Subject: logtools: reproducible-builds: Embedded build paths in binaries

Date: Sat, 24 Sep 2022 15:23:58 -0700

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

Source: logtools
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 embedded in various binaries in /usr/bin:

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

  /usr/bin/clfdomainsplit

  /build/1st/logtools-0.13e+nmu2/clfdomainsplit.cpp:174
  vs.
  /build/2/logtools-0.13e+nmu2/2nd/clfdomainsplit.cpp:174


The attached patch fixes this by adding the -ffile-prefix-map argument
to CFLAGS in the upstream Makefile.in.

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

Thanks for maintaining logtools!

live well,
