I can't say right now is it a bug or feature.

But it's wrong to assume that all platform behave identically. For example, not every target support all accelerations. Some have Altivec, for example.

Yeah indeed.. Through that test code works not only on win32, but also on linux and macos, only fail like that on amigaos4.

Anyway, even if we have SDL_PREALLOC flag set for us as aos4 only thing, it still shouldn't skip the calling of resizewindow in the sdl's code when SDL_OPENGL | SDL_RESIZABLE flags set together with SDL_PREALLOC ?

@Capehill
Have another question, related to SDL1/SDL2 differences.

For SDL1 to get list of screenmodes we use something like:

SDL_ListModes();

Now, for SDL2, we use something like this (to have analogue):

SDL_GetNumDisplayModes() + SDL_GetDisplayMode()

Question now is:

For SDL1 return of screenmodes is sorted by height. For SDL2 return of screenmodes is sorted by width. I.e. when i do printf for what i have in return, then for SDL1 i have:

more_num: 0, w = 1920, h = 1200
more_num: 1, w = 1600, h = 1200
more_num: 2, w = 1920, h = 1080
more_num: 3, w = 1440, h = 900
more_num: 4, w = 1024, h = 768
more_num: 5, w = 1280, h = 720

And for SDL2:

more_num: 0, w = 1920, h = 1200
more_num: 1, w = 1920, h = 1080
more_num: 2, w = 1600, h = 1200
more_num: 3, w = 1440, h = 900
more_num: 4, w = 1280, h = 720
more_num: 5, w = 1024, h = 768

See for SDL1 order of screenmodes is sorted by height, while for SDL2 buffer of screenmodes is sorted by width.

I checked win32 version of the same code, and there SDL1 sort the output the same as in SDL2 : by width.

So, if i understand right, it is bug in SDL1 , right ?

You are correct, modes should be sorted from largest to smallest: https://www.libsdl.org/release/SDL-1.2 ... cs/html/sdllistmodes.html

In meantime created 2 bug reports we discuss there lately for SDL1, so they will be not forgotten:

1.2.15: not released I guess (?), some pending issues. There is a native makefile which you can use to build it though.

1.2.13: http://os4depot.net/index.php?functio ... ry/toolkit/sdl-newlib.lha

Hmm, ok.

But what if i have the 1.2.15 sdk installed and the 1.2.13 library?
Do .15 compiled programs work with the .13 lib?

SDL 1.2.14 and 1.2.15 seem to be mostly bugfix releases so there shouldn't be API changes: https://www.libsdl.org/release/changes-1.2.html

I guess we need to create 1.2.15 RC 1 and slowly keep fixing whatever is still broken.

Yeah current SDL1 already much better than old 1.2.13 and can be released as it already. Its not only bugs fixed by original authors, but also many amigaos4 bugs was fixed since as well (by you lately, but also in previous years by others) , also those new features (iconify, compositing, etc), code now cleaner and so on. Huge task, worth of release :)

Maybe only need to be released also as SDL2 with plain and debug libraries, so all will be same for both SDLs, as well as probabaly need to be merged with latest changes from main authors too (there was some fixes lately (like 10 days ago some buffer overflow fixed in SDL_pixel.c in both SDL2 and SDL1))

Quite a regular

I just found out why EasyRPG had no 2x zoom when started in windowed mode. The current_w and current_h fields of the SDL_VideoInfo structure wasn't filled in with the desktop resolution.

Thanks.

@All

SDL 1.2.15 RC 1 is released: https://github.com/AmigaPorts/SDL/releases/tag/v1.2.15-rc1-amigaos4

It comes with 2 test programs: "testver" to verify the installation, and "testgl" to see something on the screen.

For those who want to see some serial debug, there are libSDL_debug.a and libSDL-1.2_debug.so.

Nice, thank you

I do hve a question...if i open the "tests" directory (i have unpacked it in ram: i get a AmigaDOS requester telling me to

Please instert volume
Hibernated:
in any drive

Process: 89 "Workbench"

I didn't know that simple files could trigger AmigaDOS meessages...

EDIT: Nevermind, i had an .adf mounted earlier and it seems the system was still looking for it, although it was already unmounted from Diskimage.device

@samo79

Seems to work here, started 10 instances. Is your case reproducible?

What is the version of your MiniGL.library? Can you reproduce issue with SDL debug .so and get the traces?

@Capehill

Yes, i can reproduce it also with SDL1 debug version.
I do some test and i can say that i have atleast two kind of results when i run a second instance of that demo, or a freeze or a DSI crash and these seems happen randomly

As you may think it's probably caused by MiniGL, actually i'm using a beta version of MiniGL 2.23 (not yet publically released)

Here the library so you can test:

@samo79

Well, the crash is inside of MiniGL.library. You need to ask the person who made MiniGL 2.23 where / why it crashes. The library you provided doesn't have debug symbols.

Based on the first stack trace it seems to have happened during MGLUpdateContextTags() call. That's where SDL part points to.

If i remember correcly the version i have was the one compiled by HunoPPC for his Warp3D "GUI" project ... it should be based on an interim revision of 2.23 from the official repo, so not the very latest

I read that you are still trying to compile the very latest build now, maybe i can retry with the latest official build as soon as you release it, so eventually we can see if the bug i have on this SDL1 demo is an "official" bug or if it was just the interim version of MiniGL compiled by Huno to be blamed
