lib egl2 fail to authenticate on RaspberryPI4 (and presence of /opt/vc folder seems to be issue) #374

Open monkstone opened 2 years ago

I'm not sure whether vc library is required for the built in Camera interface but it just isn't needed for RaspberryPI4 graphics to function well. I use ManjaroArm (64 bit) on RaspberryPi4. With standard video setup in /boot/config.txt.

# See /boot/overlays/README for all available options

gpu_mem=64
initramfs initramfs-linux.img followkernel
kernel=kernel8.img
arm_64bit=1
disable_overscan=1

#enable sound
dtparam=audio=on
#hdmi_drive=2

#enable vc4
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
disable_splash=1

Otherwise congratulation on processing-4.0b4 release. To be clear fix was to remove the /opt/vc folder (it's presence also interfered with PiCrate).

What was the context in which you ran into this error? Just when starting the software? Trying to do something that used OpenGL?

I'm now unsure how vc got installed (it might be legacy), but problem was when running OpenGL sketches from processing ide or PiCrate directly. Error suggests a permission thing, my user is member of video group. Unless you get further complaints I wouldn't worry about it.
