I need to run a software application on top of the yocto image I'm building for Minnowboard. The main configuration needed is Qt5.
I was able to build a sample test image for Minnowboard according to the latest yocto guide by adding meta-intel layer with MACHINE intel-corei7-64 and EXTRA_IMAGE_FEATURES ?= "dev-pkgs"
But I'm having trouble with building Qt support for my yocto image. I added meta-qt5 layer and tried to compile for meta-toolchain-qt5 so that according to this guide I can setup Qt-creator in my host machine to cross compile for Minnowboard.
But meta-toolchain-qt5 is keep failing with many errors.
Summary: 7 tasks failed: /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qtwebsockets_git.bb:do_compile /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qtenginio_git.bb:do_install /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qtgraphicaleffects_git.bb:do_compile /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qt3d_git.bb:do_compile /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qtconnectivity_git.bb:do_compile /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qtquickcontrols2_git.bb:do_compile /home/holoplot/Yocto/poky/meta-qt5/recipes-qt/qt5/qtsensors_git.bb:do_compile
ATM, I'm using PYRO branch for all layers. I added following layers (openembedded-core/meta , meta-openembedded/meta-oe , meta-openembedded/meta-ruby , meta-openembedded/meta-multimedia in hope of a successful meta-toolchain-qt5 build but it still failed.
Is there a stable branch that I can use to successfully build the meta-toolchain-qt5 for minnowboard or should I edit the qt recipes in order to avoid building above packages which causes errors?
Any support is much appreciated. Thanks!

From your error log. This seem like has no problem with the recipe but instead the spec of your machine; Please try to increase the amount of RAM for your virtual machine;
