GL4ES / SDL+GL4ES / CLIB2 / Outdated NEWLIB libs and OnWards

Okay. We have pthreads now in CLIB2 and progress is being made with a C library for which we have source code access to. Who knows when extra features to newlib will happen.

For that reason, I continued on my quest to make improvements to mednafen.

Rather than the necessary hacks I needed to add to the mednafen source code to ensure successful builds against newlib, due to a great, but outdated 2004/5 version of pthreads, I wanted to link with CLIB2 instead of newlib.

It has been a success, but it required that a number of library be compiled with CLIB2. This, at least for mednafen, included "porting" libFLAC to CLIB2. It also required building GL4ES / SDL2_GL4ES with CLIB2.

What I am noticing is outdated libraries on OS4Depot that are linked against NEWLIB. Going forward, we probably always want to offer both. But, I worry that the LHA files and their original owners on OS4Depot are either inactive or will never update to include CLIB2 / newer versions on those libraries.

I wonder how we can solve that issue.

Tonight, I compiled bleeding-edge GL4ES using CLIB2 commit: 44cdcded7653ec5f3cc845b1b0e28c78f6f2b4d3 (this included the merged back pthreads branch). Before I say the following, I thank @kas1e, @capehill, @hans for all the work. But, I kind of needed to figure out how to build SDL2 + GL4ES on my own. @kas1e already has the GL4ES SDK, but it is with an older version of SDL2. I built SDL2@version 2.0.22 against CLIB2 - fine. I was then confused how to create SDL2 + GL4ES changes. Actually, it did not seem to be that complicated.

It was a matter of grabbing the Amiga SDL2 port and then applying the following patch file:

To the SDL2@released 2.0.22 branch. However, I am not sure if this is exactly correct!

The only issue I ran into was an undefined reference to:
OS4_GetWindowActiveSize

In order to get around that, I just hacked in some values for Height and Width - but I would like to get an idea of where that function went. Recall, that I am using the latest bleeding-edge GL4ES combined wth SDL2.0.22.

In any case, so far, Mednafen is running quite well with out DSI errors probably due to the bleeding-edge CLIB2 changes and the pthread support. A lot of the hacks I had to add could be removed such that the code base is a lot more closer to Mednafen version 1.29.

The points are:
- What happened to OS4_GetWindowActiveSize
- How can we all come together to ensure that CLIB2 versions of SDK/Library/Dev LHAs are available
- What about those that have uploaded versions of libraries from a few years ago that are only built with NEWLIB

Regards.

For sdl1/2 gl4es changes they easy yes, and on my github acc. I plan to update sdk soon with both clib2 and newlib versions as well and all libs too, but that can take some time and for you will be faster to apply changes yourself. I do have local builds of gl4es and sdls-gl4es for clib2 if need it.

As for os4depot stuff, if archive not mantained, you can replace it (it handled by os4depot admins). Especially if it was configure and make only. If it differs too much, with amiga specific changes in original archive, then you put old version inside of your archive or create different name for your upload.

Some years ago both clib2 and newlib versions were done offten by devs, but then when newlib progress and clib2 not, ppls start to ditch clib2, but now when afxgroup improve clib2 much and in end opensource clib2 is much better to work with in compare with newlib (fixes of which take years to be released) its again mean clib2 versions will happen too.

Remember at moment you can't use shared objects because you have to patch ad tools or try to use specs file included on github.

Well, the GetWindowActiveSize was removed in a much later version. So that explains it. Just a synchronisation issue between non-exact dates.

Can live with that for now, and just apply some code changes.

===

Let me be more clear. It is the fact that I applied the GL4ES additions patch from exactly: https://github.com/kas1e/SDL2_GL4ES/co ... 8b63e66ace2ebe5dae6e8288d (this patch was for an older version of SDL, and the changes - themselves, have probably moved on) to the 2.0.22 SDL release code.

Thankfully, not too much change, so it was not really a problem.

Can you upload clib2 version of libSDL_gl4es libSDL2_gl4es ?

I was able to compile clib2 libgl4es, but not libSDL clib2 versions

I do compile SDL2/newlib version now easy by downloading latest irrlicht code from my github, and changing as i say in include/IrrCompileConfig.h that:

#define _IRR_COMPILE_WITH_SDL_DEVICE_


on that:

#undef _IRR_COMPILE_WITH_SDL_DEVICE_
#define _IRR_COMPILE_WITH_SDL2_DEVICE_


Then just :

cd source/Irrlicht
make -f Makefile.amigaos4 NDEBUG=1 -j4


And there is:

$ ls -la  ../../lib/AmigaOS4
total 11476
drwxr-xr-x+ 1 user Отсутствует        0 Sep  6 06:43 .
drwxr-xr-x+ 1 user Отсутствует        0 Sep  6 06:43 ..
-rw-r--r--  1 user Отсутствует 11750592 Sep  6 06:43 libIrrlicht.a



So it did compiles sure for SDL2 as well. Maybe in too new SDL2 something were changed ? What errors do you have ?

