Subject: pcp: reproducible-builds: build path embedded in various libraries

Date: Sun, 06 Mar 2022 17:06:29 -0800

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

Source: pcp
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 and resulting Build ID for various libraries is embedded:

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

  /usr/lib/x86_64-linux-gnu/perl5/5.34/auto/PCP/LogImport/LogImport.so

  /build/1st/pcp-5.3.6/src/libpcp_import/src:/build/1st/pcp-5.3.6/src/libpcp/src
  vs.
  /build/2/pcp-5.3.6/2nd/src/libpcp_import/src:/build/2/pcp-5.3.6/2nd/src/libpcp/src

The attached patch to debian/rules fixes this by using the standard
standard buildflags from dpkg-buildflags, which includes
-ffile-prefix-map to strip out the build paths.


An alternate patch for debian/rules could be something like:

  CFLAGS += -ffile-prefix-map=$(CURDIR)=.
  export CFLAGS

Though you might also have to set this for various other *FLAGS as well.


This patch does not address all reproducibility issues, but should
significantly reduce the size of the diff, making it easier to identify
remaining issues.


live well,
