The build path is embedded in /usr/bin/lopsubgen: https://tests.reproducible-builds.org/debian/rb-pkg/trixie/amd64/diffoscope-results/liblopsub.html /build/1st/liblopsub-1.0.3/lopsubgen.c:49 vs. /build/2/liblopsub-1.0.3/2nd/lopsubgen.c:49 The attached patch fixes this by passing the -ffile-prefix-map argument to the compiler in the upstream Makefile. According to my local tests, with this patch and the recently submitted timestamp patches applied, liblopsub should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining liblopsub! live well, vagrant
