Dear all,

I will need to rebuild some of my packages which I maintain myself for readline 7.0.

Is there a reliable way to find out which packages need a rebuild? How was the rebuild list for the official repos made?

Thanks Bastian

Well, any packages which depend on readline can be assumed to require a rebuild...

Or you could check for files which link to libhistory.so.6 or libreadline.so.6

There is even a shell snippet which can be repurposed to do that for you, on the Arch website in the news feed (it was used during the C++ ABI change)

​ Thanks, ​ ​ I've used this ​ now​ : #!/bin/bash while read pkg; do mapfile -t files < <(pacman -Qlq $pkg | grep -v /$) grep -Fq libreadline.so.6 "${files[@]}" <&- 2>/dev/null && echo $pkg done < <(pacman -Qmq) That's what I was looking for. Cheers Bastian ​

readline now provides libreadline.so and packages can depend on that to trigger dependency errors (which are one good way of warning you a rebuild is necessary...)
