OpenGL ES under crouton/Ubuntu ARM Chromebook

Greetings,

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

I was able to run examples for OpenCL SDK 1.1.0 following

     Random ideas of a drinking cat: OpenCL on the Samsung Chromebook ARM, under crouton

This leads me to believe I downloaded the proper user side mali drivers.

I set BASH shell variables:

export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/home/mfilmore/Mali/lib/x11

export TOOLCHAIN_ROOT=/usr/bin/

export TARGET=arm

export DISPLAY=:0.0

I followed

  Mali_OpenGL_ES_SDK_v2.4.4/docs/html/quick_start.html

to compile samples.

Samples fail to run based on unable to initialize openGL ES:

======================

(trusty)mfilmore@localhost:~/Mali/Mali_OpenGL_ES_SDK_v2.4.4/bin_arm/opengles_20/antialias$ ./antialias

No protocol specified

Error: eglGetError(): 12289 (0x3001)

Error: Failed to initialize EGL at ../../simple_framework/src/EGLRuntime.cpp:245

======================

This leads me to believe the code is having a problem initializing the display.

Can some kind person help me out here?

Thanks much,

-Mike

  • Hi Mike,

    Chris is right that by default the CMake build system targets fbdev when cross compiling for an ARM target.  When it builds targeting the emulator, however, you can see that it builds and links against X11.  If you modify the CMake file it is possible to make it build for X11 when targeting arm too.

    Hope this helps,

    Rich
