Dear Pierre-Alexis,
ERROR: Task 1692 > (/home/Guz/poky/meta-openembedded/meta-python/recipes-devtools/python/ > python-dbus_1.2.4.bb, do_compile) failed with exit code '1' > > A failure in python-dbus in not related to any setup in meta-ros. It is probable due to the fact that you use Poky krogoth with the master branch of meta-openembedded whereas you would be better using the krogoth branch of meta-openembedded. Probably then the failure disappears. Best regards, Lukas
