libEGL warning: DRI2: failed to authenticate

[Lily]

After I type br -gui -algorithm "Show(false)" -enroll 0.webcam

It showed 

libEGL warning: DRI2: failed to authenticate

Set algorithm to Show(false)

Enrolling 0.webcam

HIGHGUI ERROR: V4L/V4L2: VIDIOC_S_CROP

00.00%  ELAPSED=00:00:07  REMAINING=596:31:23  COUNT=41

Can anyone tell me how to solve the libEGL warning: DRI2: failed to authenticate problem ?

I got this problem to go away by doing this:

$ sudo ln -fs /opt/vc/lib/libEGL.so /usr/lib/arm-linux-gnueabihf/libEGL.so
$ sudo ln -fs /opt/vc/lib/libEGL.so /usr/lib/arm-linux-gnueabihf/libEGL.so.1
$ sudo ln -fs /opt/vc/lib/libGLESv2.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so
$ sudo ln -fs /opt/vc/lib/libGLESv2.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2

What OS are you using? My Webcam will not enroll. I am using Raspian.
