Package: flex Severity: normal Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: buildpath X-Debbugs-Cc: reproducible-b...@lists.alioth.debian.org
Makefiles shipped in the examples directory contain build path
variations for several values:
/usr/share/doc/flex/examples/fastwc/Makefile.gz
/usr/share/doc/flex/examples/manual/Makefile.gz
ACLOCAL·=·${SHELL}·/build/1st/flex-2.6.4/build-aux/missing·aclocal-1.16
vs.
ACLOCAL·=·${SHELL}·/build/2/flex-2.6.4/2nd/build-aux/missing·aclocal-1.16
This makes the build unreproducible when built from a different path,
but the Makefile itself would require some manual configuration anyways,
since the end-user most likely does not contain the original build path
on their system.
I'd suggest simply removing the Makefiles, as they are not functional,
or alternately, sanitizing with the attached patch to debian/rules.
live well,
