Bug#794990: mrpt: ftbfs with new libstdc++ ABI

[Matthias Klose]

Michael,

you probably missed
https://lists.debian.org/debian-devel-announce/2015/08/msg2.html

unless you rebuilt all build dependencies using GCC 5, you can't tell anything
if mrpt will need a transition or not.

The error messages at show that at least opencv needs a transition (which needs
some transitions itself). So please be patient and/or help with the transitions.

thanks, Matthias

Bug#794990: mrpt: ftbfs with new libstdc++ ABI

[Michael Gilbert]

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_stringchar,
std::char_traitschar, std::allocatorchar  const,
std::__cxx11::basic_stringchar, std::char_traitschar,
std::allocatorchar  const, std::__cxx11::basic_stringchar,
std::char_traitschar, std::allocatorchar  const, int)'
../../lib/libmrpt-hwdrivers.so.1.3.1: undefined reference to
`cv::FileStorage::FileStorage(std::__cxx11::basic_stringchar,
std::char_traitschar, std::allocatorchar  const, int,
std::__cxx11::basic_stringchar, std::char_traitschar,
std::allocatorchar  const)'
../../lib/libmrpt-vision.so.1.3.1: undefined reference to
`cv::Algorithm::_create(std::__cxx11::basic_stringchar,
std::char_traitschar, std::allocatorchar  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
