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
