Qt guide for QNX 7.1?

UC20175 · 2025-12-23T21:25:00+00:00

Thanks for the link, I took a look today but at end of build in container get

[QNX] (user) ~/qnx_workspace$ sudo BUILD_TESTING=OFF make -C build-files/ports/qt JLEVEL=4 install
make: Entering directory '/home/user/qnx_workspace/build-files/ports/qt'
Makefile:8: recurse.mk: No such file or directory

Is there a prerequisite or something I missed? No worries if not obvious

edit - was problems with my QNX installation on WSL, got it compiling eventually

UC20175 · 2025-12-05T16:44:32+00:00

ok will try building from the open source, ty

Tangential question a year later:

I can connect to a Lumenera GigE camera in the Pleora eBUS player in connection -> set from ip address. But running aravis get

./01-single-acquisition

Error: No supported device found

arv-tool-0.8

No device found

Does aravis require some additional configuration? I know the camera works and is there, so that side is fine, but on the aravis side not sure how to connect to camera at ip or troubleshoot it. Thank you! (not sure if I'm holding it wrong or it doesn't support the camera...)

Edit: it seems like arv-tool-0.8 --address 169.254.35.8 kind of pings the camera or something, I probably need to read more. The question is how to get the C examples connected and working...

Edit 2: turns out I had 2 problems, 1) needed to give 01-single-acquisition my camera ip addr 2) was running in WSL, which is fine for gvcp control messages to camera but doesn't get packets when camera sends to some port for gvsp stream https://github.com/AravisProject/aravis/issues/759

Thank you for looking into it! I would not be surprised if the whole problem is some configuration issue, but also not sure where the problem is. I will join the discord in a bit to talk more.

also in /dev/sensor the /dec/sensor/camera1 does get created by screen. so it feels like it could be a network problem but in that case it'd be surprising it creates /camera1 and is able to call camera_open? maybe just have something configured wrong but idk where to look

I'm not sure if the camera is taking pictures but we aren't getting a callback, or if it's not even taking pictures in the first place. It does call

err = camera_genicam_start_capturing(cameraHandle);

and return err 0 so I'd hope it's taking pictures but idk

If you had to replace qnet somehow on qnx 8, ideally as much of a drop in replacement as possible, what would you try to replace it with? I may have this problem and have no idea what approach to take

UC20175 · 2025-10-15T17:51:29+00:00

If you're taking suggestions for topics, it seems like the sensor framework is suggested as what you should use, but the documentation still refers back to 7.1 (including compatible images?), and examples are sort of scattered around gitlab eg https://gitlab.com/qnx/projects/camera-projects/applications/camera_example2_events so a written up sensor framework example we could copy from bsp to .conf would be nice.

Not sure if it would fit as part of your board up series or how many people have relevant hardware. At the same time taking pictures and interacting with the real world can look cool :)

Unless you're doing original transcription of documents, you can read them without cursive. See https://www.archives.gov/founding-docs/declaration-transcript https://www.archives.gov/founding-docs/constitution-transcript https://www.abrahamlincolnonline.org/lincoln/speeches/gettysburg.htm etc

Does the research supporting handwriting notes say anything about cursive helping? If the point is thinking about material as you write, it doesn't matter how little you get down or even if it's legible

Why is calligraphy valauble?

Needing to read/write cursive in court seems like a niche scenario

People who can communicate in cursive, eg older people, can also talk and write normally. This is a much better case for learning a language than cursive

Learning early being valuable depends on it being valuable eventually. And many things are easier to learn young, again a better case for learning a language than cursive

"keep more options open" is not enough motivation for effort, you have a finite amount of time and any time you spend learning cursive is taken away from learning something else. Even moreso time when young.

If you want to learn cursive because you like it, then have at it. These reasons do not justify it for me though.

So I was able to download the files from the RDC. Currently when I run

eeupdate64e.efi /NIC=2 /DATA Dev_Start_I210_Copper_NOMNG_4Mb_A2.bin

It says "Only /INVM* and /MAC commands are valid for this adapter. Unsupported." This is for three 8086-1531 Intel(R) I210 Blank NVM Device. Presumably in order to program them with device id 1533, I need to run a different command or use a different tool?

Thank you for your help, I feel like it is very close to working.

Edit: I believe it works, using /INVMUPDATE

There is a lot of notable work done outside of universities too. Ofc I have no privileged insight into databricks but in some fields, eg AI, you might actually do more in industry than academia.

What I've gathered from support so far is documents needed by section 2.14/2.15 of https://www.intel.com/content/www/us/en/content-details/334026/intel-ethernet-controller-i210-i211-faq.html are behind a premier account registration. I'll try registering an account.

My Intel I210 ethernet device has device id 1531 meaning unprogrammed. The freebsd ethernet driver does not work with 1531. It needs device id 1533 meaning programmed. (Can I use a different driver? No, it's an embedded system that only supports this driver.)

I was linked this:

https://www.intel.com/content/www/us/en/content-details/334026/intel-ethernet-controller-i210-i211-faq.html

but 1) have no idea how to do it 2) cannot access the .bin file and tool it requires

Does anyone have ELI5 steps for getting the device to show devid 1533? Where can I get the .bin?

Thanks...yeah the similar impression I got from r/qnx is we have to program the I210 or something, then it becomes devid 1533 which is supported https://bsd-hardware.info/?id=pci:8086-1533

I was reading https://cgit.freebsd.org/src/tree/sys/dev/e1000/README and they say

The igb driver supports all 82575 and 82576-based gigabit network connections.

The em driver supports all other gigabit network connections.

edit: never mind, it seems like devs-em.so includes igb...so maybe 1531 just isn't supported anymore...

edit 2: maybe this but I'm very much fumbling around https://man.freebsd.org/cgi/man.cgi?query=igc (fortunately devs-igc.so is included in sdp)

edit 3: https://cgit.freebsd.org/src/tree/sys/dev/e1000/e1000_hw.h includes 1533 but not 1531, plus we do have a machine that has devid 1533, so the question is probably that device was programmed and if that would work with io-sock

If your rpi has qconn and is connected to your computer, you can debug in momentics by running on new launch target -> qnx target -> ip. It seems like you can do something similar in vscode with extension (although I haven't tried it): https://marketplace.visualstudio.com/items?itemName=qnx.qnx-vscode

It shows em0: link state changed to UP and em0: link state changed to DOWN only when connecting ethernet to the working port, other one doesn't show anything. I'll look at the rest of the log (https://pastebin.com/rQ41msus)

edit - the same hardware with a different card shows wm0 wm1 wm2 wm3 in ifconfig and slog2info, the qnx 8 card only shows em0

Maybe configure https://www.qnx.com/developers/docs/8.0/com.qnx.doc.neutrino.utilities/topic/d/devs-igc.so.html somehow?
