MAMEWorld Forums - EmuChat - Help compiling MAME

Hello to everyone,
I've tried a couple of times in the past to compile a fresh MAME build from github
but it always fail giving me the following message

my system is
Kernel:4.15.0-38-generic x86_64 bits: 64 gcc: 7.3.0
Desktop: Cinnamon 3.8.9 (Gtk 2.24.32) dm: lightdm Distro: Linux Mint 19 Tara

I have installed the prerequisites with
sudo apt-get install git build-essential libsdl2-dev libsdl2-ttf-dev libfontconfig-dev qt5-default

Any ideas? Thanks
