Bug#1105341: dsdp: FTBFS with make --shuffle=reverse: ld: cannot find m

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.

More information about this mass bug filing is available at https://wiki.debian.org/qa.debian.org/FTBFS/Shuffle

Relevant part (hopefully):

gcc -fPIC -O3 -o maxcut maxcut.o /build/reproducible-path/dsdp-5.8/lib/libdsdp.a -llapack -lblas -lm
/usr/bin/ld: cannot find maxcut.o: No such file or directory
collect2: error: ld returned 1 exit status

The full build log is available from: http://qa-logs.debian.net/2025/05/05/shuffle/reverse/dsdp_5.8-10.1_unstable_reverse.log

If you reassign this bug to another package, please mark it as 'affects'-ing this package. See https://www.debian.org/Bugs/server-control#affects
