Programming / Re: Building Qt5
« on: November 23, 2022, 08:03:49 am »
Dave, if I understand it correct, the problem is our gcc. So it would be necessary to fix gcc not Qt. What you propose is a work around for a bug in our gcc which only exposes on OS/4 kernel. Correct?

Good sum up Sigurd. Only -

UEFI BIOS needs GPT HDD Layout (only Exception: The UEFI BIOS uses the CSM Mode if present!)
is wrong I think. I'm not really sure but I think UEFI can work with MBR disks without problems. Only Windoze does not support UEFI without booting from a GPT disk. But....

After seeing the presentation (parts of it) I'm confused too. One thing to remember is UEFI is different thing than GPT. Moreover Secure Boot seems to be another separate thing. Although these three things may come at once with a new Windoze notebook these are separated things.

To my understanding it is developed by (or to be more precise organized by, or developed under control of) ArcaNoae. As usual with a lot of parts in ArcaOS there are some ArcaNoae people involved but also some other developers/testers/translators/volunteers....

Both, UEFI and GPT, needs changes in different places of the OS. So different people work on different tasks. But as far as I can see (mind I don't speak for ArcaNoae) they are all organized by ArcaNoae. Some of them may be paid or not.

Applications / ssh - sshd
« on: October 30, 2022, 06:58:59 pm »
I want to set up a ssh server on my system. I've not much experience with SSH until now. I installed the openssh packages (yum install openssh-servers ..) but can't start the daemon.

I tried all combinations with or without path like p:\usr\sbin\sshd.exe or P:/usr/sbin/sshd.exe ... but I get always -
Code: [Select]
sshd re-exec requires execution with an absolute path

Anyone running successfully an ssh server on OS/2?

I was curious as to what you think may need to be accomplished to access audio through HDMI - I know Arca Noae has a version of SNAP that needs updating on the bucket list and of course Panorama - do you think either of these drivers could be updated to interleave audio support through HDMI,
I don't know how the Linux guys do it but given the system design thinking about the basics. The system design is as following
- audio card/chip is digitally connected via PCI(e) to the CPU and the output analog audio goes straight to the attached connectors (yes there's also a digital stream to S/PDIF but that's a completely different thing than digital PCI(e)
- video card/chip is connected via PCI(e) to the CPU and the outputs of these chips go straight to there associated connectors

Video chip is controlled by the video driver, audio chip by the audio driver (which have to work together with the multimedia subsystem). Now you ask for a cooperative video driver and a cooperative audio driver. Audio drivers should send audio data to the video chip at the same the the video driver operates it. Both data streams have to be synchronized and proper mixed together in the video chip (to be more precise feed into the video output DVI/HDMI LVDS driver which today most probably is integrated into the video chip).

I'm mostly a hardware designer and system designer but did professional software development too. I'm not the Linux expert and not the in dept expert of PC hardware I was years ago. But to me this all looks way to complex for us (OS/2 developers) to spent a lot of thinking about. I know some things about our video drivers and think David has a lot of more important things to do than thinking about the quirks of mixing some audio stream into some video chip. I'm pretty sure there is NIL BIOS support for that so I see no chance to make such thing happen with Panorama. In theory with SNAP and a special video chip driver there would be more options. But if you think about the huge problems to improve only small pieces in SNAP, it's pretty clear that even if someone could reanimate SNAP there would be tons of other more important problems to solve before.

Btw. personally I circumvent these crappy consumer interface HDMI as much as I can. I participated the invention of this interface during my active career in consumer electronics. I know the reason why it was made and for which use cases it is good for. And so for the few times I use my PC for audio reproduction I prefer my AV-Receiver connected via S/PDIF with the attached big speakers over any monitor built in lowest end speaker. So take my thoughts above as strongly biased ;-)

Display Port is similar to HDMI and only needs a passive connector to convert.
You mixed up DVI with DP (Display Port). DP is quite different compared to DVI and HDMI. HDMI uses the same electrical signals as DVI has used before. So a simple passive converter can be used to interchange them. For video signals that is. DVI does not support audio officially.

For DP to HDMI the the graphic chip/motherboard has to detect a external adapter and switch different (HDMI) output signals to the DP connector. Not all motherboard can do this. Don't count on this special function. It's not mandatory.

It does raise the question of how resolutions are changed in UEFI mode. Does it depend on the hardware or does the mini driver take care of it?
I don't understand your question here. But beside UEFI or not, the list of possible resolutions does depend on 'current' (at boot time) hardware and BIOS and BIOS settings. F.i. on a desktop system the list of resolutions is different (and has to be different) based on the external monitor you connect AND based on the interface on which you connect it. Afterwards (after booting) it usually depends on the OS to react on changes (undocking, connect external monitor, ...) 

I think for us it does not change very much. On modern systems you have to read out the information from the (UEFI-)BIOS and act on what it offers. There seems to be no standard way anymore to deal with such things. Even worse when the system runs we should detect new monitor on other interface at least and at least activate this interface too with the same resolutions as before if possible. The traditional way, activate all interfaces and send out same signal to all, does not work since a while. F.i. HDMI is not capable to transport the same resolutions than DP.

Maybe things would improve if we would have enough interested and talented developers and if we had open source Panorama and if we had open source ACPI. Could be that some people would try to improve there own system in some aspects (resolution, power saving, ...) and other people would benefit. But too much 'if' and speculating here.

Setup & Installation / Re: MARKEXE vs EXECMODE - differences?
« on: October 16, 2022, 09:59:55 am »
I can't go above VIRTUALADDRESSLIMIT=2816 with this system. Otherwise AOO can't open some dlls anymore. But it also depends on other settings.

I've solid hangs a while after I start Thunderbird (beside SM) with my different calendars located at different sites. On my older system I had solid hangs often when playing videos. No clue if audio or video related.

I've numerous PL2303 adapters which do not send/receive extra characters. Neither with the old PL2303 driver from hobbes nor with the latest usbcom from ArcaNoae.

Open Watcom Debugger supports dwarf,
Yes. But most probably not the current version of dwarf I fear.

Beside that if you've ever used a more modern debuger (idebug, ICAT, every other debugger out in the world from this century!) you'd never want to switch back to the ancient user interface experience of wdebug.

I load it and then un-load it when my script has completed running.
I'm not a REXX expert in any way. And what I've to say probably will have anything to do with your problem. But, once I read you should never unload a rexx dll. AFAIR this is because there might be other rexx scripts running which still needs the dll loaded. Maybe my memory is wrong on this, but....

Both VAC and C Set/2 can be installed by unpacking ...
I think the problems start with VAC4.0 and it's help system which needs a server and a lot of settings in config.sys. Think the included 3.65 version needs the 'new' help system too.

There was an excellent presentation about JFS at one of the Warpstock Europe events. I think it was this - http://wse2009.warpevents.eu/uploads/tx_wseevents/APP02-JFS-Cache.pdf
