I am developing a Qt gui application to run on my RPi2 board. I followed the instructions at RaspberryPI BeginnersGuide to crosscompile Qt. The requirement is to run the application on a mini (2.8" preferably) display. I tried to run my app on the Adafruit PiTFT - 2.8" Touchscreen Display. But it fails with the following error:
./myApp: error while loading shared libraries: libGLESv2.so: cannot open shared object file: No such file or directory
From this link, I found out that pitft does not support openGL. Since Qt5 on RPi uses OpenGL for rendering, does it mean that I cannot run any of the Qt GUI applications on this display? If so, is this case true for any display with an interface other than hdmi/composite? or is my understanding wrong?
Can somebody please suggest me a mini display on which I can run my Qt gui apps?
