Build 1.7.3 failed on based ArchLinux system

[Turbo]

Bonjour,

I was trying to build SooperLopper 1.7.3 on ArchLinux based OS (Antergos and Manjaro), on both architecture i686 and X86_64, but it failed. libsigc++-1.2.7 and libsigc++-2.6.1 are installed. SooperLopper version 1.7.1 & 1.7.2 failed too but 1.7.0 is ok.

Please see the attachement file more details.

Thank you.
