[Buildroot] the problem with Xorg, QT5 and imx vivant dirver

[Zhaozhou Meng]

Hello,

I'am new to buildroot and I'am working on the buildroot 2016.05 for a
project based on the board nitrogen6x, freescale imx6q.
I want to build the QT5 using eglfs, egl and opengl and the Xorg using the
imx vivant driver.
So I choosed :
X11 as freescale imx-gpu-viv output option ,
xf86-video-imx-viv as X11R7 driver,
QT5 Desktop Opengl as opengl support
and others necessary packages, like gstreamer 1.0 but I didn't choose the
opengl in gst1-plugins-bad.

During the building, I have always the errors with qwidget.so like
[sub-src-mak-first] error 2.

Is there any conflict between the xorg and the QT5 or it is the other
problem ?

Another question is that when I choosed the xf86-video-imx-viv as X11R7
driver, the mesa3D is choosed, it means the imx vivant driver depends on
mesa3D ?

Thanks all of you.

The output of building like this:
