Could not find the Qt platform plugin "eglfs" in ""

What I meant is to take a look at the tests that have been run during the Qt configure step to see why they failed.

@JKSH I looked at the link you mentioned and tried to implement it. But in step 13
echo /usr/local/qt5pi/lib | sudo tee /etc/ld.so.conf.d/qt5pi.conf, I don't have a file namedqt5pi.conforqt5opi.conf. Could I be unable to reach the point I want because of this?By the way, I'm already doing the process in steps 14 during the installation.
I'm trying to find where I went wrong. I think it will take a very long time. :/

Take a step back: Don't worry about Qt first; make sure the EGL libraries are working on your device.

libbrcmEGL.so(orlibEGL.so) andlibbrcmGLESv2.soin /opt/vc/lib. Are the libraries there there? Do the triangle examples work on your device? -

@JKSH @SGaist Hello again, I'm back with another thought.
As in Raspberry Pi,
/opt/vc/libdirectory does not occur between Orange Pi directories. I created this directory manually in Orange Pi. I am also copying the files in the directory from the/opt/vc/libfolder within the Raspberry Pi ecosystem to a Flash Drive.cp -rL /opt/vc/lib /media/pi/SANDISKThen I insert this memory into Orange Pi and copy it to the
/opt/vc/libdirectory I created in the Orange Pi ecosystem.cp -r /media/pi/SANDISK /opt/vcBut between two different directories, different views emerge as I added in the photo below. The
libGLESv1_CM.sofile I show with the red frame looks different between directories.
Could my process be incorrect? How accurate is it to copy like this? This is where my error most likely stems from.

I suggest you seek help at a Raspberry Pi forum first. Make sure that you can run the examples at https://github.com/matusnovak/rpi-opengl-without-x first.
After that, you can try building Qt and the EGLFS plugin again.
Good luck.
