[Debian-med-packaging] Bug#971408: simde: FTBFS when dpkg-buildflags passes -ffile-prefix-map

[Vagrant Cascadian]

Package: simde
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: fixfilepath ftbfs
X-Debbugs-Cc: reproducible-bugs at 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,
