Thank you for your reply.
HELLO's value in two bbfiles is same when using ':=', but it brought new errors:
ERROR: When reparsing a.bb and b.bb: the basehash value changed from
xxxx to xxxx. The metadata is not deterministic and this needs to be
fixed.
What could be the reason? My guess is that, during reparses, bitbake
also calls the random_number_function multiple times, causing
different random numbers to be generated each time and thus resulting
in different hash values.
I am a beginner, and this issue is a bit complex for me. So, I took
the following approach: I wrote the random number to a file using a
recipe, and other bbfiles use it by reading the random number file.
Is there a good idea? Thanks again!
