Q Light Controller+

Posted: **Fri Mar 17, 2023 11:46 am**

Hi,

I'm having trouble building the software from source, so I just grabbed https://www.qlcplus.org/downloads/test/ ... 4.AppImage which seemed somewhat recent. The commit log since that date don't seem to mention related issues.

What I do:

- create two dimmers (can be generic dimmers or spotlights)
- switch to simple desk
- raise fader one
- raise fader two
- observe crash

It is reproducible for me with the attached showfile;:
- go to simple desk
- raise fader 1
- raise fader 2

Result:

I didn't find recent bug reports of a similar issue, but I understand that I might have missed them. Thank you for working on this project.

I tested on Ubuntu 22.04 with same test version, no crash here.

Posted: **Sat Mar 18, 2023 7:13 pm**

Tested on Windows 10 x64, 5 beta 2, no crash.

Posted: **Mon Mar 27, 2023 7:13 am**

Same crash on windows 11

Posted: **Mon Mar 27, 2023 10:47 am**

Same issue here, debian 12 with the last appimage 20230307.
I had this issue last Saturday, systematically, my file was 5 months old so I thought that maybe it was a version problem.
Tested again now with the new file uploaded and I confirm the crash.

Windows here - latest GIT - NO crash

I confirm this is still present. I can add that this problem is only for different fixtures. If you add fixtures with multiple channels, it does work until you fade a second fixture.

I tried QLC5 (beta3-test as I am on Debian linux and beta2 directly crashed with the `GLIBC_2.34' not found.

But I'd like to highlight, that I face the same trouble as described here:
as soon as I try to raise a fader for the second fixture in the simple desk I get a seg fault as it tries to access an unexisting fixture on a weird universe:

Code: Select all

[Simple Desk] get fader for universe 8388607 fixture 4294967295 channel 4294967291

Currently I am not in the mood to compile and debug it myself, but if I can help something with testing I'd like to help!

(If you prefer this as an issue on github, let me know)

Thanks for the great work!

Which beta3-test exactly?

I have here QLC+_5.0.0_beta3-TEST-20230307-x86_64.AppImage from where I don't remember, but beta2 (QLC+_5.0.0_beta2-x86_64.AppImage) fails with:

Code: Select all

qlcplus-qml: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by qlcplus-qml)

and I remember that I searched for the issue and found a link in some (forum?) post to this beta3. If I can try something else, let me know.
