Qt5 yocto build for RPi 3B fails

[MartinD]

Hi,
I'm Yocto (Dunfell) building Qt5 for Raspberry Pi 3B on Ubuntu 18.04 and it fails when building Qt:

| Makefile:47: recipe for target 'sub-auto-make_first' failed
| make: *** [sub-auto-make_first] Error 2
| ERROR: oe_runmake failed
| WARNING: exit code 1 from a shell command.
| ERROR: Execution of '/home/martin/Downloads/yocto/build/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtbase/5.14.2+gitAUTOINC+3a6d8df521-r0/temp/run.do_compile_ptest_base.29914' failed with exit code 1
ERROR: Task (/home/martin/Downloads/yocto/build/../sources/meta-qt5/recipes-qt/qt5/qtbase_git.bb:do_compile_ptest_base) failed with exit code '1'
NOTE: Tasks Summary: Attempted 3598 tasks of which 3597 didn't need to be rerun and 1 failed.

I only added this to local.conf:

IMAGE_INSTALL += " \
                 ${Qt_UTILS} \
		"

Qt_UTILS = " \
		qtbase \
		qtbase-tools \
		qtdeclarative \
		qtquickcontrols \
		qtquickcontrols2 \
		"

Any idea how to fix it?

The issue was probably insufficient RAM on my VirtualBox machine.
