Qt6 Application Testing

[Dave Yeo]

You can also test with the window frame title with Qt5 using the DLL's at ftp://dry@ftp.os2voice.org/tmp/Qt5libs-2024-12.06.zip. Note that the window list patch that produces dots is not in these.

Thanks Paul and Rich! I went to the Netlabs website where a bunch of QT6 apps are listed, but every one I tried would lock my computer solid, even without SET QT_PM_CP-1208. I'm guessing they were compiled with an older version of QT6, from before Paul changed the DLL names. So does anyone know of working QT6 apps compiled with the most recent QT6 (besides Dooble)? I'm happy to test...

Regards,

This is rather interesting.  What programs have you got loaded ? Lock ups can also occur if all DLL's are not loaded high (marked for the kernel todo so). When testing you run other programs ?

@Martin - actually I was using QT6 apps listed here: https://trac.netlabs.org/qtapps, but thanks for the link. I'll try some of Tellie's recent ones from there.

@Dave - if I put SET QT_PM_CP=1208 in CONFIG.SYS, it will effect both QT5 and QT6 (I have both recent hotfixes)?

@Roderick - I was testing with only what runs with the WPS, no other apps. If anything, I am guilty of loading too much into high memory, although I think I have that under control now...

Hi David, yes, the Window title patch that Rich came up with for Qt6 applied cleanly to Qt5 and works here with Dooble.

When it comes to loading DLL's high there nothing to much you can load to high. However you should never mark OS2 DLL to high. Take for example PMMERGE.DLL or DOSCALL1.DLL.
Only mark data segments to load high. The key is to experiment with this to some extend. But only do this with large DLL's of QT for example.

The real weakspot of OS/2 os the lower shared kernel arena.  If it runs out of memory, well, game over.  Also loading large DLL's high will fragment the lower kernel memory area less.

 OK, went ahead and added SET QT_PM_CP=1208 to CONFIG.SYS and did some testing. Here is what I tested from the link Martin provided:

Texstudio - locks up computer, have to do a hard reset.

Tuxpaint - doesn't work - get a SIGSEGV error

LibreCAD = works, can create, save, close and open. Very Nice! Change language works too, even arabic and chinese and shows in the title bar (i think - it looks right anyway).

Chess - seems to work in a game with 2 people, but 'settings' and 'rules' don't do anything.

QTtexteditor- Russian - works, Cyrillic displays correctly in app, but title bar stays english.

Focuswriter - works: arabic got me in trouble: put the commands on the right side of the screen in opposite order, but title bar stays english.

Media Downloader - works, changing language works too. Title bar stays english.

Notepad Next - works, changing language works and shows in title bar (chinese showed squares).

QT Password generator - works, no language setting.

Tea - works, title bar is blank, don't see a way to change language.

Soduku game - works, no language setting

Zint - locks up computer, have to do a hard reset.

 Many of the above are the 'qt6210' versions if available. Only Zint with 'qt6210' did not work. FWIW, when I had a lockup, always got this POPUPLOG:

Apologies... appears I didn't do a proper git pull before the build yesterday I've deleted the 20241229.zip and now have https://smedley.id.au/tmp/qt6-6.2.10-hotfix-20241230.zip

[David McKenna]

Thanks again Paul. Don't see any obvious difference with this compared to the 1229 version...

Thanks Dave, appreciate you testing - it's also possible that I didn't screw up the 1229 version after all, but I figured it was best to be safe

I'll hopefully have some Qt 6.6 binaries for testing later today (my time). Still TBD if I can convince the webengine from Qt 6.2.6 to play nicely with Qt 6.6

[Paul Smedley]

For the brave.... and for now - no webengine included - https://smedley.id.au/tmp/qt6-6.6.3-noqtwebengine-os2-20241231-gcc14.zip

For now, installs in /qt6-6.6.x to allow it to be kept separate from a working qt 6.2.x setup.

the examples in examples\corelib\ipc\sharedmemory don't work - the code was significantly restructed and clearly I've missed something in adapting it. I suspect there may be issues in systemsemaphores as well, as that code was also restructured. Code is in https://github.com/psmedley/qt6-base-os2/tree/6.6.x/src/corelib/ipc for anyone that wants to take a look.

I'm going to experiment to see if I can graft the Qt 6.2.6 webengine onto the top of this...

[David McKenna]

Paul,

  Gave this 6.6 build a go, but I couldn't get any example to work. They all gave a POPUPLOG with this kind of error:

 Seems something is missing?

 Just for grins, I tried moving QTWebEngine stuff from 6.2 to the 6.6 directories and tried to run Dooble, but it said 'QT6Charts' was missing. That's when I noticed that some of the DLL's in the 6.6 build have different names than the equivalent ones in 6.2, so stuff will need to be re-built for this version (or DLL names kept the same).

Looks like your version of gcc1.dll isn't new enough. To be found in libgcc (most recent version: 9.2.0-5)

[David McKenna]

Hi Tom,

  I already had 9.2 installed, but you're right... I just needed the 12.2 version which was found on Hobbes. Now some of the examples work - I'll post a result of testing once I get thru all of them...

Regards,

[David McKenna]

 OK, went thru the examples. Here is a list of what does NOT work by \examples\subdirectory:

dbus - none work (no dbus running)

GUI->RHIWindow Error 'Failed to create RHI backend' then SIGABRT

Help->contextsensitivehelp: runs but doesn't work right - errors about not connecting to SQL Database

Multimedia - none work (because no backend), but in this version they actually run with an error saying no backend

Network - nothing works, but they run with various socket errors, except http which crashes.

Positioning - run but don't work

QML- all crash SIGSEGV

QMLTest - all crash SIGSEGV

Quick - most crash with SIGSEGV. A few start with 'Maximum call stack size exceeded' error but don't work.

QuickControls - some SIGSEGV, some say they can't load some component. None work.

SpatialAudio - runs but no backend.

Websockets - no crash, but nothing does anything. A couple 'Websocket not a type' errors.

Widgets -> desktop nothing works
              -> draganddrop-> deposit doesn't work
              -> touch doesn't work

 LibreCAD, Soduku, and QT password generator I mentioned  above work with version 6.6. All the others in that list either hung the machine, or gave a message saying it could not find a library (presumably because the name was changed).

[Tom]

I was referring to the rpm-package (yum update libgcc) - not the compiler itself .
