Bug#1020651: xmlrpc-epi: reproducible-builds: Embedded build path in libxmlrpc-epi.so.*

[Vagrant Cascadian]

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

The build path is embedded in
/usr/lib/debug/usr/lib/x86_64-linux-gnu/libxmlrpc-epi.so.0.0.3:

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

  0»      (line_strp)» (offset:·0x0):·/build/1st/xmlrpc-epi-0.54.2/src
  vs.
  0»      (line_strp)» (offset:·0x0):·/build/2/xmlrpc-epi-0.54.2/2nd/src  

The attached patch fixes this by passing the -ffile-prefix-map argument
via CFLAGS in debian/rules.

Another option that *might* fix this and other issues would be to switch
to dh and a recent debhelper compat level.


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


Thanks for maintaining xmlrpc-epi!


live well,
