Bug#1011428: cdbackup: reproducible-builds: embedded build paths in various binaries
Vagrant Cascadian

Severity: normal

The build path is embedded in /usr/bin/cdbackup and /usr/bin/cdrestore:
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/cdbackup.html
/build/1st/cdbackup-0.7.1/cdbackup.c:421
vs.
/build/2/cdbackup-0.7.1/2nd/cdbackup.c:421
The attached patch fixes this by explicitly passing CFLAGS to
dh_auto_build in debian/rules, which includes the -ffile-prefix-map
argument to avoid embedding the absolute path in compiled files.
With this patch applied, cdbackup should build reproducibly on
tests.reproducible-builds.org!
live well,
vagrant
