Bug#1020754: shapetools: reproducible-builds: Embedded build path in sttk.h

[Vagrant Cascadian]

Source: shapetools
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/include/sttk.h:

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

  #define·ST_ENV_DEFAULT»  "/build/1st/shapetools-1.4pl6/debian/tmp/usr"
  vs.
  #define·ST_ENV_DEFAULT»  "/build/2/shapetools-1.4pl6/2nd/debian/tmp/usr"

The attached patch fixes this in debian/rules by removing the build path
and debian/tmp from sttk.h. It is unclear to me if it would be better to
replace it with a placeholder value, or to leave the debian/tmp part; it
really depends how this define is used.

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

Thanks for maintaining shapetools!

live well,
  vagrant
