Source: icon Severity: normal Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: buildpath X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org The buildid varies when built from a different path for /usr/bin/icont and /usr/bin/iconx: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/icon.html The attached patch to debian/rules fixes this by adding -ffile-prefix-map to CFLAGS, and adjusting a call to sed to handle "/" in the expression. According to my local tests, with this patch applied, icon should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining icon! live well, vagrant
From 0235dc52092db96208f3e0c051a10b0dbccf127d Mon Sep 17 00:00:00 2001 From: Vagrant Cascadian <vagrant@reproducible-builds.org> Date: Sat, 8 Oct 2022 23:12:15 +0000 Subject: [PATCH] debian/rules: Add -ffile-prefix-map to CFLAGS to avoid embedded build paths. Adjust call to sed to handle "/" in the expression. While the build path doesn't directly show up in the binaries, the buildid may differs dependent on the build path. --- debian/rules | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/debian/rules b/debian/rules index 006ceb1..e5377bd 100755 --- a/debian/rules +++ b/debian/rules @@ -30,9 +30,12 @@ endif CFLAGS = -Wall -g $(CFLAGS_OPT) +# Avoid embedding build paths for reproducible builds +CFLAGS += -ffile-prefix-map=$(CURDIR)=. + configure: $(MAKE) X-Configure name=$(system) - sed "s/CFLAGS = .*/CFLAGS = $(CFLAGS)/" Makedefs > Makedefs.tmp + sed "s%CFLAGS = .*%CFLAGS = $(CFLAGS)%" Makedefs > Makedefs.tmp echo "ASFLAGS = -Wa,--noexecstack" >> Makedefs.tmp mv Makedefs.tmp Makedefs touch $@ -- 2.37.2
