The build path is embedded in /usr/bin/log4cpp-config:

  
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/log4cpp.html

  cflags="$cflags··-g·-O2·-ffile-prefix-map=/build/1st/log4cpp-1.1.3=. ...
  vs.
  cflags="$cflags··-g·-O2·-ffile-prefix-map=/build/2/log4cpp-1.1.3/2nd=. ...

The attached patch fixes this in debian/rules by replacing the build
path with a placeholder string in /usr/bin/log4cpp-config.

With this patch applied log4cpp should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining log4cpp!

live well,
