Problem in bitbake dey-image-qt -c popluate_sdk

Build Configuration:
BB_VERSION = “1.44.0”
BUILD_SYS = “x86_64-linux”
TARGET_SYS = “arm-dey-linux-gnueabi”
MACHINE = “ccimx6ulsbc”
DISTRO = “dey”
TUNE_FEATURES = “arm vfp cortexa7 neon thumb callconvention-hard”
TARGET_FPU = “hard”

When I execute bitbake dey-image-qt -c popluate_sdk some compilation tasks don’t end and continues for hours. I run this command on a 8 core, 8 gb virtual machine and at last I stopped the build tasks after 9 hours. What might be the reason? How can I investigate the problem?

Thank you.

The correct command is
bitbake -c populate_sdk dey-image-qt
