Bug#991180: xaw3d: reproducible builds: Embeds build path in libXaw3d.so

[Vagrant Cascadian]

Source: xaw3d
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 places in libXaw3d.so.*:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/xaw3d.html

  ./usr/lib/x86_64-linux-gnu/libXaw3d.so.6.1

  /build/1st/xaw3d-1.5+F/xc/lib/Xaw3d/AsciiSrc.c:263
  vs.
  /build/2/xaw3d-1.5+F/2nd/xc/lib/Xaw3d/AsciiSrc.c:263

The attached patch fixes this by passing -ffile-prefix-map and -I. to
CFLAGS in debian/rules to avoid embedding the build path.


Thanks for maintaining xaw3d!


live well,
