Flare enough

@walkero

This is not pretty but worked in 2024.

EDIT:

As I checked six months ago, Flare 1.14 worked on QEMU M1 Peg2.
Compiling with cmake cross compiling clib4
This compilation was done to work well under QEMU emulation.
Someone needs to do it for the real hardware profile.
It should work.

@smarkusg
That's an interesting topic to discuss. For not derailing this thread, would you like to open another and discuss it there?

@walkero
I have corrected the entry.

If you need a tester, I'm available. And great that you accepted! 😉

@Maijestro
I sent it - it works for me.
I also checked it on Qemu passthrough Asus Radeon HD 7750 with acceleration settings - it works for me too.
I hope it will work for you as well.

ps
Once everything is working, you can go ahead and share the files without even mentioning who created them.

Thank you for making it available for me to test

However, when I run Flare, I get a GR and I don't know why this happens. The GR can be ignored and then the game starts. I played for about 5-6 minutes until my system froze completely.

I am attaching the GR log in case it might be useful.

@Maijestro
It is possible that something is not working because this version of Flare has forced compositing modes and a few other changes to work under QEMU and sm502.
I remember playing it for a few hours and the system was working.
Yesterday, I just launched it under Qemu passthrough Asus Radeon HD 7750 and ran it for a while.
It launched normally....

In that case, the topic of the new version of Flare is open so that it works on all machines.

You are not to blame, with some ports the errors do not occur under Qemu Peg/A1XE and even on X1000, but sometimes problems can occur on Sam460 or X5000. Of course you could not reproduce it because you are not using any of these hardware.

Steffen Häuser explained it like this in another thread.


Zitat:

"If the author of the port has a Peg2 or x1000, he can't KNOW about the problem, because there are no alignment problems with them. In other words, the author is not to blame here (except perhaps for the fact that he did not use enough different hardware during the beta test ;---) ). With AmigaOS4 ports it is ALWAYS important to test on devices that are neither x1000 nor QEmu nor Peg2 in order to rule out alignment problems."

I also tested it under Qemu/Peg2 with Wazp3d, and yes, the GR could not be reproduced here.

@Maijestro
QEMU does emulate sam460ex too including the different BookE CPU so it could be tested on that but I'm not sure every detail of this system is emulated but it could be improved if that helps testing. Also in AmigaOS most binaries are the same between machines and the kernel handles differences between CPUs in most cases (e.g. A1222 kernel emulates missing FPU) so I'm not sure what alignment issue is referred to here. One difference is that on some systems (at least sam460ex, X5000 and A1222) the kernel uses the SoC's DMA engine so maybe that has some required alignment on real machine that is not there on other systems or QEMU. If this is the case it could be checked in the 460EX DMA engine emulation in QEMU and produce a guest_errors warning for it to help developers but I'm not sure what the real issue is here. In any case it should not crash (unless the app uses DMA itself) as the kernel could also fix it up and provide a warning for such unaligned DMA requests but I don't know how this is handled in AmigaOS and I may be completely wrong about what is causing the problem.

@Maijestro

What I wrote here in the part you quoted does NOT apply to this GR.
According to the GR you posted it is NOT an Alignment exception but a DSI.

Did you check if your SDL2 settings are set to Compositing (as Marek wrote that his code required compositing) ?

If this does not help my suggestion would be to compile a debug version of the program to see if this gives more details of what exactly is going wrong.

Also maybe compare if the system where it runs and the system where it doesn't use the same version of clib4.library (myselves I did not do much with clib4, I usually use newlib).

@TheMagicSN

I have SDL Prefs set to Compositing. I also copied the included clib4 library to SYS:Libs/. None of this helped.

I would like to find out why there are no problems under Qemu Peg/A1Xe or even with qemu passthrough gpu. This could be useful for developers.

First, it will be tested on a similar real machine to confirm that my configuration here is not the problem.
