Source: vxl
Version: 1.17.0.dfsg2-1
Severity: serious
Justification: ABI break since stable when rebuilt
Tags: sid stretch
User: debian-...@lists.debian.org
Usertags: libstdc++-cxx11
Background[1]: libstdc++6 introduces a new ABI to conform to the
C++11 standard, but keeps the old ABI to not break existing binaries.
Packages which are built with g++-5 from experimental (not the one
from testing/unstable) are using the new ABI. Libraries built from
this source package export some of the new __cxx11 or B5cxx11 symbols,
dropping other symbols. If these symbols are part of the API of
the library, then this rebuild with g++-5 will trigger a transition
for the library.
In the case of vxl, there's some std::string use in headers that
are installed (for example vgui_window::set_title), so a transition
does appear to be needed. The transition normally consists of renaming
the affected library packages, adding a v5 suffix (libvxl1.17v5). The
upstream-provided SONAME should not be changed.
If an upgrade to a new upstream SONAME is already planned, and that
SONAME has never been available in Debian compiled with g++-4, then an
alternative way to carry out the transition would be to bump the
SONAME. However, the libstdc++ transition has been going on for nearly
2 months already, and anything that makes it take longer is bad for Debian,
so introducing new upstream code is not recommended at this stage.
These follow-up transitions for libstdc++ are not going through exactly
the normal transition procedure, because many entangled transitions are
going on at the same time, and the usual ordered transition procedure
does not scale that far. When all the C++ libraries on which this library
depends have started their transitions in unstable if required, this
library should do the same, closing this bug; the release team will deal
with binNMUs as needed.
Looking at the build-dependencies of vxl:
* coin, dcmtk have already had their renames
* Qt did not need a rename
* the rest appear to be C ABIs
so I think vxl is ready to go.
The package might be NMU'd if there is no maintainer response. The
release team have declared a 2 day NMU delay[2] for packages involved
in the libstdc++ transition, in order to get unstable back to a usable
state in a finite time.
