Hi,
I got Qt to compile by solving the following "problem" in the userland EGL /
GLESv2 code:
# Khronos
#
# Note: in Android the linker is unable or unwilling to resolve
# dynamically using already loaded symbols. The libraries here
# have quite a few circular dependencies, and so the only way
# to make it work seems to be to have everything static.
There is a circular dependency between libEGL and libGLESv2. You can fix the
Qt compile by adding the following qtbase_%.bbappend:
do_configure_prepend_rpi() {
cat > ${S}/mkspecs/oe-device-extra.pri << 'EOF'
EGLFS_DEVICE_INTEGRATION = eglfs_brcm
QMAKE_INCDIR_EGL = $$[QT_SYSROOT]${includedir}/interface/vmcs_host/linux
QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_INCDIR_EGL}
QMAKE_LIBS_EGL = -lEGL -lGLESv2
EOF
}
which just changes the order of linking to the libraries.
However, I am still not able to get the Qt eglfs programs running due to the
following problem:
* failed to add service - already in use?
which must be coming from the userland code
My problem could be caused by the fact, that changing GPU_MEM does not seem to
have any effect atm and the vc4 driver isn't loaded at startup...
Thanks for help,
David
