Bug#1037300: comedilib: reproducible-builds: Embedded buildpaths and usrmerge paths in various files

[Vagrant Cascadian]

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

The build path and various binary paths are embedded in two demo files
and the build path changes the buildid of /usr/bin/comedi_soft_calibrate
and /usr/bin/comedi_calibrate:

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

  /usr/share/doc/libcomedi-dev/demo/pwm.gz

  #!·/bin/bash
  vs.
  #!·/bin/sh

  lt_dump_D=`$ECHO·"X$lt_script_arg0"·|·/bin/sed·-e·'s/^X//'·-e·'s%/[^/]*$%%'`
  vs.
  lt_dump_D=`$ECHO·"X$lt_script_arg0"·|·/usr/bin/sed·-e·'s/^X//'·-e·'s%/[^/]*$%%'`
  
  LD_LIBRARY_PATH="/build/1st/comedilib-0.11.0+5/lib/.libs:$LD_LIBRARY_PATH"
  vs.
  LD_LIBRARY_PATH="/build/2/comedilib-0.11.0+5/2nd/lib/.libs:$LD_LIBRARY_PATH"

The attached patches fix this by adjusting these values from the
debian/rules, and passing CFLAGS and CXXFLAGS to the appropriate
configure target.


According to my local tests, with these patches applied comedilib should
build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining comedilib!

live well,
