Bug#1011481: tamil-gtk2im: reproducible-builds: embedded build paths

[Vagrant Cascadian]

Source: tamil-gtk2im
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 various binaries:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/tamil-gtk2im.html

  /usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/immodules/anjal-uni.so

  /build/1st/tamil-gtk2im-2.2/anjal-uni.c:112
  vs.
  /build/2/tamil-gtk2im-2.2/2nd/anjal-uni.c:112


The attached patch fixes this by passing -ffile-prefix-map to gcc in
compile-gtk2im.sh, which avoids embedding the absolute build path.


With this patch applied, tamil-gtk2im should build reproducibly on
tests.reproducible-builds.org!


live well,
