Source: mrpt
Version: 1:1.2.2-1.1
Severity: serious
Justification: fails to build from source (but built successfully in the past)
User: debian-...@lists.debian.org
Usertags: libstdc++-cxx11
This package fails to build with the new libstdc++ ABI (with updated
libassimp3, #794835).
The error has to do with undefined references to c++11 symbols:
../../lib/libmrpt-vision.so.1.3.1: undefined reference to
`cv::Exception::Exception(int, std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&, std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&, int)'
../../lib/libmrpt-hwdrivers.so.1.3.1: undefined reference to
`cv::FileStorage::FileStorage(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&, int,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&)'
../../lib/libmrpt-vision.so.1.3.1: undefined reference to
`cv::Algorithm::_create(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)'
collect2: error: ld returned 1 exit status
apps/camera-calib/CMakeFiles/camera-calib.dir/build.make:215: recipe
for target 'bin/camera-calib' failed
Forcing the build to use g++-4.9 or -std=c++98 doesn't help.
Best wishes,
Mike

That transition has started, and I can confirm that mrpt builds successfully
in a sid amd64 sbuild. Closing this.

mrpt does have cxx11 symbols itself, but it appears to be a leaf package:
nothing in unstable depends or build-depends on it,
according to "dak rm -R -n mrpt".
The maintainer is free to do the "v5" package rename as outlined in
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=796854> if they want
to do so, but I don't think it is necessary to carry out a transition
if the maintainer is not aware of reverse dependencies outside Debian.
