Xlib: extension "XFree86-DRI" missing on display ":0" When I execute the gpu example

[deanji]

Hi All：

When I execute the gpu example(gpu_sdk_v1.00\Samples ,compiled success) ，Encountered an error：Xlib: extension "XFree86-DRI" missing on display ":0"

i has did some changes as the following:

> sudo ln -s libGAL-x11.so libGAL.so
> sudo ln -s libEGL-x11.so libEGL.so
> sudo ln -s libEGL-x11.so libEGL.so.1
> sudo ln -s libVIVANTE-x11.so libVIVANTE.so

libs of above was compiled use ltib

my board info: imx6q，bsp version is 3.0.35

what do i need to do next for the problem? 

thanks!

as I known, ltib don't have x11 currently, you can move to yocto which has x11.

for how to download the yocto bsp, pls find it from official link.

<Embedded Linux for i.MX Applications Processors|NXP >.

focus on the "Board Support Packages" to download the bsp you need.

My view is that ltib can compile the X11 library, which means that ltib supports X11!

[joanxie]

did you use x11 successfully? as I known, current bsp coudln't suppor it, if you need to use , you can refer to the yocto then change.

Thank you for your reply!  My ultimate goal is using the opengl in my qt program ! You mean i can not use opengl in 3.0.35 (complied from ltib)??
