In image, the compiler arm-poky-linux-gnueabi-c++ is missing !
Does it make sense that it is not supported by default in fsl-image-qt5 ?
You can extract the toolchain for Qt5 using:
$ bitbake meta-toolchain-qt5
This will allow you to create a script to install the toolchain in your host, which includes gcc (C) and g++ (C++).
I hope this information helps!
