Hi,

I am trying to build a core-image-minimal image and SDK using the yocto
dizzy branch and the meta-qt5 layer.

This is for an i.mx28evk based board.

This board does not contain any hardware video acceleration, so no
OpenGL.  It uses tslib and a framebuffer.  The goal was to get a
minimal Qt5.3.2 build for this target using the meta-qt5 layer (also
on dizzy branch).

I managed to get an image to build for the target that seems to
contain the Qt bits that I need -- libraries, the tslib and linuxfb
plugins, etc.

BUT.  When it came to building an SDK, I ran into problems.

Running:

bitbake core-image-minimal -c populate_sdk

created an installable sdk, however, there was no qmake, moc, rcc, and
the other tools needed for cross compiling Qt applications.

If I instead ran:

bitbake meta-toolchain-qt5

Then the build fails while trying to build qtdeclarative:

| Project ERROR: Unknown module(s) in QT: quick-private

Googling seems to indicate this occurs because there is no OpenGL
present and qtdeclarative will not build without it.

I do not need or want declarative in the SDK - I *think* it is being included
in order to build assistant and designer, which I also do not want/need in
the SDK :)  Just the binaries required to cross compile qt
applications like qmake, moc, etc.

So - Is there a way to build a usable Qt5 SDK that includes the
required qmake, moc, rcc, etc, binaries in the configuration I am
trying to use?

I include my conf/ local.conf and bblayers.conf below.  I'd appreciate
any clues or hacks :)

LCONF_VERSION = "6"

BBPATH = "${TOPDIR}"
BSPDIR := "${@os.path.abspath(os.path.dirname(d.getVar('FILE', True)) + '/../..')}"
