Source: pacman Severity: normal Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: buildpath X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org The build path is embedded in /usr/games/pacman: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/pacman.html /build/1st/pacman-10/pac.cc:85 vs. /build/2/pacman-10/2nd/pac.cc:85 The attached patch fixes this adjusting the generated Makefile from debian/rules to include -ffile-prefix-map in the CXXFLAGS_DEFINES variable. Alternately, it might be worth using "dpkg-buildflags --get CXXFLAGS" instead of hard-coding -ffile-prefix-map, and will benefit from other useful flags as well. According to my local tests, with this patch applied, pacman should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining pacman! live well, vagrant
