Hi,
thanks for the quick reply I tried your suggestion but I get:
ERROR: Unable to parse Var <DISTRO_VERSION[:=]>
Traceback (most recent call last):
File "Var <DISTRO_VERSION[:=]>", line 1, in <module>
bb.data_smart.ExpansionError: Failure expanding variable
DISTRO_VERSION[:=], expression was ${@my_distro_version(d)} which triggered
exception NameError: name 'my_distro_version' is not defined
I think in this case the INHERIT doesn't work !
Best regards,
