How do we build on raspberry pi after this recent change?

https://github.com/repaper/gratis/commit/5c5debe5de40178874d00f419bf02e008873b042

Gives error:

i'm glad it's not just me. the adafruit tutorial also makes no sense now. https://forums.adafruit.com/viewtopic.php?f=47&t=102608&p=514370#p514370

adafruit are referring people here, but this documentation is also wrong.

I changed the Makefile a little to set better defaults and fix some mkdir bugs in it

So it works with RasPi now?

I was able to compile and run with the following:

cd gratis
make rpi EPD_IO=epd_io_free_uart.h PANEL_VERSION='V231_G2'
sudo make rpi-install EPD_IO=epd_io_free_uart.h PANEL_VERSION='V231_G2'
sudo systemctl start epd-fuse
python2 ~/gratis/PlatformWithOS/demo/ClockDemo.py

I used the alternate header because I built a new cable with a single large connector and the console port attached to USB serial rather than the separate wires cable. (/etc/default/epd-fuse was set to 2.0")

the Rpi V2B is running arch Linux:

Linux 4.4.20-1-ARCH #1 SMP Wed Sep 7 19:10:13 MDT 2016 armv7l GNU/Linux

I think this is ok now, if not please open new issue.

Me and @shawaj have been testing this. It seems that there is an error in the makefile? It compiles correctly now, but we get the following error when trying to start the service:

Job for epd-fuse.service failed. See 'systemctl status epd-fuse.service' and 'journalctl -xn' for details.

When checking systemctl status epd-fuse.service we get the following errors:

● epd-fuse.service - A Fuse driver for the Repaper.org EPD
   Loaded: loaded (/usr/lib/systemd/system/epd-fuse.service; enabled)

Any further thoughts?
