[Debian-on-mobile-maintainers] Bug#1105676: umtp-responder: FTBFS with make --shuffle=reverse: Fatal error: can't create obj/mtp_op_opensession.o: No such file or directory

Source: umtp-responder
Version: 1.3.10-1
Severity: minor

Hi,

GNU Make now has a --shuffle option that simulates non-deterministic ordering
of target prerequisites. See
https://trofi.github.io/posts/238-new-make-shuffle-mode.html and also previous
work in Debian by Santiago Vila:
https://people.debian.org/~sanvila/make-shuffle/

This package fails to build with make --shuffle=reverse.
This is likely to be caused by a missing dependency in
debian/rules or an upstream Makefile.

Relevant part (hopefully):
