Bug#862113: gcc-6: Generate reproducible output independently of the build path
Package: gcc-6
Version: 6.3.0-16
Severity: wishlist
Tags: patch upstream
User: reproducible-builds@lists.alioth.debian.org
Usertags: build-path
Dear Maintainer,
I've been asked to file this bug report so that others working on the
Reproducible Builds project can better track the ongoing issue of
build-path-independent reproducibility in various tools and compilers. I don't
mean to imply to rush this process nor pressure you, this report is only for
informational purposes.
As you know, I've already contacted upstream with a proposed patch:
- https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00513.html
These (backported to GCC-6) may be browsed as git commits here:
- https://anonscm.debian.org/cgit/reproducible/gcc-6.git/log/?h=pu/reproducible_builds
The built packages may be downloaded here:
- https://reproducible.alioth.debian.org/debian/
- https://tests.reproducible-builds.org/debian/index_repositories.html (overview)
The reproducibility status of dependent packages is being tracked on these pages:
- https://tests.reproducible-builds.org/debian/issues/unstable/captures_build_path_issue.html
We're currently waiting to hear back from upstream to see what they think.
However, I don't think the patch is missing any functionality and is unlikely
to negatively affect any other packages.
