I've been able to narrow my problem futher down:
the meta-raspberrypi layer contains a bb called "userland_git.bb"
(meta-raspberrypi/recipes-graphics/userland/userland_git.bb).
the source for this layer is github.com/raspberrypi/userland.git. I cloned
this repository and searched for the undefined references.
This repository contains the source code for the ARM side libraries used
on Raspberry Pi. These typically are installed in /opt/vc/lib and includes
source for the ARM side code to interface to: EGL, mmal, GLESv2, vcos,
openmaxil, vchiq_arm, bcm_host, WFC, OpenVG.
I had success! All my undefined references are defined in
userland/interface/khronos/glxx/glxx_client.(h|c).
But still I haven't figured out how to get this build correctly so qtbase
can find and use it.
Any suggestions?
