[meta-freescale] Qt5 With Yocto Missing Libraries

[David Weston]

Hello All,

Thanks for all of your efforts - this is a great community.  I have been
reading of successes building iMX6 Qt5 systems using Yocto, but have been
unsuccessful myself.  I could use some pointers based on the details below.
Thanks in advance.

I am attempting to build an image for a imx6qsabrelite platform using Yocto
with the following features/attributes:

1.  Dora
2.  No X11/Wayland - use only eglfs
3.  Qt5 - 5.1.1
4.  OpenGL ES 2
5.  GPU Acceleration

I'm using instructions from the Wandboard guides with the modifications
listed below:

http://wiki.wandboard.org/index.php/Getting_started_with_Yocto_on_Wandboard
http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard

1.  -b dora switch is used on repo & get commands for both fsl-community-bsp
& meta-qt5 git clone
2.  MACHINE=imx6qsabrelite (also tried with MACHINE=wandboard-quad -- same
result)
3.  No patches applied

Bitbake completes successfully and produces a bootable system, however,
Qt5_CinematicExperience does not run due to missing libraries.  When the
libraries are manually installed (copied from the sysroots folder and
missing links created) to /usr/lib, the program indicates that the platform
type is not available/supported (don't remember the exact message).  The
command is : Qt5_CinematicExperience -platform eglfs .


I have some questions:
1.  Is the configuration above supported (i.e. QSabreLite/Qt5/GPU/OpenGL
ES/EGLFS)?
2.  Are any patches needed?
3.  Why aren't the libraries setup properly (i.e. missing links, missing
files)? 
4.  Is Qt5 being configured properly (i.e. libraries, platforms, etc?).
5.  What am I doing wrong/what's missing?

Additional details are listed below.

Thanks again,
David
