I tested the real case, replacing CONSTRUCTOR_FUNCTION tokens with __attribute__ notation. This is so bad. There are multiple shared objects, and only a selection (random?) of the constructor functions are called. This is utterly incomprehensible.

I opened a new ticket for tracking purposes.

It gets worse. Static constructors and destructors no longer work with the latest adtools. This is strange, since the exact same code + elf.library worked fine a few releases ago.

Do you mean in context of shared objects? I have had some headaches with library constructor calls.

I tested your example and it seems to work as long as I don't declare any __attribute__((constructor)) stuff. If I do, then only one constructor is called. I don't understand the issue at all :(

My examples:


// library code

#include <proto/exec.h>

#include <stdio.h>



#define CONSTRUCTOR_FUNCTION0(AFUNC) \

namespace { \

static const struct AFUNC ## _ctor_class_ { \

inline AFUNC ## _ctor_class_() { AFUNC(); } \

} AFUNC ## _ctor_instance_; \

}



#define CONSTRUCTOR_FUNCTION(AFUNC) CONSTRUCTOR_FUNCTION0(AFUNC)



void foo()

{

    printf("%s\n", __func__);

}



void bar()

{

    printf("%s\n", __func__);

}



CONSTRUCTOR_FUNCTION(foo);

CONSTRUCTOR_FUNCTION(bar);



#if 1

void __attribute__((constructor(1000))) ctor()

{

    printf("%s\n", __func__);

}



void  __attribute__((destructor(1000))) dtor()

{

    printf("%s\n", __func__);

}



void __attribute__((constructor(2000))) ctor2()

{

    printf("%s\n", __func__);

}



void  __attribute__((destructor(2000))) dtor2()

{

    printf("%s\n", __func__);

}

#endif



int f(int x)

{

    printf("%s %d\n", __func__, x);



    return x;

}



// main



#include <stdio.h>



int f(int);



int main()

{

    int result = f(123);



    printf("%s result %d\n", __func__, result);



    return 0;

}



// makefile



CC=g++



all:

    $(CC) -o lib.o -c lib.c -fPIC

    $(CC) -o libf.so lib.o -shared

    ar cruv  libf.a lib.o

    ranlib libf.a 

    $(CC) -o test_dyn main.c -use-dynld -L. -lf -athread=native 

    $(CC) -o test_static main.c -L. -lf -athread=native

Results (GCC 11.2):

Quote:

constructor> test_static
ctor
ctor2
foo
bar
f 123
main result 123
dtor2
dtor

So far so good.

constructor> test_dyn
ctor
f 123
main result 123
dtor2
dtor

WTF: ctor2, foo and bar calls missing?

Then I disable __attribute__ stuff and things get more consistent:

constructor> test_dyn
foo
bar
f 123
main result 123

constructor> test_static
foo
bar
f 123
main result 123

I didn't see function similar to SDL_VideoModeOK either.

Scaling seems to exist for surface (https://wiki.libsdl.org/SDL2/SDL_BlitScaled) but if you want to accelerate it, you should create a renderer and a texture, and copy surface to texture each frame.

SDL_WINDOW_FULLSCREEN_DESKTOP is not working properly (it was never supported so far) but I started to test it yesterday. Need some debugging.

If app doesn't call SDL_Quit(), then our thread subsystem will not be cleaned up. Maybe I should try again constructor/destructor approach which might solve this implicitly.

I don't know. I haven't studied the compatibility topic. AFAIK SDL3 API is not stable yet, so it's not for end users. Maybe in 3.2.0?

Sources are in the same dir ( http://capehill.kapsi.fi/quake2/ ). Port is 14 years old, so I don't remember much. Maybe I added just a stack cookie. IIRC Hyperion SW renderer port existed at that time.

@Raziel

Your new branch is based on the one you were before, master. "sgit log" shows you the commits done.

If you have non committed changes before checkout, be careful because branch switching using sgit is destructive (if I remember correctly), so you could lose changes.

64*64 is too small. There is a limit that window must be at least 100*100 for iconification gadget to be added. I don't know what is the actual limit in the OS but if window is too small, it doesn't work.

Syntax seems correct to me.

1) Are you able to fetch from origin?
2) Are you pushing from repo's root level (some sgit commands are picky about directory: not sure about push)
3) Is your local branch called "patch-1"?

GetAttr issue happens because program tries to query non-existing ClickTab gadget (in case there is no editor). I guess this was more broken before 1.17 (shader loading failed?) but it seems error print was not removed earlier.

I will add a workaround to avoid this error log.

Re: ScummVM and AmigaOS4.1 F.E.

@Raziel

I could not get Grim demo working on ScummVM 2.6.0. It cannot load grim_background.vertex shader. This file seems to be in extras/shaders directory. Should this demo work?

It seems that OGLES2 results are missing in your log because ScummVM (or SDL2) didn't unload GL library for some reason. This works with test/testgles2 so it could be something ScummVM-specific. SDL2 is supposed to unload GL library when destroying the window.

Could you try this:

1) start glSnoop with params PROFILE GUI
2) finish profiling from gui
3) start ScummVM
4) start profiling again
5) finally stop profiling - now you should have both OGLES2/Nova results from the correct time frame

Thanks for the log sample, but based on that profiling period was very short (< 1 second) and there were very few draw calls. I could see 1 Clear and 2 DrawArrays, so almost nothing was renderered during this capture. Also OGLES2 results were not included.

Also calls of TexUpdateSubImage were expensive, average shows 13 ms so that's almost the budget for one frame at 60 FPS (~16 ms).

EDIT: strange, now I see that there are multiple short-lived context creations. Maybe ScummVM is creating the GL context many times. I'm not sure which of the results is relevant, if any.

Does this happen with Grim Fandango demo version? And did you try to remove that suspected frame cap?

Could you also test with Hieronymus? http://os4depot.net/?function=showfil ... ment/debug/hieronymus.lha

SDL2 settings should not impact OpenGL(ES2) applications, they are for SDL_Renderer subsystem (which has multiple driver backends from software to DirectX to OpenGL to Vulkan etc).

I don't think your graphics card is supported by Warp3D, AFAIK it's only for Southern Islands series (until NovaBridge).

1) You need a supported graphics card
2) Or you need Quake2 from Hyperion (it should support SW rendering)
3) Or maybe you can use Wazp3D

I wish OS4Depot had some kind of tagging/keyword system. For example, if you search for "ogles2", there is about 2 hits currently.
