Description
|
The Build ID differs, but there are no other differences.
.
Specifically, NT_GNU_BUILD_ID, .gnu_debuglink, and
/usr/lib/debug/build-id/* filenames differ, but there are no other
differences.
.
[On 'sope' seen also a difference in a .GCC.command.line section; compare 'records_build_flags'.]
.
If there _are_ other differences (or if diffoscope output is truncated),
don't tag with this issue, but look for the root problem, as explained
under build_id_variation_requiring_further_investigation.
.
When this occurs on unstable but not on testing, it's likely a form
of captures_build_path. If it uses the cmake buildsystem, very
likely to be cmake_rpath_contains_build_path.

ftbfs_due_to_f-file-prefix-map
|
|
Description
|
An example of failure related to this are programs that expect
__FILE__ to expand to some absolute path, but instead finding themselves
a relative one.
.
In our unstable and experimental build systems we export
DEB_BUILD_OPTIONS=reproducible=+all
that makes dpkg-buildflags enable the reproducible/fixfilepath feature, adding
-ffile-prefix-map=BUILDPATH=.
to CFLAGS, CXXFLAGS, OBJCFLAGS, OBJCXXFLAGS, GCJFLAGS, FFLAGS and FCFLAGS.

Description
|
When an executable is linked with a shared library from the same project,
RPATH will contain the build path. Even if this is stripped on installation,
the build-id will remain unchanged.
.
With CMake 3.14+, packages can set `-DCMAKE_BUILD_RPATH_USE_ORIGIN=ON` to
fix the issue. This is done automatically when using the currently
experimental debhelper compat level v14.
https://cmake.org/cmake/help/latest/prop_tgt/BUILD_RPATH_USE_ORIGIN.html
.
When working with older CMake versions, the `CMAKE_SKIP_RPATH` option can be
enabled instead, but it may be required to also set `LD_LIBRARY_PATH` while
running tests.
