Hello everyone

I'm new to using QLC+ on the Raspberry.
I have done the manual installation, described in chapter 10. The first problem is, that libinput5 can not be found. The next problem is, after successful installation and execution of "qlcplus -platform xcb" I get the following message

Code: Select all

pi@qlcplus:~ $ qlcplus -platform xcb
qlsplus: error while loading shared libraries: libGLESv2.so: can not open shared object file: No such file or directory
I hope someone can help me.

greeting
Damian

Which Raspbian version are you using ?
I haven't checked Stretch yet (released officially a week ago?) and I'm pretty sure there will be issues there.
You might have more luck with Jessie.

I've tried it with Raspbian strech. I have Jessie installed and qlc + starts :-)

But I now have the problem that my touchscreen does not go as long as qlc + runs. In the XDesktop of Jessie the touch function works perfectly.
Any idea why it does not go in QLC + so I need an external mouse?

This worked for me

Look at MineCraft and then copy symlink to /opt/vc/lib

Code: Select all

root@raspberrypi:/opt/minecraft-pi/lib/mesa# ls -ltr
total 12
lrwxrwxrwx 1 root root   43 Jul  5  2017 libGLESv2.so -> /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2
lrwxrwxrwx 1 root root   40 Jul  5  2017 libEGL.so -> /usr/lib/arm-linux-gnueabihf/libEGL.so.1

Code: Select all

root@raspberrypi:/opt/vc/lib# ls -ltr
lrwxrwxrwx 1 root root     36 Feb 27 09:51 libEGL.so -> /opt/minecraft-pi/lib/mesa/libEGL.so
lrwxrwxrwx 1 root root     39 Feb 27 09:52 libGLESv2.so -> /opt/minecraft-pi/lib/mesa/libGLESv2.so

Any update on new build for strech? It seem to have qt5 and it sort of works, but I have no icons.

thanks

Unfortunately no good news.
I spent a whole day on Stretch but I am not able to cross-compile Qt the way I want (using proprietary driver on EGLFS without X11, and using VC4 Mesa driver on X11)

I copy the MESA driver from Minecraft and it worked, any idea why I have no icons? Do I need to set some theme? Everything seem to work nicely..

Thanks for the good work !
