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.

gcc_captures_build_path
|
|
Description
|
Captures build path, e.g., /build/1st/foo-42.0 v. /build/foo-42.0/2nd
.
Until early 2024 we varied the build path when testing packages from unstable
and experimental, which we have stopped doing now as the build path is recorded
as part of the environment and thus can be used when rebuilding.
.
This issue is kept here for the time being.
.
dpkg-buildflags version 1.20.6+ sets -ffile-prefix-map by default
(and -fdebug-prefix-map in older versions) which fixes this issue
in many cases, but not all (see: records_build_flags).
.
There are patches submitted upstream to address this specific issue, but they
are unlikely to be merged at this point:
.
https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00513.html
.
When this is accepted into GCC upstream, we could remove this note.
In the meantime, please do not remove this issue, nor mark it as deterministic,
nor untag these packages.

Comments:

rpath issue fixed by -DCMAKE_BUILD_RPATH_USE_ORIGIN=ON
.
Two uses of __FILE__ in src/saslplugin/plugin_common.h for "Out of
Memory" and "Parameter Error".
