Package: simde
Severity: normal
Tags: patch
User: reproducible-bui...@lists.alioth.debian.org
Usertags: fixfilepath ftbfs
X-Debbugs-Cc: reproducible-b...@lists.alioth.debian.org
When run with DEB_BUILD_OPTIONS=reproducible=+fixfilepath, simde FTBFS:
clang: error: unknown argument: '-ffile-prefix-map=/<<PKGBUILDDIR>>=.'
This is because clang 10 is the first version to support
-ffile-prefix-map, and simde is building with the default clang version
9.
The attached patch updates to clang-10 to fix this issue.
Alternately, you could stick with the default gcc, setting in
debian/rules:
# Remove when switching to clang 10 or newer.
export DEB_BUILD_MAINT_OPTIONS=reproducible=-fixfilepath+fixdebugpath
The "fixfilepath" feature is not yet enabled by default in
dpkg-buildflags, but it is used in the tests.reproducible-builds.org
infrastructure for unstable and experimental, and might be enabled by
default for dpkg-buildflags in the future.
Thanks for maintaining simde!
live well,

Subject: [PATCH] Update to clang-10 to add support for -ffile-prefix-map.
Setting the DEB_BUILD_OPTIONS=reproducible=+fixfilepath adds
-ffile-prefix-map from dpkg-buildflags to default compiler
arguments. This feature is not currently enabled by default in
dpkg-buildflags, but is enabled for parts of the
tests.reproducible-builds.org infrastructure to solve some
reproducibility issues.

With the update of llvm-defaults to use clang version 11, simde appears
to build fine on the reproducible builds infrastructure, even when
setting "DEB_BUILD_OPTIONS=reproducible=+fixfilepath" so I do not expect
any changes are needed for simde directly. Marking as done!
