In local.conf I put:

     INHERIT += "sp-version"

In classes/sp-version.bbclass

     def read_spbaseversion(d):
	# The goal of this function is to read and
	# parse a file from the layer
         bb.warn("MYSELF: ", d.getVar('FILE', False))
         return '0'

     SP_BASEVERSION := "${@read_spbaseversion(d)}"

Then both on Krogoth and Pyro, the following command returns:

     $ bitbake -e |tee var.txt |grep MYSELF

WARNING: MYSELF: /home/s/bughunt-pyro/build/conf/bblayers.conf
WARNING: MYSELF: /home/s/bughunt-pyro/build/conf/bblayers.conf
     bb.warn("MYSELF: ", d.getVar('FILE', False))

Likewise:

     $ bitbake -e sp-image |tee sp-image.txt |grep MYSELF

WARNING: MYSELF: /home/s/bughunt-pyro/build/conf/bblayers.conf
WARNING: MYSELF: /home/s/bughunt-pyro/build/conf/bblayers.conf
WARNING: MYSELF: /home/s/bughunt-pyro/build/conf/bblayers.conf
     bb.warn("MYSELF: ", d.getVar('FILE', False))


Is there an alternative to d.getVar() to access the "other" versions of 
the variable?


Best regards,
Svein
