Hey Tellie, I'm guessing that DLL is from https://download.qt.io/official_releases/qt/6.2/6.2.4/submodules/qtquicktimeline-everywhere-src-6.2.4.tar.xz ? I haven't tried to build this module...

Edit: Nope it's from QtQuick - which QtDeclarative didn't enable for some reason.

Edit2: because at the time I built QtDeclarative, I hadn't built QtShaderTools

Hey Tellie,

I set a new build of QtDeclarative going this morning and QtShaderTools was detected, so QtQuick will get built. I'll do some testing and confirm if I can reproduce your issue. It's potentially an issue with symbols not being correctly exported....

Hey all, sorry, I've had a busy week, and am heading to our holiday house this weekend.

I've been spending what little time I have updating cmake to v3.19... I got it building this morning, but its crashing whilst generating makefiles - which is less that idea.

I also discovered a problem in how cmake generates 8.3 DLL names - where it just uses the first 8 characted of the DLL name. In general this works OK.... but in cases where Qt6 wants to build Qt6Multimedia & Qt6MultimediaWidgets - then both DLL's end up being called Qt6Multi and we get into trouble.

I'll hack cmake to do something a bit more creative once I fix the crashes in 3.19...

Still working on the DLL naming issue with cmake, but I got bored and compiled focuswriter 1.8.3....
see attached screenshot...

There are definitely some issues, trying to paste from the clipboard results in a crash :) but it's encouraging.

https://smedley.id.au/tmp/cmake-3.19.8-os2-20221125.zip seems to work.... for DLL names > 8 it now uses the first 7 and last 1 characters of the DLL name; and currently isn't appending the DLL version number to the DLL name.

Hi Paul,

Thankz for the newer build :)

Most/all of the DLL names will change, so ideally, rebuild all. I'm doing a full rebuild myself to see if anything else is broken :P

Once I've done the rebuild I'll upload a new zip as an alpha so at least if anyone wants to try and port anything there is a consistent set of libs.

I also need to work out why focus writer / cmake couldn't find the qt libs, so I had to manually hack make files to get it linking ..

I tried qt-creator as that is how it is recommended to build the examples. Too much missing I think.
Code: [Select]
-- Could NOT find Qt6Qml (missing: Qt6Qml_DIR)
-- Could NOT find Qt6Core5Compat (missing: Qt6Core5Compat_DIR)
CMake Error at cmake/FindQt5.cmake:57 (find_package):
  Found package configuration file:

    h:/tmp/qt6/lib/cmake/Qt6/Qt6Config.cmake

  but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
  FOUND.  Reason given by package:

  Failed to find Qt component "Qml".

  Expected Config file at "h:/tmp/qt6/lib/cmake/Qt6Qml/Qt6QmlConfig.cmake"
  does NOT exist

  Failed to find Qt component "Core5Compat".

  Expected Config file at
  "h:/tmp/qt6/lib/cmake/Qt6Core5Compat/Qt6Core5CompatConfig.cmake" does NOT
  exist



Call Stack (most recent call first):
  CMakeLists.txt:68 (find_package)


-- Configuring incomplete, errors occurred!
See also "K:/work/qt-creator/qtcreator_build/CMakeFiles/CMakeOutput.log".
See also "K:/work/qt-creator/qtcreator_build/CMakeFiles/CMakeError.log".

I found the missing QT6Core5Compat error interesting but had other stuff to do so didn't follow up yet.

FYI - qt5compat from https://download.qt.io/official_releases/qt/6.2/6.2.4/submodules/qt5compat-everywhere-src-6.2.4.tar.xz builds out of the box... and gives me a Qt6Core5Compat_dll.a

Qt Creator 8.0.1 configure completes now...

Documenting this here whilst I think about it - I suspect the focuswriter issues with pasting are due to the hacks I made to get https://github.com/psmedley/qt6-base-os2/blob/main/src/plugins/platforms/os2/qos2clipboard.cpp building :)

Making progress with QtCreator.. some hacks required to get past build breaks...

One thing that will be needed is support in cmake for WINDOWS_EXPORT_ALL_SYMBOLS - otherwise the Proparser DLL has no exports....

OK... time for what is VERY much an ALPHA release...

Qt6 binaries/libraries - https://smedley.id.au/tmp/qt6-6.2.4-os2-20221127.zip

Focuswriter 1.8.3 for Qt6 - https://smedley.id.au/tmp/focuswriter-1.8.3-qt6-20221127.zip

I already know about a TRAP with copy/paste form Focuswriter - I've created a minimal ticket to track this at https://github.com/psmedley/qt6-base-os2/issues/1

There are BOUND to be other issues as well.

Some release notes:
1) As I stated at the start of this thread, this release would not have been possible with bww's work on Qt5 - most of the OS/2 specific changes for Qt6 were lifted straight from the Qt5 code; with build fixes coming from me.
2) There was a LOT of work to adapt cmake to a later version which was needed for Qt6; and also to adapt the Qt6 build system which completely changed.
3) QtWebEngine is NOT (yet?) included, so at this stage, there is no browser possible with Qt6. It is loosely on the agenda to try and get this building, but it's a big job.
4) Thanks to Elbert Pol and Dave Yeo, who have been testing the build system and identifying issues
5) All the code for Qt is at my github at https://github.com/psmedley
6) Currently included is:
  • qt5compat
  • qt6-base
  • qt6-declarative
  • qt6-multimedia
  • qt6-shadertools
  • qt6-svg
  • qt6-tools
  • qt6-webchannel
  • qt6-websockets

Whilst I'll continue to work on this as time permits, any sponsorship is greatly appreciated - via PayPal using the link at https://os2ports.smedley.id.au, or via the Arca Noea webstore at https://www.arcanoae.com/shop/os2-ports-paul-smedley

If nothing else - if you're interested in seeing this work continue, please comment here to let me know that I'm not wasting my time on this!

Cheers,

Paul

 Thanks Paul! Of course I'm interested in seeing this continue - unbelievable how fast you are getting results. Thanks to Dave and Tellie too for helping make it work.

Regards,

 P.S. - the link to Focuswriter gives a 404...
