Source: scsitools 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 various binaries: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/scsitools.html /sbin/scsi-spin /build/1st/scsitools-0.12/debian/scsi-spin.c:290 vs. /build/2/scsitools-0.12/2nd/debian/scsi-spin.c:290 The attached patch fixes this by setting -ffile-prefix-map in CFLAGS, and explicitly passing CFLAGS to make in debian/rules. The -ffile-prefix-map compiler flag is used to avoid embedding the absolute path in compiled files. Alternately, switching to use the default CFLAGS from dpkg-buildflags (possibly through using a newer debhelper compat version) also would include -ffile-prefix-map by default. With this patch applied, scsitools should build reproducibly on tests.reproducible-builds.org! live well, vagrant
