Source: fstrcmp 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 debug symbols: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/fstrcmp.html ./usr/lib/debug/usr/bin/fstrcmp 0» (line_strp)» (offset:·0x0):·/build/1st/fstrcmp-0.7.D001 vs. 0» (line_strp)» (offset:·0xf):·/build/2/fstrcmp-0.7.D001/2nd The attached patch fixes this by setting -ffile-prefix-map in CFLAGS in debian/rules, which avoids embedding the absolute build path. Alternately, switching to use a newer debhelper compat level and the dh build system would likely also fix this, as it includes -ffile-prefix-map by default. With this patch applied, fstrcmp should build reproducibly on tests.reproducible-builds.org! live well, vagrant
