Package: libabigail0
Version: 1.0~rc6-1
Severity: serious
Tags: sid buster
User: debian-gcc@lists.debian.org
Usertags: gcc-7-op-mangling


It appears that your package provides an external symbol that is
affected by the recent name mangling changes in GCC 7. See:

In GCC 7, the name mangling for C++ conversion operators which return a
type using the abi_tag attribute (most commonly std::string) has
changed. When your library is compiled with GCC 7, it will now emit two
symbols for the conversion operator using the new and old naming.
Executables compiled with GCC 7 will always use the new symbol, while
old executables compiled using <= GCC 6 will use the old symbol. For new
executables to build without undefined references, your library will
need rebuilding with GCC 7.

To ensure that new executables will pull in the newer version of the
library built with GCC 7:
- Your library package should Build-Depend on g++ (>= 4:7).
- If your package provides a symbols file, ensure that the new
  conversion operator symbols have a version matching the version this
  bug is fixed in (including the Debian revision and tilde if

  Using apt as an example (debian/libapt-pkg5.0.symbols):
    (c++)"URI::operator std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >[abi:cxx11]()@APTPKG_5.0" 0.8.0
  + (c++)"URI::operator std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >()@APTPKG_5.0" 1.5~beta2~

  Where "1.5~beta2" is the version this bug was fixed in.

- If your package does not provide a symbols file, add a dh_makeshlibs
  override so that tight enough dependencies are generated.

  Using libebml as an example (debian/rules):
  + override_dh_makeshlibs:
  + 	# For new symbols when compiled with GCC 7
  + 	dh_makeshlibs -V'libebml4v5 (>= 1.3.4-2~)'

  Where "1.3.4-2" is the version this bug was fixed in.

- If your package is about to be renamed due to an upstream SONAME bump,
  you do not need to add any special symbols handling.

If you would like to know the exact name of the new symbols, using
"abipkgdiff" from abigail-tools might be able to help.
