I have tried compiling QLC + 5 and when I run appimage I receive these errors and a blank white window.
OS: Ubuntu 18.04
QT: 5.14.2

I haven't created an appimage in a while.
I probably need to review the Qt libraries that get included.
One thing I know for sure: don't use Qt > 5.13.0

Hi Massimo,
How can I test the latest changes in QLC+ 5 without interfere with the normal QLC+ 4 installation?.

In Linux the only way is via AppImage.
QLC+ 4 and QLC+ 5 share the same engine, but with a few build differences, so they're not binary compatible.

In the meantime I fixed the 2 major issues QLC+ 5 had on Qt. Now I can fix the appimage creation too. I think I will bundle Qt 5.14.2.

[EDIT] pushed. Please check if it is OK now with Qt 5.14.2

I will try it later and inform you of the results.
I tried yesterday adding libQt5QmlModels.so.5 to linux.pro and it did not work. Now I see that you removed some references to libQt5MultimediaQuick versions too.

Regards

Santi

I tried yesterday adding libQt5QmlModels.so.5 to linux.pro and it did not work. Now I see that you removed some references to libQt5MultimediaQuick versions too.
libQt5MultimediaQuick was a duplicate. See a few lines above in the .pro file.

The output of ldd you're showing is not the one expected. It should show paths inside the appimage folder. Are you sure you have chrpath installed? It is required by the appimage creation script (it's written at the beginning of the script...)

In any case it might be necessary to add libQt5QmlWorkerScript too

First the good news, it's working now. I installed chrpath and added libQt5QmlWorkerScript.so.5 to linux.pro.
Bad news, video don't work. The video properties don't show duration, resolution and video and audio codec. The audio files are working well.

hi,
I would like to try it because I'm starting some theatre rehearsals and it's a good occasion for mistakes :)
someone would be so gentle to share the appimage?
I've tried to build it this morning but when I lunch it it says no qmlui found and I'm not so tech to investigate it.

I managed to built it on a desktop with qt 5.15.0.
Sure that it's too technical for me, my build is too buggy and I didn't dare to try it for real in this state, even just for rehearsals.
Hopefully your experience will be better.
