GCC 5.x contains libstdc++ with [dual ABI][1] support and 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 important if they link to another library built against the new ABI. You can get a list of packages to rebuild using the following shell script:

#!/bin/bash

while read pkg; do

mapfile -t files < <(pacman -Qlq $pkg | grep -v /$)

grep -Fq libstdc++.so.6 "${files[@]}" 2>/dev/null && echo $pkg

done < <(pacman -Qmq)

I'm getting a few results from the output of this script and I've tried rebuilding some of the smaller packages first. After installing the recompiled package(s) they still show up on the list.

Is recompiling enough or in some cases there is the need to do some changes?

They will always show on the script. If you've rebuilt, you are okay.
