Error during the build/start process

[Temeteron]

After building the library, when i run the command:
sudo make install

to start pi-blaster, i get the following output:

root@9243439:/app/pi-blaster# sudo make install
make[1]: Entering directory '/app/pi-blaster'
 /bin/mkdir -p '/usr/sbin'
  /usr/bin/install -c pi-blaster '/usr/sbin'
 /bin/mkdir -p '/lib/systemd/system'
 /usr/bin/install -c -m 644 pi-blaster.service '/lib/systemd/system'
make  install-data-hook
make[2]: Entering directory '/app/pi-blaster'
systemctl enable pi-blaster
systemctl start pi-blaster

As it seems some errors came up. I cloned this project and followed the instructions.

Those errors don't particularly "affect" my project, since i can run/start manually the pi-blaster successfully via the command:
sudo ./pi-blaster
and start using my servo motor.
