Hi, I can't get B2 to start. Nothing happens at all.
B1 works ok.
I have libfftw3-double3 installed and up to date.

Linux Mint 20.2 Cinnamon 5.0.7

Just run the appimage from command line

Just paste the text printed in your terminal when you tried to execute the appimage.

Here on openSUSE I get:

Code: Select all

ed@asus:~/Programme> ./QLC+_5.0.0_beta2-x86_64.AppImage 
/usr/bin/AppImageLauncher: /lib64/libcurl.so.4: no version information available (required by /usr/bin/../lib/x86_64-linux-gnu/appimagelauncher/libappimageupdate.so)

...

followed by many more lines of debug info being printed while the program runs, until I quit and the terminal prompt reappears.

In your case it should give a hint about why it cannot be started (or crashes right away). you don't see these messages when just clicking the appimage in the file manager.

Thanks for that.

java version:

Should I install Oracle JDK? rather than openJDK.

No, Java is not your problem, or if so, a secondary one

Your system's glibc is too old, Linux Mint 20.2 comes with glibc 2.31 but the QLC+v5 AppImage requires 2.34 or later.

Posted: **Tue Jan 24, 2023 2:27 pm**

Not knowing anything about Linux Mint, it seems that it is based on Ubuntu, and you need Ubuntu 22.04+ for glibc 2.34+ (actually 22.04 contains 2.35) and thus you need Mint 21+.

Thanks. I only mentioned Java because a search on 'glib2.34 not found' gave several hits with Java. Probably Java requiring 2.34.
I'll have to update Mint if I want to try QLC 5. Not likely at this time. I'll stay with QLC4.

Might make a dent in user uptake of QLC5 if you have to update Linux Mint OS.

Thanks again for the help.

This is unexpected. I didn't think appimage would drag in such glib issues.
What I can say is if you build QLC+ 5 on your Mint distro it should work.
Otherwise I can build an appimage also on my other PC which is still on Ubuntu 20.04.

Thanks Massimo, I might get around to building it localy, but at this moment, I just don't have the time.
I really appreciate you taking time to comment.

Time constraints, family issues, and a show in February(Pantomime), don't leave a lot of time to 'play'.

Give me a few weeks, and I'll come back to it later.

I just uploaded a test version for Linux built on Ubuntu 20.04.
I tested it on Ubuntu 22.04 and it works, so luckily the ABI breakage is one direction only.
Please test it and let me know.

Works well for me

I have been silent regarding the recent massive bugsquashing and development activities, and wanted to say how much I appreciate. I am starting to test it and am seriously impressed how far it has come in the last few months.

I even have prepared a rpm package a while ago (so far only for openSUSE Tumbleweed), It seems to work just as well, but there are slight differences to the Appimage, e.g. the startup warning dialog's OK button is shifted to the right side, sticking out of the dialog, the scrollbar in simpledesk is a tad bit smaller and similar.

I try to keep it up2date, currently it's at the same state as the beta3 Massimo just created. Also I kept in the control files for other distros so that later we can work on those as well.

Yes, it starts up, and works for me. Ty.

I have a problem with a Ubuntu 22.04 installation. I normally use an old Mac to control my lights for a small venue, often for drama productions, but want to use a compact cheap 64 bit double core processor pc with a more capable usb. I had a working arrangement on my Mac and transferred everything to the Ubuntu machine generally successfully. I have an anomaly though, there are sound effects which apart from one worked, the failure was a gun shot lasting .7 sec. It only produced an instantaneous click, unless I set it to loop, where it worked fine. I have a work around, I found if I put a recording of 2 gunshots on lasting 1.4 secs it played only the second one. I have tried using mp3 and wav files. Anyone know what is causing this? To be clear the sound files play on the Mac through QLC and will play through vlc media player on the Ubuntu machine, so they seem to be fine.

Your question is completely off topic. I don't even know why you picked this thread to ask an audio-related question.
I even doubt this is a v5-related question.
Please open a new thread and don't hijack some random thread of your choice.

Because it was a long time since I started a thread, having had no issues, and despite spending 20 min or so trying to find the relevant link of details of what I was entitled to do I could not find it. In frustration I picked one which would have someone with knowledge of Ubuntu 22.04. Sorry for that, I will just have to live with my workaround and see if I find any further issues.

I'm also affected. It is not necessarily a big problem, but keep in mind that there are Debian Stable users out there. In our event technology project, all machines are running Debian stable. We'll try building from source, but if it does not make a big difference, lowering the version requirement for the AppImage build sounds like a good idea for the next release.

Thanks. The new appimage dated 0307 solved my glibc problem as well. I am on Linux Mint 19.3
