Hi,

I have problems compiling eglinfo-x11 (as well as Qt 5 from meta-qt5) with egl.

I have setup poky, meta-raspberrypi (and meta-qt5) from git and I am on branch master.

My target is to get a distribution with working (hw acceleratetd) Qt5 with QML GUI. I have already spent some days on getting qteverywheredemo running but I did not succeed yet.

As a first test I wanted to get eglinfo-x11 running but it gives the following error when compiling:

It links to libEGL and libGLESv2. nm says that this symbols should be in libGLESv2 but it just does not catch them up somehow?

My image is configured as follows:

include recipes-core/images/rpi-hwup-image.bb

GPU_MEM = "64"

LICENSE_FLAGS_WHITELIST = "commercial"

PACKAGECONFIG_append_pn-qtbase = "gles2"

SPLASH = "psplash-custopi"

ENABLE_SPI_BUS = "1"

IMAGE_FEATURES += "ssh-server-openssh splash x11-sato"

IMAGE_LINGUAS ?= "de-de es-es fr-fr en-gb"

Thanks for help!
