Subject: autoclass: reproducible-builds: build path triggers differing buildid

Date: Sat, 21 May 2022 18:34:52 -0700

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

Source: autoclass
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 triggers different buildid in /usr/bin/autoclass:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/autoclass.html

  ... Build·ID:·f5e1b2ff65fbb0f313e8226b27292971816a02ad
  vs.
  ... Build·ID:·22e32d5a1dcc2e0b76bf97d7607bc09be61dbbd1

The attached patch fixes this by passing -ffile-prefix-map to CFLAGS in
debian/rules, and passing CFLAGS to make.

Alternately (maybe even preferably), updating to "dh" build system and
updating debhelper compat level might also fix the issue.

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


live well,

Without this argument, the build path gets embedded in the binaries.
