Dear Thomas and Charles
In order to reproduce the issue I used the beaglebone_defconfig, changed
to linaro toolchain and activated a minimal qt5 set:
Now I have been going back in revisions and find the problem to start
exactly when switching to qt 5.0.2 (d6b2bac qt5: bump to 5.0.2). So I
have been looking through the release notes
nothing really rings a bell. But I'm not very knowledgable in the qt
So Charles, I'm interested in how you still get it working. What do you
mean with similar recipe? Do you use the qt-5.0.2 package from
buildroot? Which QT5 configs, toolchain, board?
