[arch-dev-public] C++ ABI rebuild announcement

Here is a draft announcement. --BEGIN-- C++ ABI rebuild GCC-5.x release libstdc++ with a dual ABI [1]. We have now switched to the new ABI. While the old C++ ABI is still available, it is recommended that you build all non-repo 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 [1] https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html --END--
