_Image configure (thanks to Mtchael T. Suggestions)
Fixed the SDL_Image makefile.
SDL_Image compiled.

Still few errors in loadimage.c sample file.

Ported SDL_GFX2 too

very cool effects possible.

Demo makers could play with those effects a little.

@AmigaBlitter

What, no teaser images?

@Capehill

Sorry for the bad quality

for the third image sgrab can't catch the animated image, but the effect still nice

@thread

Please don't forget to danate to the developers for the time they spend to the project.

A big thank to capehill.

Capehill for president

@AmigaBlitter

Thanks for the support and testing.

A new issue popped up when testing accelerated (OpenGL) renderer. It cannot open all necessary functions so it fails. glBlendFuncSeparate is the first failure. I am not sure at the moment what else might be missing - list is here (used functions are the ones with SDL_PROC macro):

https://sourceforge.net/p/sdl2-amigaos ... nder/opengl/SDL_glfuncs.h

@Capehill
There's no such function in MiniGL, because Warp3D doesn't support setting the color and alpha blending separately.

@Capehill

You're welcome.

Ported SDL2_TTF and SDL2_Mixer meanwhile.

Have to test asap

...found an error for the mixer

I'm having trouble building SDL2 (svn r63). When linking the .so:

Any ideas? I'm using gcc 5.3.0 in Cygwin, and base/newlib/clib from SDK 53.30

I'll try again with an earlier compiler (just stock non-cross SDK) later on.

@MickJT

Try with G++ incited of GCC
or try with -lauto flag.

Double post... :-/

@MickJT

What was your configure line?

With GCC4.something, I can't build .so without modifying the makefile. I remove -no-undefined for libtool _and_ gcc and then I get the lib. I don't know why these switches exist in buildsystem, but also SDL1 has -no-undefined switch for libtool at least:

https://github.com/adtools/os4sdl/blob/master/Makefile#L51

You can try that, but I'm not really familiar with this topic. There is a ticket open on SDL2 project page regarding .so.

@MickJT

I had some problem with the 5.3. The configure freeze the system.

Reverted back to 4.9.1

@AmigaBlitter

Try bigger stack + serial cable :)

@BSzili

Yeah, luckily, glBlendFuncSeparate seems to be the only missing function. Here are the SDL blenders:

https://wiki.libsdl.org/SDL_SetTextureBlendMode

Looks like we can use just glBlendMode for "none" and "blend", while "add" and "mod" can be a little bit funky.

EDIT: forgot the issue of NPOT textures. This can be a showstopper for MiniGL renderer.
EDIT2: damn, it's good to be wrong. Looks like internally SDL2 uses POT textures.

I removed -no-undefined in a few places in the Makefile, and was able to build the .so and .a

I then compiled SDL2_image. Both the static and shared versions worked (note that there are source code changes that are needed to build a functional .so of SDL_image).

I tested showimage on a .pcx image, and set the stack to 1000000. It freezes shortly after displaying the image, and the window cannot close.

Anyway, good to see progress :)

@MickJT

If I had serial log, I might be able to help. At the moment I have hands full with the core lib so I'm not going to compile satellite libs this week...


Source code of showimage doesn't look buggy. It relies on implicit initialization and quitting of video system so it's a bit "lazy" though. But at least it calls SDL_Quit.

@MickJT

I've compiled the SDL2_Image previously and worked fine. Haven't tried a PCX, tho.

SDL2_TTF compiled too.
SDL2_Mixer compiled removing the libmodplug option atm. It causes the SDL2_mixer compilation failure, cause it come from a previously wrong compilation (from SDL 1.2
