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, vagrant

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.
