i use raspberry pi 4b ，after make tutorial01_first_screen and run it, get out error: `GSurface != EGL_NO_SURFACE' failed.

[cmj7010]

tutorial01_first_screen: /home/pi/OpenGL_RPI_Tutorial/openGL-RPi-tutorial/common/startScreen.cpp:107: void InitGraphics(): Assertion `GSurface != EGL_NO_SURFACE' failed.

[peepo]

search EGL_NO_SURFACE online, I found: https://pi3d.github.io/html/FAQ.html
which may be enough.

if not, one usually needs to include basic information:
the equipment you used?
had you followed all the instructions?

NB: I have not used this project for about 8 years.

good luck!
