The build path is embedded in /usr/bin/png23d: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/png23d.html /build/1st/png23d-1.10/png23d.c:32 vs. /build/2/png23d-1.10/2nd/png23d.c:32 The attached patch to to the upstream Makefile fixes this by adding -ffile-prefix-map to CFLAGS. According to my local tests, with this patch applied png23d should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining png23d! live well, vagrant