Quote:

Clib2 / SDL1 compile, I get this error SDL_putenv()


You should't because include/SDL/SDL_stdinc.h have this:

#ifdef HAVE_PUTENV
#define SDL_putenv    putenv
#else
extern DECLSPEC int SDLCALL SDL_putenv(const char *variable);
#endif



Quote:

I managed to compile with commenting SDL_putenv.

I hope this is the correct way...


This line is 100% necessary or you will have black screen when will use opengl apps.

I do try to rebuild for SDL1/clib2 now as well, and it also did compiles fine, without undefs to SDL_putenv, but with issues with my own swprintf.cpp which do use _REENT stuff , which can't be added to clib2 for now, only when it will be clib2.library. And this swprintf already implemented in clib2, so need commenting out.

If you didn't have this issue, but instead have issue with SDL_putenv() then something wrong happens on your side and maybe you mix again newlib/clib2 builds. Very possible that you didn't add -mcrt=clib2 everywhere (as there and gcc and g++ used in irrlicht).

Can you share your irrlicht clib2 so that I can compare ?



Give me few hours, i will rebuild everything with gcc11.3.0 and all latest stuff.

While building stuff, found that there indeed issue with SDL_putenv with SDL1 when build for new clib2 and g++. But in end, SDL_putenv is simple redefine to putenv(), so this simple test case reproduce issue:

#include <stdlib.h>

char env[] = "asdfasdfas";

int main()
{
putenv(env);
}


And then:
ppc-amigaos-gcc -mcrt=newlib test.c - compiles fine, warning less
ppc-amigaos-g++ -mcrt=newlib test.c - compiles fine, warning less

ppc-amigaos-gcc -mcrt=clib2 test.c - compiles fine, but do bring warning
ppc-amigaos-g++ -mcrt=clib2 test.c - not compiles, and bring error.

But on GCC 8.3.0 + older clib2 (afxgroup's one, just not the latest) it surely works before.

Created BZ on afxgroup's page: https://github.com/afxgroup/clib2/issues/68

Can you test plz this (i not at home so can't test myself) : https://kas1e.mikendezign.com/a/irrlicht_quaketest_sdl1.zip

But just unpacking, go to bin/amigaos4/ directory and run test case (and when run, chooice opengl in the shell).

If it works, then at least gl4es itself, sdl1_gl4es and irrlicht for clib2 is working with all latest stuff , so i can then next made SDL2 version of irrlicht and sdl2_gl4es as well

While i at it, there is how reduntant OS4_GetWindowActiveSize() replaced: https://github.com/AmigaPorts/SDL-2.0/ ... bb614248a002323706dac3997

Probabaly you already doing it like this as well, but just in case, all you need to do is in replace

glViewport(0, 0, width, height);


on

glViewport(0, 0, window->w, window->h);


and remove at top of function reduntant declarations and os4_getwindowactivesize() calling

Both versions are working however with SDL1 version it is not possible to quit the test program with ESC key

SDL2 version you can quit whenever you wish.

What about FPS ? (top of the window), the same more or less ?

in SDL1 it's "alt+f4" for close, do not remember why so, probabaly just forgotten "esc", need to add if so.

So, that mean that SDL2 compiles and works fine, just with the change i quoted above.

This also mean all fine, and there are all clib2 stuff : all compiled over gcc 11.3.0. Everything of latest versions from sources (irrlicht from my page, gl4es from ptitseb's one, sdl1/sdl2 from capehill's latest ones), and all build over clib2 beta-07 from Andrea:

@rjd324
Do you need all this latest stuff for newlib also ? Or you already deal with everything yourself ?

Hey @kas1e

I dealt with it. But it is really important for us to make progress that there is a central location. If you can update your gl4es SDK with both SDL and SDL2 that would be great.

Don't understand what are/do those files in achive you posted (sdl1/sdl2).
Do I run them alone?
Or with quake (1, 2?!?!??) datafiles?
or with yout irrlitch engine data (os4depot)?

sorry for being so dumb ¿:-/


EDIT: ok runnign frrom shell (stack 1000000) both work ok.
EDIT2: got ~33fps (RX550, PowerPrefs set to dynamic & high), using OpenGL 1.5 driver (a).
EDIT3: SDL1 can move with cursor keys, but with SDL2 they don't work, just mouse for "moving" view.

Something VERY wrong on your side. It should be 260 FPS and not 33 (at least on my side it is). PowerPrefs should be not dynamic, but HIGH.

You probablay on running of examples choose software renderer by mistake, or something of that sort, you should choose exactly "OpenGL" driver (check for correct letter twice). I.e. you run example, and when it ask for driver, hit "a", not "d" or "e". Because 33 FPS it is kind of what you have with software rendering and/or burning video driver (which also software rendering, just a bit heavier).
