Qt6 Application Testing

Interesting, wonder what it is in my environment causing this? It is consistent here.

Reinstalling seems to have fixed things

hi all

please try the latest Nomacs...

Hi Elbert,
I have tried your nomacs port, but it won't start:

{0}[e:\programs\nomacs\bin] nomacs
SYS0002: The system cannot find the file specified. "RAW23"

If I try:

{2}[e:\programs\nomacs\bin] chkdll32 nomacs.exe
Loading DLL 'libcn0' --> E:\USR\LIB\LIBCN0.DLL.
Loading DLL 'libcx0' --> E:\USR\LIB\LIBCX0.DLL.
Loading DLL 'Qt6Core' --> E:\OPT\QT6\LIB\QT6CORE.DLL.
Loading DLL 'gcc1' --> E:\USR\LIB\GCC1.DLL.
Loading DLL 'Qt6Widge' --> E:\OPT\QT6\LIB\QT6WIDGE.DLL.
Loading DLL 'Qt6Gui' --> E:\OPT\QT6\LIB\QT6GUI.DLL.
Loading DLL 'nomacsC3' --> NOT loaded!
Unable to load DLL 'nomacsC3'.  DosLoadModule returned: 2
OS/2 reports 'RAW23' contributed to the failure.

I get the following error. I have set beginlibpath=E:\Programs\Nomacs\lib;E:\opt\qt6\lib.

best regards

Hello

Please let me know what do you think. I will like to have the Qt6 libraries on RPM/YUM (On Netlabs if possible). Even if the webengine is not finished yet, I think that the other Qt6 ported apps are good for use.

Maybe Qt 6.8.1 can be available at the RPM/YUM so we can start mainstreaming the Qt6 apps that get ported.

Comments?

Regards

[Jochen Schäfer]

And, please don't forget to package translations.

Hello

According to other thread it seems a bad idea to try to go "mainstream" (put it on the RPM) with Qt 6.8.1 at the moment.
Maybe we should start with 6.2.6 and wait if there are some progress with versions 6.7 or 6.8.

Qt also has LTS (Long-Term Support releases) versions, It seems that Qt 6.5.x(LTS) is the one will hold to 2026-03-30, then it cames Qt 6.8.x to 2029.

Hi !

I just found something and don't know if this could be helpfull.

I used latest Dooble QT6 with latest QT6.2.x build
As often, the system get frozen (unresponsive) and had to power off/on to recover

Once again, the system got frozen but before power off/on, I tried to unplug/plugin my usb dongle used for the mouse and keyboard
and Oh !  it allowed me to use the keyboard and mouse for several seconds and frozen again and doding the same action allow me to have the hand on the system again....

What I could see:
- processor have a lot of high CPU spikes in continous (making it go into frozen state in loop interrupted by the usb mouse dongle which provides enough time to issue some commands)
- Trying to use the stop or reboot option from the xcenter will put it into a final frozen state.

During a between time of frozen state, I saw under theseus that dooble is always loaded into memory.
I could take a copy of theseus dooble process while having got mouse/keyboard back for a few seconds.

[Remy]

Again, system frozen state.

Could get out doing: unplug/plugin USB wireless dongle then kill Dooble (do not exit but kill)

I've got a second time a frozen state and before killing it, I could take several theseus outputs I put into a zip file.
May it be helpfull to find the problem ?

A process dump might be useful...

Ok,
