undefined symbol: gdk_display_get_primary_monitor

I was trying to launch TuringBot software that I just installed on my Linux 16.04, and I got an error:

./TuringBot: symbol lookup error: ./TuringBot: undefined symbol: gdk_display_get_primary_monitor

I have tried upgrading my system

sudo apt-get update
sudo apt-get upgrade

but the problem still exists. Does anybody know how to fix this problem?

Thanks a lot!

Cheers

Solution

  • I assume that you mean Ubuntu 16.04 (as "Linux 16.04" doesn't exist).

    The reason why it doesn't work is because the GTK version of Ubuntu 16.04 is too old (it has version 3.18.9) while gdk_display_get_primary_monitor() was only added in GTK 3.22.

    The easiest way to fix it is probably to upgrade to a newer Ubuntu version.
