Could not initialize GLX

[dvosp]

I've managed to build QT 5.0.2 for an Atmel AT91SAM9G35 (ARM9) board. The CPU has a LCD controller, but no HW acceleration. The board has a running X and I've installed mesa and xcb. I can run widget apps with the xcb platform successfully, but QtQuick apps won't run, it terminates with "Could not initialize GLX" after flashing a title bar briefly on the LCD.

I have configured with:

./configure -v -opensource -confirm-license -xplatform linux-arm-gnueabi-g++ -no-accessibility
-no-cups -no-nis -no-pch -no-iconv -reduce-relocations -no-qpa-platform-guard
-no-kms -no-qml-debug -nomake qtwebkit
-system-sqlite -qt-sql-sqlite -plugin-sql-sqlite
-nomake examples -nomake qtmultimedia -nomake tests
-opengl -qt-xcb
-prefix /opt/Qt-5.0.2
-hostprefix /opt/Qt-5.0.2

Am I missing something?

I'm still not further, but I have verified that I can run the mesa demos, e.g. glxgears, although very slow.

This means opengl is working correctly, right? Does nobody have an idea why the QtQuick app won't run?
