Dear All:

I have porting the minigui to imx6 linux platform, but when I run the viv opengles demo.

It prints it need the egl and X11 library !

How to make the opengles library run without X11 and egl, just run on fbdev

Thanks advance!

Please check the

ls -l /usr/lib/libEGL.so.

ls -l /usr/lib/libGAL.so.

Makesure the softlink points to

/usr/lib/libEGL-fb.so

/usr/lib/libGAL-fb.so

Prabhu, thanks for you reply.

I found the tarball /opt/freescale/pkgs/gpu-viv-bin-mx6q-12.09.01.tar.gz

but there are some prebuild library and executive bin file

when I run the viv demo, there is nothing output to the lvds screen

but I haven't got any error print on the serial terminal.

Maybe the minigui has occupy the framebuffer which is the default output of the viv demo !?

where can I get the viv demo source?

viv demo source will be available as part of GPU SDK which is scheduled to release soon. Can you please try first with the prebuilt rootfs from freescale.com.
