Hello, Thanks for your review! I realize that the problem is, I do not tell build system to ignore changes of misssing-sources (it will copy missing-sources to subprojects) thus the second build will detect unexpectes source changes.
It has been fixed by adding debian/source/options. I think you can confirm that by yourself. Do not forget to remove the moreinfo tag if you succeed later! Best regards, EiPi Fun/Don Xu 19 Dec, 2024
