Subject: bagel: reproducible-builds: build path embedded in /usr/bin/BAGEL and debug symbols

Date: Wed, 19 Jan 2022 08:14:17 -0800

[Message part 1 (text/plain, inline)]

Source: bagel
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

Different build paths trigger reproducibility issues with binaries such
as /usr/bin/BAGEL and relevent debugging symbols.

The attached patch fixes this by passing -ffile-prefix-map to CXXFLAGS
to avoid embedding the build path into the binaries.

Another possibility would be to use dpkg-buildflags, which includes this
flag by default.


With this patch applied, bagel should build reproducibly on
tests.reproducible-builds.org!


Thanks for maintaining bagel!


live well,

Subject: [PATCH] debian/rules: Pass -ffile-prefix-map in CXXFLAGS.

The -ffile-prefix-map argument is used to avoid embedding the build
path in binaries, which allows for reproducible builds regardless of
the build path in the build environment.
