I have implemented and tried it with luvOS distribution.
def check_iso_build(d):
host = d.getVar('COMPATIBLE_HOST', True)
if host:
import re
target = d.getVar('TARGET_ARCH', True)
if re.match(host, target):
return 0
return 1
NOISO ?= "${@check_iso_build(d)}"
For the following reason
The COMPATIBLE_HOST value is NULL. Now the question is why it contains
value NULL. That's simply because syslinux recipe does not inherit
bootimg.bbclass.
I did following experiment - The luv-live-image.bb inherit the
bootimg.bbclass hence I have defined the COMPATIBLE_HOST as "x86" or
"aarch64" depending on the build I am doing. This will work for x86
architecture but definitely going to break for aarch64 because of the
below condition
if re.match(host, target):
return 0
Let me know If I need to experiment/change the logic of the implementation.
