[manjaro-packages] C++ ABI bump rebuild (announcement)

[Philip Müller]

Hi all,

GCC-5.x release libstdc++ with a dual ABI [1].  We have now switched to
the new ABI in our [unstable].

While the old C++ ABI is still available, it is recommended that you
build all non-repo and overlay packages to have the new ABI. This is
particularly if they link to another library built against the new ABI.
 You can get the list of packages to rebuild using the following:

for i in $(pacman -Qqm); do
  if pacman -Qql $i | xargs readelf -d 2>/dev/null | grep -q
libstdc++.so.6; then
    echo $i;
  fi;
done
