[FPC 3.2.4, Windows] PTC unit broken?

[Fred vS]

@Fred vS
So what am I using? Ptc on windows 11. Only difference is I am using FPC trunk. And I checked the examples.

Hum, I just tested with main (trunk of today) of fpc 3.3.1 64 bit on Windows 11 version 25H2 (OS build 26200.8117) and the \fpc-main\packages\ptc\examples\flower.pp demo:

Code: Pascal  [Select][+][-]

1.  ./flower.exe
2. An unhandled exception occurred at $000000010000965B:

And with fpc main (trunk of today) 3.3.1 32 bit:

I see this topic and I tried with stable release (4.6 / 3.2.2) and Windows 11 25H2 10.0.26200.8246

Compiling OK, runnning with "cannot recycle because it is not already open" error. But it runs with continue and the "flower color play" is visible.

Hope this can help.

P.S.: Only Windows Defender like AV, with all options active, max protection.

Thanks to try it.
Hum, I dont get any message, only:

Code: Pascal  [Select][+][-]

1. An unhandled exception occurred at $00408CFE:
2. EAccessViolation: Access violation

How did you run flower.exe, via terminal or 2xclick or gdb or via Lazarus or else?

[LeP]

Open file under Lazarus IDE, it ask if it's a project, answer YES.

RUN.

[EDIT]: runs directly the exe with double click on it, it works and run right without any message.
[EDIT 1]: All settings like standard installation. FPDebugger, dwarf3 (beta)

That are excellent news.
But I do not understand why with Roland version 10.0.26200.7462 and mine 10.0.26200.8117 it crash.

I see your version is 10.0.26200.8246, so maybe there is a fix?
I will try to update my Windows version, maybe good news.

Anyway, thanks for your light.

[Fred vS]

OK. I updated my Windows 11 and now I have the same version as you 10.0.26200.8246.

But still crash at run:

Code: Pascal  [Select][+][-]

1. > ./flower.exe
2. An unhandled exception occurred at $0040910E:
3. EAccessViolation: Access violation
4.   $0040910E
5.   $0041E501
6.   $00421B0D
7.   $0041F97B
8.   $004090C5
9.   $00426C73
10.   $00402153  main,  line 139 of flower.pp

I miss something, sure, AV is also only Defender.

[LeP]

I don't think is Windows, my experience is that those issues normally were about the code, believing something that is not always true.

[Fred vS]

Could you give the command line you are using?
If you use Lazarus, menu Project/Project Options then click on Show Options.

[EDIT]: my configuration is with two video "cards": one integrated (Intel I9 14 - UHD) and an Nvidia 4070. However, using the executable alternatively or with one or the other always works.

[Fred vS]

OK, thanks.
I m busy on a Linux machine at the moment.
I will boot asap in Windows 11 and test it.
Write you later.

[Fred vS]

Sadly, using the same parameters as yours, the app still crash the same way.
I am lost.

[LeP]

Uhmm, may be is the surface used.

How do ptc work ? Do it use DDraw, OpenGl, d3d ?

If possible, try to force one tech or another.

[Fred vS]

I'm absolutely not an expert on PTC.

I think it uses DirectDraw/DirectX, but I'm not sure.

I tried to get it working as a challenge, but I failed miserably.

I stop the combat.

[LeP]

I'm sorry I can't help you further, but my knowledge on the subject is also limited.

The flower demo tests correct for 64 bit. I won't test 32 bit on Windows. All other demo's work too, as already stated.
Win11 is 25H2 26200 8246 So current release + all patches.
The suggestion that the issue is caused by win11 is bogus, at least for 64 bit.
