Severity: wishlist

Hi!
While working on the “reproducible builds” effort [1], we have noticed
that ncurses could not be built reproducibly.
The attached patch will add calls to strip-nondeterminism on static
libraries. Once applied, the package can be built reproducibly with our
current experimental framework.
I've initially tried to run `ar` in deterministic mode by passing
ARFLAGS="Dcrv". Unfortunately, `ranlib` is called after `ar` and there
doesn't seem to be a way to pass the `-D` flag to it, and so it will
write a timestamp in the newly created index.

Subject: [PATCH] Call strip-nondeterminism on static libraries
Static libraries will unfortunately contain timestamps, preventing the
package to be built reproducibly. strip-nondeterminism will take care
of normalizing the libraries.
Passing 'Dcvr' as ARFLAGS to configure is unfortunately not enough.
The build process also calls ranlib, and there doesn't seem to be
a way to give it the '-D' flag.

indeed, closing the bug now! :)
as you can see ncurses is now reproducible:
