Hi I need qt-gstreamer in my Qt5 app (because I am having problems with the camera element).
I found a yocto recipe from Andrey Telepin and tried to modify it for Qt5. It looks like this: ----------------------------------------------------------------------- LICENSE = "GPLv2" LIC_FILES_CHKSUM = "file://COPYING;md5=2d5025d4aa3495befef8f17206a5b0a1" SECTION = "multimedia" PR = "r0" SRC_URI = "http://gstreamer.freedesktop.org/src/qt-gstreamer/qt-gstreamer-0.10.3.tar.gz" SRC_URI[md5sum] = "a5f73dfa50270a23a0b07af32304e162" SRC_URI[sha256sum] = "bfc4406bde003d9e2e9b7fb5d19c07349c304706ec5936160d988f28dac5dd78" DEPENDS = "boost qtmultimedia gstreamer" inherit cmake do_configure() { # Ensure we get the cmake configure and not qmake cmake_do_configure } export EXTRA_OECMAKE = "-DQT_QMAKE_EXECUTABLE=${OE_QMAKE_QMAKE} \ -DQT_LRELEASE_EXECUTABLE=${OE_QMAKE_LRELEASE} \ -DQT_MOC_EXECUTABLE=${OE_QMAKE_MOC} \ -DQT_UIC_EXECUTABLE=${OE_QMAKE_UIC} \ -DQT_RCC_EXECUTABLE=${OE_QMAKE_RCC} \ -DQT_LIBRARY_DIR=${OE_QMAKE_LIBDIR_QT} \ -DQT_HEADERS_DIR=${OE_QMAKE_INCDIR_QT} \ -DQT_QTCORE_INCLUDE_DIR=${OE_QMAKE_INCDIR_QT}/QtCore \ -DQT_QTGUI_INCLUDE_DIR=${OE_QMAKE_INCDIR_QT}/QtGui \ -DQTGSTREAMER_EXAMPLES=ON \ -DQT_VERSION=5 \ -DUSE_GST_PLUGIN_DIR=ON \ -DUSE_QT_PLUGIN_DIR=ON \ " ----------------------------------------------------------------------- I get the following error during configure: ----------- | -- Using Qt5 (min: 5.0.0) | CMake Error at /home/ubuntu/yocto/build/tmp/sysroots/cubox-i/usr/lib/cmake/Qt5Core/Qt5CoreConfig.cmake:27 (message): | The imported target "Qt5::Core" references the file | | "/qmake" | | but this file does not exist.

I have no idea, however, where and how it should be defined correctly. There is a file recipes-devtools/cmake/cmake_2.8.12.2.bbappend in the meta-qt5 layer, which seems to address this problem somehow: ---------------------------------------- # Ugly hack to work around undefined OE_QMAKE_PATH_EXTERNAL_HOST_BINS variable # and possibly missing qmake binary (qtbase-native can be removed from sysroot # e.g. in order to upgrade it, even when there is target qtbase) #| -- Performing Test run_pic_test - Success #| CMake Error at tmp-eglibc/sysroots/qemuarm/usr/lib/cmake/Qt5Core/Qt5CoreConfig.cmake:27 (message): #| The imported target "Qt5::Core" references the file #| #| "/qmake" #| #| but this file does not exist.

Can anybody hint me into the right direction?
