Subject: xserver-xorg-input-joystick: reproducible-builds: Embedded build path in joystick_drv.so

Date: Sun, 25 Sep 2022 11:24:31 -0700

[Message part 1 (text/plain, inline)]

Source: xserver-xorg-input-joystick
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The build path is embedded in /usr/lib/xorg/modules/input/joystick_drv.so:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/xserver-xorg-input-joystick.html

  /build/1st/xserver-xorg-input-joystick-1.6.3/build/src/../../src/jstk.c:298
  vs.
  /build/2/xserver-xorg-input-joystick-1.6.3/2nd/build/src/../../src/jstk.c:298

The attached patch fixes this in debian/rules by passing
-ffile-prefix-map in CFLAGS to configure.

With this patch applied xserver-xorg-input-joystick should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining xserver-xorg-input-joystick!

live well,
