gdb - Could not load shared library symbols for linux-vdso.so.1. while debugging

Question

Not loading VDSO.so is one of the famous bugs you encounter while using gdb and glibc >2.2. I found that was planned to get repaired in gdb 7.5.1, but it wasn't. Okay I found a work-around here Here, but I didn't understand it so how to apply it.

OS: Arch Linux
IDE : QT creator 3.0.82
Compiler : GCC 4.8.2
NB: I am not sure if I am breaking the rules including the link above

No, it's not. The problem here is simply a useless warning, which you can safely ignore.

You didn't find a "workaround". You found a patch to GDB, which disables the warning.

To apply it, use the patch command, and then build your own GDB. But it is much simpler to just ignore the warning in the first place.
