Subject: qt6-base: reproducible-builds: Build path embedded QtBuildInternalsExtra.cmake

Date: Thu, 24 Feb 2022 19:21:25 -0800

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

Source: qt6-base
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The path of the build environment is embedded in the
QtBuildInternalsExtra.cmake file shipped in the package:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/qt6-base.html

  /usr/lib/x86_64-linux-gnu/cmake/Qt6BuildInternals/QtBuildInternalsExtra.cmake

  set(QT_SOURCE_TREE·"/build/1st/qt6-base-6.2.2+dfsg"·CACHE·PATH
  vs.
  set(QT_SOURCE_TREE·"/build/2/qt6-base-6.2.2+dfsg/2nd"·CACHE·PATH

The attached patch fixes this by removing the code that embeds the build
path.

It does build successfully with the patch applied, though I have not
otherwise tested the package.  Another option might be to exclude this
file from the package.

For either approach, someone familiar with qt6-base would need to test
and confirm if either of these methods are ok!


With this patch applied, qt6-base should build reproducibly on
tests.reproducible-builds.org!


Thanks for maintaining qt6-base!


live well,

Subject: [PATCH] cmake/QtBuildInternalsExtra.cmake.in: Patch out embedded
 build path.

The original build path should not be needed in the shipped package,
and causes reproducibility issues when built in different paths.
