Hello.

Tellie just ported "uchmviewer", an epub book viewer, using Qt6.
It also requires the Qt6 ffmpeg DLLs.

- http://rpm.netlabs.org/test/QT6/uchmviewer-test.7z

Please test it out too.

Regards

[Paul Smedley]

Tellie asked me on IRC about a build of Qt 6.5.3 - so here it is - https://smedley.id.au/tmp/qt6-6.5.3-os2-20230930.zip

No OS/2 specific fixes over the previous builds  - and no webengine due to the issues with building the v8/javascript engine (see https://github.com/bitwiseworks/node-os2/issues/1)

Thanks Paul,

  I gave it a try using the examples provided and notice right away that I get a lot of 'module 'workerscript' not found' messages with qml examples. That was a problem with earlier versions that you fixed at one point...

Regards,

[Paul Smedley]

Yep, seems I forgot to configure qtdeclarative with '-no-feature-qml-worker-script' - rebuilding it now

https://smedley.id.au/tmp/qt6-6.5.3-os2-20231015.zip might fix the workerscript errors.

[Paul Smedley]

https://smedley.id.au/tmp/qt6-6.5.3-os2-20231017.zip  is rebuild using latest bww cmake. DLL names have changed so this will break compatability with any apps built against previous 6.5.x drops,  however it should make future maintenance easier (for me).

[David McKenna]

Thanks Paul,

  Did a quick check of some examples with this one and I don't see the 'workerscript' error anymore, but now see things like:

'module "QtCharts" plugin "qtchartsqml2" not found', or 'module "QtQuick.particles" plugin "particles" not found' (many others too) with qml stuff. Don't remember if this happened before. Maybe more DLL name length adjustments needed?

 Also I commonly see: 'RangeError: Maximum call stack size exceeded' in failed tests.

 I'll do some more checking after work....

Yep - I think this is the 'qmldir' issue - I need to work out how to write the 8.3 filename into qmldir...

[Paul Smedley]

Some of the qml issues are almost certainly due to https://github.com/psmedley/qt6-declarative-os2/issues/2#issuecomment-1784224726

I've worked around these now and am rebuilding....

[Paul Smedley]

Hey all, as I alluded to in the Development thread, I'd spent the last few days updating the Qt 6.2.x branch to the latest opensource release (6.2.6). The first public builds of this are available from https://smedley.id.au/tmp/qt6-6.2.6-os2-20231108.zip

The intent behind focussing on the 6.2.x is to try and get a stable(ish) build of the browser. Dave Mckenna and Tellie have done some limited testing of the non webengine components, but the webengine has been tested only as far as to see that a page loads (it did!).

No attempts (yet) to try youtube or to use the separate vpx and av1 dll's that helped with youtube previously.

The chromium version in this build is the same what was included in Qt 6.3.2.

Dooble build to match this will follow - hopefully today.

Cheers,

Paul.

Have you checked out https://github.com/komh/dav1d-os2, there's also https://github.com/komh/libvpx-os2 at 1.8.

Dooble build at https://smedley.id.au/tmp/dooble-20230830-os2-qt62-20231108.zip

Not yet.... I'd kinda like to understand why compiling the ASM as part of qtwebengine doesnt work - I did notice that nasm reports a warning whilst compiling the ASM - see https://github.com/psmedley/qt6-webengine-os2/issues/16 - which may be part of the issue...

Cheers,

Paul

I see your zip files are still somewhat broken, File Commander won't unzip them and manually, lots of warnings about absolute path spec,

Code: [Select]

warning:  stripped absolute path spec from /dooble/README.md
  inflating: dooble/README.md         (160 bytes EAs)

YouTube is sure CPU intensive here, takes minutes before I can open a video and the homepage is only displaying the first few videos, rest are grey rounded rectangles.
Switched to single process mode, seems even slower and see this warning,

Code: [Select]

[153:1:1107/194354.214000:ERROR:system_network_context_manager.cpp(299)] Cannot
use V8 Proxy resolver in single process mode.

Hopefully not important. I'll add to this post whenever Dooble allows me to open a video.

[Dave Yeo]

Eventually it locked up the system, twice. Starting with a new profile, Dooble would vanish when it started rendering YouTube.
For regular browsing it seems fine.
