Lenovo T480

Describe the bug
Segmentation fault during the configure process. Unknown reason.

How to reproduce
Fresh install OS with all packages up to date and Howdy installed via official PPA. Given how new the system is I have no idea how to reproduce.

If I run configure twice in a row it will seg fault immediately. I ran mpv /dev/video0 after, mpv hangs and unable to output a video stream. I ran configure again with -m and OpenCV throws an exception. I had tried without -d but it unable to find any IR camera.

Hum, I think this is an issue related to OpenCV.

Could you past the output of ldd /usr/lib64/linux-enable-ir-emitter/libcommands.so please?

Hum, I uploaded the wrong package on the release; the v5.2.0 again instead of the v5.2.1
Please reinstall the one attached and try again.
linux-enable-ir-emitter-5.2.1.systemd.x86-64.tar.gz

[http403]

Unfortunately, the newer version doesn't solve the problem. It still seg fault when running configure and behave just like before. After the fault no other application seems able to access the device until a reboot.

However, after a reboot, -m does get pass unit 4 selector 3. It doesn't seg fault til the end but an seemingly unrelated exception from OpenCV instead.

Still, after this exception, no other application seemingly able to open the video stream again. Here an capture from Hodwy after a reboot.

I successfully setup Windows Hello on the same machine in a very dark room (it is a dual boot laptop) which I saw the IR emitters (2 total) are being triggered. This proofs the hardware isn't the problem, although I need to install a separate driver for it to work. Here's the device details. Hope this helps.

[http403]

I just realized I never use -e 2 to configure as it have two emitters. Still, specifying it doesn't change the situation.

I will try to provide you a solution today

[EmixamPP]

In pr #150 there's a bot comment that contains a link to download a tarball where I've added a --no-gui option that should solve your problem.

Please try again using the command sudo linux-enable-ir-emitter -v configure -e 2 --no-gui.

Segmentation fault

It seg fault again on unit 4 selector 3.

[EmixamPP]

I have no clue about what could be the issue, I tried using Valgrind to find a reason but there doesn't seem to be any problem on my side.

Could you try building the project yourself? All the instructions are in the readme, but if you need any help, please don't hesitate.

[http403]

I had compiled the opencv_err branch with opencv 4.5.4 accroding to the gh action, then run with -e 2 -l -1 --no-gui. I'm about 1/3 (180 86) into the configure which doesn't seg fault yet. Hopefully it split out anything other than seg fault and exceptions.

[EmixamPP]

Did you tried without -l -1? This will takes so much time and maybe you do not need the fully exhaustive search.

You could kill the process and reboot, then retry with the default parameters (just add -e 2 and also -v)

If the configuration fails, show me the output I will guide you.

[http403]

It's on 223 so not far from completing. If I quit now, its kind of wasteful.

[http403]

It is wasteful. I thought is went passed unit 4 selector 3, but it is not. It just segfault on that spot again.
