Error: eglGetError(): 0 (0x0000)

Greetings,

I am trying to run sample code for Mali_OpenGL_ES_SDK_v2.4.4 on a SAMSUNG ARM S5P4418

I followed

http://malideveloper.arm.com/downloads/deved/tutorial/SDK/linux/2.4/quick_start.html

to compile samples.

Samples fail to run based on unable to get display. this code "display = eglGetDisplay(EGL_DEFAULT_DISPLAY);"

followed error information :

[root@S5PC4418 antialias]#./antialias

Error: eglGetError(): 0 (0x0000)

Error: No EGL Display available at /home/crl6/Mali_OpenGL_ES_SDK_v2.4.4/simple_framework/src/EGLRuntime.cpp:235

Can some kind person help me out here?

Thanks much,
